Discovery of an unknown diversity of Leucinodes species damaging Solanaceae fruits in sub-Saharan Africa and moving in trade (Insecta, Lepidoptera, Pyraloidea).

The larvae of the Old World genera Leucinodes Guenée, 1854 and Sceliodes Guenée, 1854 are internal feeders in the fruits of Solanaceae, causing economic damage to cultivated plants like Solanummelongena and Solanumaethiopicum. In sub-Saharan Africa five nominal species of Leucinodes and one of Sceliodes occur. One of these species, the eggplant fruit and shoot borer Leucinodesorbonalis Guenée, 1854, is regarded as regularly intercepted from Africa and Asia in Europe, North and South America and is therefore a quarantine pest on these continents. We investigate the taxonomy of African Leucinodes and Sceliodes based on morphological characters in wing pattern, genitalia and larvae, as well as mitochondrial DNA, providing these data for identification of all life stages. The results suggest that both genera are congeneric, with Sceliodes syn. n. established as junior subjective synonym of Leucinodes. Leucinodesorbonalis is described from Asia and none of the samples investigated from Africa belong to this species. Instead, sub-Saharan Africa harbours a complex of eight endemic Leucinodes species. Among the former nominal species of Leucinodes (and Sceliodes) from Africa, only Leucinodeslaisalis (Walker, 1859), comb. n. (Sceliodes) is confirmed, with Leucinodestranslucidalis Gaede, 1917, syn. n. as a junior subjective synonym. The other African Leucinodes species were unknown to science and are described as new: Leucinodesafricensis sp. n., Leucinodesethiopica sp. n., Leucinodeskenyensis sp. n., Leucinodesmalawiensis sp. n., Leucinodespseudorbonalis sp. n., Leucinodesrimavallis sp. n. and Leucinodesugandensis sp. n. An identification key based on male genitalia is provided for the African Leucinodes species. Most imports of Leucinodes specimens from Africa into Europe refer to Leucinodesafricensis, which has been frequently imported with fruits during the last 50 years. In contrast, Leucinodeslaisalis has been much less frequently recorded, and Leucinodespseudorbonalis as well as Leucinodesrimavallis only very recently in fruit imports from Uganda. Accordingly, interceptions of Leucinodes from Africa into other continents will need to be re-investigated for their species identity and will likely require, at least in parts, revisions of the quarantine regulations. The following African taxa are excluded from Leucinodes: Hyperanalyta Strand, 1918, syn. rev. as revised synonym of Analyta Lederer, 1863; Analytaapicalis (Hampson, 1896), comb. n. (Leucinodes); Lygropiaaureomarginalis (Gaede, 1916), comb. n. (Leucinodes); Sylleptehemichionalis Mabille, 1900, comb. rev., Sylleptehemichionalisidalis Viette, 1958, comb. rev. and Sylleptevagans (Tutt, 1890), comb. n. (Aphytoceros). Deanolisiriocapna (Meyrick, 1938), comb. n. from Indonesia is originally described and misplaced in Sceliodes, and Leucinodescordalis (Doubleday, 1843), comb. n. (Margaritia) from New Zealand, Leucinodesraondry (Viette, 1981), comb. n. (Daraba) from Madagascar as well as Leucinodesgrisealis (Kenrick, 1912), comb. n. (Sceliodes) from New Guinea are transferred from Sceliodes to Leucinodes. While Leucinodes is now revised from Africa, it still needs further revision in Asia.

Introduction

Guenée, 1854, the eggplant fruit and shoot borer, is a species of moth that was first described from specimens from India and Java (Guenée 1854). According to current knowledge, it is widely distributed in tropical and subtropical Asia (CABI 2012a) and sub-Saharan Africa (Walker 1859, Frempong 1979, CABI 2012a). The larvae are pests of , especially L. (aubergine, eggplant or brinjal) fruits and stems where they feed internally. Their infestation can substantially reduce yields from aubergine cultivation, and yield losses of more than 65% have been recorded from Asia (EPPO 2008).

The larvae are commonly moved in international trade with plants and fruits, as their internal feeding and the resulting damage may not be visible during pre-export inspections. Thus, is a quarantine pest of concern to a number of countries outside its native range. This includes the member countries of the European and Mediterranean Plant Protection Organisation (EPPO), where it was recommended as an addition to the alert list of pests in 2008 (EPPO 2008), and in 2012 transferred to the A1 list of pests recommended for statutory regulation (EPPO 2012, 2013). It is an A1 pest for several South American countries including Uruguay and Argentina (COSAVE 2006) and has repeatedly been intercepted in the USA (Whittle and Ferguson 1987, Solis 1999, 2006). In England and Wales, the Plant Health and Seeds Inspectorate (PHSI) regularly intercept Guenée, 1854 larvae inside aubergines from South Asia and West Africa (The Food and Environment Research Agency (Fera), unpublished data).

Due to the economic impact of PageBreak, the development of a genetically modified eggplant was initiated in 2005 in India by introducing a crystal protein gene (Cry1Ac) from the bacterium Berliner, 1915 (Bt) into the plant (Sood 2012). The insecticidal effect of the crystal proteins makes eggplant less susceptible to infestations by larvae of . After field trials and approval for commercial cultivation from government scientists in 2009, a moratorium on the commercialisation of Bt brinjal was imposed due to public concerns on food safety (Pandey 2010).

Until recently, all pyraloid larvae damaging fruits in Asia and Africa and intercepted from imports to Europe have been regarded as two species, and (Walker, 1859). Hayden et al. (2013) and Gilligan and Passoa (2014) pointed out that is restricted to Asia and that there are "three species in the complex in Africa that are not conspecific with the Asian species. Our investigations reveal that an even largernumber of species are intercepted from Africa. This points to the question of the identity of the intercepted species as well as on further four species of known from Africa, Gaede, 1916, (Mabille, 1900), Gaede, 1917 and (Tutt, 1890) (Nuss et al. 2003–2014). Besides , there is the similar genus Guenée, 1854, of which (Doubleday, 1843) and (Walker, 1859) are also pests on solanaceous crops in Australia (Davis 1964), New Zealand (Martin 2010) and Africa (CABI 2012b).

Here we taxonomically revise and and their species from continental sub-Saharan Africa, in order to delimit species and to allow their proper identification.

Larvae were sourced through quarantine interceptions of eggplant fruit from Africa and Asia at several ports of entry in England. Most larvae were studied alive and subsequently reared to adults in order to confirm the species identity. In large containments a few larvae were preserved by boiling them in water for 30–90 seconds, then transferred to 70% ethanol. After 3–5 days, the ethanol was replaced to limit dilution from body contents. Reared adults were killed soon after emergence, with cyanide, ammonia or by PageBreakfreezing at -20 °C for a minimum of 2 hours. Field-collected adults were attracted by artificial light and killed with cyanide. All adult specimens were subsequently pinned. Genital dissections of thoroughly dried specimens were performed according to Robinson (1976). Setal nomenclature follows Hinton (1946). The chaetotaxic descriptions and the setal map focus on those microscopic setae visible at 60 × magnification.

DNA was extracted using either the NucleoSpin tissue kit (Macherey-Nagel) according to the manufacturer’s instructions or using the Chelex-100 resin based method (Boonham et al. 2002). DNA extraction with the NucleoSpin tissue kit was performed following the procedure of Knölke et al. (2005), extracting DNA from the abdomen of adult specimens and subsequent dissection of the genitalia from the macerated abdomen. Extracted abdomina were stored in 70% ethanol until genitalia were dissected. For the Chelex-100 resin based method single legs or wings were removed from dried, pinned specimens using fine forceps and placed in individual 0.6 ml Eppendorf tubes. Briefly, 100 µl molecular-grade water was added to the tissue sample and ground using a micropestle. 100 µl of a 50% w/v chelex resin:water slurry was added, the sample heated to 95 °C for 5 minutes, centrifuged for 5 minutes and the supernatant transferred and stored at -20 °C prior to use.

PCR of the 5’ half of the cytochrome C oxidase subunit I (COI) gene, the so-called DNA Barcode (for Metazoa), was performed using primers HybLCO (Folmer et al. 1994, Wahlberg and Wheat 2008) and HybNancy (Wahlberg and Wheat 2008). For degraded material primer pairs HybLCO/K699 and Ron/HybNancy (Wahlberg and Wheat 2008) were used to amplify the COI Barcode in two fragments. PCR was performed in 25 µl reactions comprising 0.4u BIO-X-ACT Short DNA Polymerase (Bioline), 2.5 µl 10×OptiBuffer, 1.5 mM MgCl2, 200 nM each primer, 200 nM dNTP mix and 1–2 µl DNA (concentration as extracted). Cycling conditions were as follows: initial denaturation for 5min at 95 °C, 40 cycles with 1) 30 sec at 95 °C, 2) 30 sec at 48 °C, 3) 90 sec (HybLCO/HybNancy) or 60 sec (primers for degraded material) at 70 °C, final extension of 10 min at 70 °C. Alternatively primers LepF and LepR (Hajibabaei et al. 2006) were used in 25 µl PCR reactions using BIO-X-ACT Short 2× mix (Bioline), 400 nM each primer and 1–2 µl DNA (concentration as extracted). Cycling conditions were as follows: initial denaturation for 5 min at 94 °C, 35 cycles with 1) 30 sec at 94 °C, 2) 45 sec at 50 °C, 3) 1min at 72 °C, final extension of 10 min at 72 °C.

PCR products were visualised by separation in 1–1.5% agarose gels in 1 × TBE buffer (89 mM Tris-borate 2 mM EDTA) containing GelRed or ethidium bromide and visualised under UV light. PCR amplicons were cleaned up using ExoSAP-IT (Affymetrix) or QIAquick PCR purification kit (QIAGEN). Sequencing of both strands was performed by Eurofins MWG Operon (Germany) or in-house as follows. Sequencing PCRs were performed with BigDye Terminator v3.1 cycle sequencing kit (Applied Biosystems) using 5pm of the sequencing primer tails T7/T3 (Wahlberg and Wheat 2008) and 0.5–4 µl PCR product. Final clean-up was done via sodium acetate-ethanol precipitation. Sequencing was performed on a 3130 Genetic Analyzer (Applied Biosystems). PCRs, PCR clean-up and sequencing PCRs were performed on a Mastercycler ep gradient S (Eppendorf) or GeneAmp9700 (Applied Biosystems).

Obtained DNA sequences were proofread by eye and aligned using PhyDE 0.9971 (Müller et al. 2008) or MEGA version 4.1 (Tamura et al. 2007). Ambiguous PageBreakBarcode nucleotides were coded according to the IUPAC Ambiguity Code (Cornish-Bowden 1985). Sequences were then checked for plausibility using BLAST with the blastn algorithm (Altschul et al. 1990; URL: http://blast.ncbi.nlm.nih.gov/Blast.cgi) as well as the BOLD Identification System (IDS, URL: http://www.boldsystems.org/index.php/IDS_OpenIdEngine). A 615 basepair fragment was analyzed with MEGA version 6 (Tamura et al. 2013), using the distance criterion and the Neighbor Joining (NJ) algorithm (Saitou and Nei 1987) with uncorrected p-distances (Srivathsan and Meier 2011). Statistical support was evaluated through 1,000 Bootstrap replicates. (Hübner, 1796) was used to root the NJ tree.

We apply the morphospecies concept to our study. The DNA Barcode is used as additional source of information and as an identification tool for all developmental stages of African species. The species names mentioned in this study refer to their former context and do not necessarily correspond to the revised taxonomy by Knapp et al. (2013).

Label data of studied specimens were compiled in order to generate a distribution map. Geographical coordinates, if not given on the label, were obtained via Google Earth, Version 5.2.1.1588 and subsequently plotted on a map using DIVA-GIS, Version 7.2.3 (Hijmans et al. 2004).

Larva. Last instar larvae with pink dorsal integument, intersegmental areas cream or light pink, the ventral integument cream; strength of the colouration very variable, pink colour on majority of abdominal segments often interrupted laterally by a transverse cream line; head, prothoracic and anal shields mid brown with variable black markings; early instar larvae white or cream with brown pinacula and black head, prothoracic and anal shields.

The chaetotaxy of the thorax and first nine abdominal segments of the last instar is illustrated in Fig. 35. The relative size of pinacula and positions of setae are very variable intraspecifically. The head is mid to light brown, with variable black markings around ocelli and at genal angle; relative positions of cranial setae very unstable in the specimens examined. The prothoracic shield is light to dark brown with pale median sulcus and two variable dark markings: one along part of the posterior margin, strongest medially, and the other mediolaterally; usually additional darker spots bordering the median sulcus and extending laterally, spots very variable in extent and position; prothoracic L pinaculum crescent shaped with variable posterior extension, L setae anterior to the spiracle, usually vertically aligned; microscopic seta MV3 clearly visible in most specimens, can be almost as prominent as the V seta; MV3 setae share a mid-ventral pinaculum or are on separate pinacula; meso- and metathorax with clearly visible dorsal and subdorsal microscopic pinacula at 60 × magnification; three ventral microscopic setae less prominent, with MV3 usually being the least evident, these with or without small pinacula.

Remarks.

and have traditionally been distinguished by their forewing ground colour, which is predominantly orange-brown to greyish-brown in and white translucent in . The newly discovered sp. n. is intermediate in this character whereas all other wing pattern elements are homologous among and species. Study of the genitalia showed that cornuti are present in species, but are absent in , including . The female genitalia contain oval to semicircular sclerites in the lateral antrum pockets of , African and , the type-species of , which is distributed in Australia and New Zealand. Thus, there is a continuous variation between and and we here synonymise syn. n. with . As and have been published on the same date and in the same work, we here give precedence to as it is the better known of the two names, acting as first reviser according to ICZN 24.2.2.

Wing pattern indistinguishable from those of sp. n., sp. n., sp. n., sp. n. and “ spp.”, but distinguished from by the absence of the forewing basal transversal streak and the presence of the apical half moon-shaped patch, and from , and sp. n. by the predominantly white forewing ground colour. Frons usually more strongly bulged than in other species, but can be very similar in this feature. In male genitalia distinguishable by: dorsal margin of valval sacculus concave; apical sclerotized sacculus process elongated cone-shaped and crossing with the similar-sized fibula (as in ); juxta slender, tapering (similar in and ); saccus of vinculum short, less prominent. Female genitalia: antrum only slightly bulged, exocuticula without sclerotized strip.

Head. As for the genus, with frons strongly bulged (Figs 11–12).

Thorax. As for the genus, with dorsal side brown.

Wings. Forewing length ♂ 8.5–10.5 m, ♀ 9.5–12.0 m; forewing ground colour white, basal area light- to dark brown, delimited by dark brown to grey antemedial line; median area with pale brown, faint proximal discoidal stigma; distal discoidal stigma pale brown, reaching from costa to forewing centre; central dorsum with prominent orange to dark brown L-shaped or triangular spot leading to forewing centre and often meeting with distal discoidal stigma; antemedial line sinuate, more or less distinct, but with prominent subcostal bulge; subapical half of termen with half moon-shaped brown to grey-grown spot; marginal line dotted; fringe and marginal line darkened at the tips of the half moon-shaped spot; hindwing ground colour white, internal area white, with discoidal spot, basicostally often with auxiliary spot; medial line sinuate, distal half approaching the discoidal spot, then turning towards dorsum; external area pale brown to gray; marginal line dotted.

Abdomen. First segment whitish, remainder brownish.

Male genitalia. As for the genus, apart from: juxta subulate, with short, broadly convex base, at 2/3 length slightly broadened; valvae broad, relatively short, nearly triangular; costa simple, slightly convex, subapically with a short concave portion; fibula hooked, its widened base emerging ventrad of costa base; sacculus ventrally convex, dorsally concave, at distal end with spike-shaped, strongly sclerotized process, oriented dorsad and crossing with fibula; distal ventral valva margin granulated (ga in Fig. 13), valva apex rounded, strongly granulated; distal 2/3 of ventral valva margin loosely covered with long thin setae; phallus simple, tapering posteriad, posterior apodeme dorsally elongate, ventrally with subapical, weakly serrated sclerite; ventral and dorsal portion of posterior apodeme separated by a slim, less strongly sclerotized region.

Female genitalia. As for the genus, apart from: anterior antrum with spoon-shaped posteriad indentation, flanked on either side by a sclerotized portion (as in Fig. 31); sternite 8 anterior edge arched (ae in Fig. 31), with a sclerite process leading in each of the lateral pockets; both apophysis pairs simple, slightly curved.

Larva. MSD1 and MSD2 of meso- and metathorax usually on a shared pinaculum, earlier instars frequently have the MSD setae on separate pinacula on one or both segments; dorsal abdominal pinacula show apparent differentiation between West- and East-Asian populations: in live western specimens (e.g., from Pakistan), the abdominal D1 pinacula usually have an unpigmented cream coloured area near to their anteriomedian margin. This unpigmented area may be contiguous with the unmelanized cuticle surrounding the pinaculum or be surrounded by the melanized cuticle of the pinaculum (illustrated on A3–6 in Fig. 35); this cream white, unpigmented area may darken in preserved specimens, and in pre-pupae may be ringed in black. Eastern specimens (e.g., from Thailand) often have dark spots on at least some of the D1 pinacula (illustrated on A2 in Fig. 35); geographically intermediate populations (e.g., Sri Lanka) often show an intermediate form with black spots on occasional pinacula, and any unpigmented area is PageBreakusually ringed with black pigmentation (illustrated on A7 in Fig. 35). East-Asian populations usually have mesally triordinal crochets, whereas the crochets of West-Asian populations are mesally biordinal. Pupa. Cremaster forms a variable shelf-like, sub-rectangular structure, much wider than long, usually with distinct distal corners and median notch; dorsal surface spinulose, with additional small but distinct spines which are variable in extent, form and number; cocoon of dark brown silk, may be white or beige when newly spun.

Female genitalia. As for the genus, apart from: anterior antrum with tubular sclerotized exocuticle; sclerotized wall at antero-ventral edge of the ostium bursae which at rest closes the ostium bursae against abdominal segment 8. This wall is not melanized and can be stained with chlorazol black. It is delimited dorso-laterally by sclerotized and melanized lobes arising from the anterior edge of segment 8 just ventral of the apophyses anteriores. Anterior to the sclerotized wall there is a small, melanized colliculum.

The species is named after Kenya, the only country from where it is confidently recorded so far.

So far only known from Kenya. The record from Zimbabwe needs confirmation by investigation of female specimens and molecular analysis.

Distinguished from most other members of by the orange-brown to greyish forewing colour. Distinguished from by the generally darker forewing colour with less amount of white. Differs from both and in: male genitalia with large, oval sacculus; broad, strongly sclerotized ventrad fibula; saccus well elongated; phallus coecum keeled, posteriodorsal apodeme with slim, fingerlike, well sclerotized process; female genitalia with antrum broad, its anterior end coiled, with exocuticle diffusely sclerotized.

Head. Frons slightly bulged; labial palps upturned, greyish to brown, first meron on ventral side with forward-directed tuft, third meron in males half as long as second meron, considerably longer in females; maxillary palps minute; haustellum well developed; eyes large, hemispherical; ocelli present; antennae ciliate, cilia considerably longer in males; vertex with creamy white scales; chaetosemata absent.

Thorax. Dorsal side brown with greyish and dark brown scales mixed in; ventral side grey to whitish; legs predominantly whitish or grey, epiphysis present; tibial spurs 0, 2, 4 with outer spur 2/3 the length of inner spur.

Wings. Forewing length 7.0–11.5 mm, the females being somewhat larger; both sexes with one frenular bristle; forewing ground colour orange- to grey-brown, with the general wing pattern.

Abdomen. First segment whitish, remainder light-brown; older specimens often with darkened abdomen due to degeneration of abdominal fat body.

Male genitalia. As for the genus, apart from: vinculum saccus conspicuously elongated anteriad; juxta usually with small notch at median base; valvae emerging in narrow angle from vinculum; phallus with keeled coecum, posteriodorsal apodeme with slim, fingerlike, slightly curved and well sclerotized process, vesica with a short line of tiny cornuti.

In Africa known from Côte d’Ivoire, Ghana, Kenya, Morocco, Nigeria, Senegal, South Africa, Tanzania (own observations). Externally, is similar to (see below), therefore literature records from other African countries than those listed here need verification. In Europe recorded from Spain, Portugal (Speidel 1996, Huertas Dionisio 2000; own observations) and Great Britain (own observations). The records from Great Britain certainly refer to interceptions and it is assumed that those from the Iberian Penninsula also do not refer to a native occurrence. Huertas Dionisio (2000) recorded the species from , a species native to southern Africa.

Larva. Generally very similar to PageBreak and . On the metathorax the MSD setae are usually on separate pinacula, while the mesothoracic MSD setae are usually on the same pinaculum. The abdominal D1 pinacula are often smaller than those of and , and lack dark spots or unpigmented areas (see Ogunwolu (1978) for a detailed larval description and chaetotaxy). Pupa. length ca. 8.5 mm; distal margins of cremaster usually evenly rounded, without distinct corners; spinulation of cremaster’s dorsal surface a little coarser than dorsal spinulation on abdominal segment 9 dorsal surface, no distinct small spines as in or ; cocoon of beige coloured silk that does not darken significantly over time.

We found a significant DNA Barcode difference of 2.4–2.8% uncorrected-p distance between the single South African specimen and the Kenyan and Ghanan/Nigerian Barcode clusters (Fig. 47; see also section ‘DNA Barcoding’ below). These differences in the DNA Barcode are not reflected in a divergent morphology of the clusters.

The record of from Belgium by Nyst (2004) is most probably a misidentification, since the illustrated imago resembles much more the whitish species. Apart from that, there is a European record of from Spain. Additionally, it is frequently intercepted with the import of solanaceous fruits in Great Britain.

Despite repeated search in the collection of the ZMHB, original material of Gaede, 1917 from Tanzania, Tendaguru, could not be traced. According to the original description, this taxon can be regarded as conspecific with due to all details given in the original description. Especially the white triangle at the anterior line, another white triangle, though often somewhat inconspicuous, at the middle of costa, and the dark brown area below apex support the conspecifity with .

This species was described in PageBreak Walker, 1859, a genus that has previously been synonymised with Guenée, 1854 by Hampson (1899). The type specimen of (Viette, 1981), comb. n. from Madagascar could not be traced at MNHN. According to the original description and the illustration of the species given therein (Viette 1981), this species agrees with the diagnostic wing pattern elements of , and we therefore consider it as correctly placed in this genus. It differs from in the larger size, the more ochreous grey tone and the reduced half moon-shaped subapical patch of the forewings (Viette 1981). None of the species described here as new have the prominent dark subapical patch in the hindwings of , so that conspecifity with any of them can be ruled out.

The wing pattern of Meyrick, 1938 exhibits none of the features found in . Instead, the fore wings are pale yellow, with a yellowish costa, a dark spot in both outer edges of the cell, and a reddish undulating margin along the termen. The hind wings are of the same pale yellow ground colour, and the anterior half of the termen exhibits a similar margin as found in the fore wings. This wing pattern is common to the genus Snellen, 1899, where this species is correctly placed (pers. comm. James E. Hayden).

Discussion

The investigation of the species from sub-Saharan Africa reveals a new picture on the taxonomy of the fruit feeders. Instead of one widely distributed species in Asia and Africa, there is an endemic species complex in Africa and is restricted to Asia, corroborating the statement by Hayden et al. (2013). Among the African species, and are widely distributed on the continent, whereas , , and seem to have a rather restricted range. is only known from one specimen from Malawi. These data may indicate different, though partly overlapping patterns of distribution as seen in Fig. 48, but this is still an incomplete dataset, resulting in fragmentary distribution patterns for and . The possibility of transport by man also has to be taken into consideration.

Figure 48.

Distribution map of African species.

Food plant data are only available for , , , and (Table 2). While is known to feed on a variety of cultivated and non-cultivated , the other four species are known from cultivated only. This may rather refer to a bias of investigation, which so far has concentrated on fruits of economic importance. In nature, the species may have different host plants to which they were originally adapted. Those wild hosts may also have certain areas of origin. Such a scenario has to be expected, considering the fact that several species of have evolved in Africa. Some of these species might be restricted to their wild host plants and unable to switch to other, cultivated species. In contrast, species able to adapt to cultivated might be transported with fruits in trade, resulting in a larger range within Africa.

After movement of larvae with fruits in African trade, they may be more frequently intercepted by trade with those fruits into other continents. Most imports of PageBreak specimens from Africa into Europe refer to , which has been frequently imported with fruits during the last 50 years. In contrast, has been much less frequently recorded, and as well as only very recently in fruit imports from Uganda. Since our investigations show that does not occur in Africa, interceptions of from Africa into other continents will need to be re-investigated for their species identity and will likely require, at least in parts, revisions of the quarantine regulations. Furthermore, if species are transported in trade, it has to be considered that species of and related South American genera, e.g. Capps, 1948, and , might also become introduced from one to another of the southern continents.

Analysis of the COI gene of the species demonstrated that interspecific differences allow the use of the marker as a DNA barcode for species identification. However, for and “ spp.”, we found little morphological differences but two distinct barcode species within spp. Moreover, we observed high intraspecific divergence in with one specimen from South Africa exhibiting a COI distance of 2.8%.

Outside Africa, the taxonomy and phylogeny of PageBreak requires further research. The characteristic forewing pattern elements of the Old World is also found in the New World genera , and , all described by Capps (1948). In male genitalia, is distinguished from these three genera by the absence of cornuti in the phallus, from and also by the presence of a fibula, and further from by the dorsal location of the uncus spines. In female genitalia, is distinguished from by the presence of lateral antrum pockets (condition unknown in ), but cannot be clearly distinguished from , in which antrum pockets can be absent (e.g., (Guenée, 1854)) or present ( (Dyar, 1914), Capps, 1948), and pocket sclerites can be absent (e.g., ) or present ( (Guenée, 1854), ). Whether these differences refer to a typological classification or justify the maintenance of the current generic classification needs to be investigated by phylogenetic analysis.

For Austral-Asia, there remain twelve nominal species (Nuss et al. 2003–2014). Other than , at least some of these species are certainly misplaced in , e.g. Swinhoe, 1904 from Borneo and Caradja, 1933 from China. Therefore, the Asian are in need of taxonomic revision. This also points to the question whether all samples intercepted from Asian exports refer to , or whether there are several species of economic importance in Asia as well (Hayden et al. 2013, Chang et al. 2014, Gilligan and Passoa 2014).

Our work contributes to the identification of African species, based on adult characters and on DNA Barcodes, by which also the immature stages can be efficiently distinguished. This may help to systematically survey the continent for distribution of species, in order to discover their wild host plants and their movements in trade. At this stage of knowledge it wouldn’t be a surprise to discover additional, still unknown species. The results of our completely revised taxonomy of African suggests that a revision of the EPPO A1 List of pests recommended for regulation as quarantine pests (EPPO 2013) will be necessary. During the period from 2004 to 2007, 121 interceptions of fruits infested by were recorded by several EPPO member countries. The majority (94 consignments) originated from Thailand, Ghana accounted for 18 infested consignments (EPPO 2008). is also ranked as quarantine species important for the USA, but specimens intercepted from Africa cannot be , as stated by Hayden et al. (2013) and Gilligan and Passoa (2014) and as shown by our results. The USA has recorded 1745 interceptions from Ghana to the USA between 1985 and 2004 (Boateng et al. 2005).

Conclusion

A careful revision of PageBreak in sub-Saharan Africa resulted in the new synonymy of the genus syn. n., the revised synonymy of with , the transfer of four species to , the description of seven new species, the new synonymy of one species, the omission of the type species from the African list and the generic transfer of five species found to be misplaced in . Of the eight species recognized from Africa now, at least four are frequently intercepted among imports of solanaceous fruits at European ports of entry. We provide the DNA Barcode for these four and two additional African species, allowing the identification of all life stages of these species.

Our work shows that typological concepts of taxonomy based on superficial similarity were still the state of the art in the genus . The discovery of a complex of highly similar species demonstrates that traditional morphological methods and DNA Barcoding are helpful tools to detect species diversity and to improve their classification based on sound arguments.

Similar revisionary work remains to be done for Austral-Asian . A phylogenetic study including and the New World , and is needed in order to test the monophyly of these genera (Hayden and Mally, in prep.).

3*	Fibula small, strongly sclerotized, emerging near ventral valva edge; sacculus less than half the length of valva; saccus elongated, tip not pointed; ventral posterior phallus apodeme with slim, posterioventrally protruding, well sclerotized process	Leucinodes malawiensis sp. n.
4	Distal sacculus process projecting towards valva apex, straight or apically hooked, sometimes branching, apex dentate; juxta subulate; posterior phallus apodeme with oval saw blade-shaped sclerotization	5
4*	Distal sacculus process tooth- or hook-like; juxta much broader; posterior phallus apodeme without oval saw blade-shaped sclerotization	6
5	Valva apex rounded; ventrad fibula stout, with broad base, straight or slightly curved; distal sacculus process hook-shaped, not branching, spanning ≤ half the distance fibula base–valva apex	Leucinodes rimavallis sp. n.
5*	Valva apex pointed; ventrad fibula slender, with narrower base, curved; distal sacculus process straight or hook-shaped, sometimes branching, spanning > half the distance fibula base–valva apex	Leucinodes africensis sp. n.
6	Dorsad fibula conical and smaller than distal sacculus process, which is large, hook-like and arching above fibula	Leucinodes kenyensis sp. n.
6*	Dorsad fibula and fibula-like sacculus process being roughly of same shape and size and running parallel or crossing each other	7
7	Fibula and fibula-like sacculus process large, spanning almost the entire valva transversally; ventral valva edge not straight but with arch dorsal of fibula and fibula-like process; posterior phallus apodeme ventrally with oval sclerite	Leucinodes pseudorbonalis sp. n.
7*	Fibula and fibula-like sacculus process small, barely reaching the valva centre; ventral valva edge more or less straight; posterior phallus apodeme without oval sclerite	Leucinodes ugandensis sp. n.
