Rove beetle subtribes Quediina, Amblyopinina and Tanygnathinina: systematic changes affecting Central European fauna (Coleoptera, Staphylinidae, Staphylinini).

In preparation for the new edition of the identification keys of rove beetles of Central Europe (Volume 4 of the "Die Käfer Mitteleuropas"), the following systematic problems affecting the Central European fauna of the tribe Staphylinini are addressed: phylogeny-based, new concepts for the subtribes Quediina and Amblyopinina; status of the subtribe Tanygnathinina; systematic position of the genus Astrapaeus; status of Quedionuchus, the subgenus of Quedius; identity of some species of Quedius and Heterothops. As a result, new wordwide and Central Europe-based diagnoses are given for the subtribes Quediina and Amblyopinina; earlier recognized but not widely accepted synonymies of the genera Quedius and Velleius, and of the species Heterothops praevius and Heterothops niger, are justified; new synonyms are established for: Quedius pseudonigriceps Reitter, 1909 (= Quediusnoricus Bernhauer, 1927, syn. n.); Quedius maurorufus (Gravenhorst, 1806) (= Quedius richteri Korge, 1966, syn. n.); Quedius suturalis Kiesenwetter, 1845 (= Quedius merlini Drugmand & Bruge 1991, syn. n.); lectotypes are designated for Quedius meridiocarpathicus Smetana, 1958, Quedius noricus Bernhauer, 1927, and Quedius pseudonigriceps Reitter, 1909. As a result of synonymy of Quedius and Velleius, the following new combinations are proposed: Quedius amamiensis (Watanabe, 1990), comb. n.; Quedius circumipectus (Cho, 1996), comb. n.; Quedius elongatus (Naomi, 1986), comb. n.; Quedius japonicus (Watanabe, 1990), comb. n.; Quedius pectinatus (Sharp, 1874), comb. n.; Quedius setosus (Sharp, 1889), comb. n.; Quedius simillimus (Fairmaire, 1891), comb. n. As a result of new combinations, Quedius japonicus (Watanabe, 1990) (non Quedius japonicus Sharp, 1874) is replaced with the new name Quedius watanabei Solodovnikov, nom. n., while Quedius pectinatus Lea, 1908 (non Quedius pectinatus (Sharp, 1874)) is replaced with the new name Quedius arthuri Solodovnikov, nom. n.

Introduction

Central Europe (territories of Denmark, Germany, Poland, Benelux-states, Austria, Czech Republic, Slovakia and Switzerland) is a conventional area that has no integrity in terms of biogeography. But since this region has a strong common entomological tradition, the insect fauna of Central Europe is often viewed as such despite not being cohesive either zoogeographically or phylogenetically. Currently it is perhaps the best known entomofauna in the world as far as any other territory of comparable size is concerned. At least this is true for the beetle family Staphylinidae covered in the milestone volumes 4 and 5 of the well-known series “Die Käfer Mitteleuropas”. In the course of time however, the inevitable obsolescence of these reference books necessitates new editions. Gladly, a new version of the Volume 4 (Lohse 1964) was recently accomplished by an international team of authors led by German colleagues Volker Assing (Hannover) and Michael Schülke (Berlin) (Assing and Schülke 2012).

Being involved in that project as an author of the sections equivalent to “Quediini” and “Atanygnathinini” (Staphylininae) in Lohse (1964), I came across a necessity of publishing some formal taxonomic changes for the Central European fauna to be used in Assing and Schülke (2012). Also, some earlier published world-wide systematic work on Staphylinini (Solodovnikov and Newton 2005; Solodovnikov 2005, 2006; Solodovnikov and Schomann 2009; Chatzimanolis et al. 2010) that affected the Central European fauna, needed a concise digest specifically targeting a European user. All these issues are addressed in the present paper, and grouped in the following three categories: subtribal classification of Staphylinini; -complex; and species-level problems in and .

Subtribal classification of Staphylinini

With more than 200 genera and more than 5,000 species worldwide, Staphylinini is one of the largest tribes of rove beetles. As mentioned in recent works (e.g., Smetana and Davies 2000; Solodovnikov 2006; Solodovnikov and Schomann 2009; Chatzimanolis et al. 2010), the supra-generic classification of Staphylinini currently in use (e.g., Herman 2001; Newton and Thayer 2005; Bouchard et al. 2011) needs modification. Although many aspects of the phylogeny of Staphylinini are still unclear, certain parts of it are already resolved and translated into a classification. Some aspects affecting the fauna of Central Europe are summarized here.

On the systematic position of the genus Gravenhorst, 1802

Both morphology- and molecular-based analyses, no matter how they disagree in detail, place certain members of the conventional subtribe “Quediina” (genera Solodovnikov, 2006, Astrapeus Gravenhorst, 1802, Parisanopus Brèthes, 1900 and Smetana, 1981) as basal lineages of Staphylinini (see for example fig. 6 in Solodovnikov 2006, fig. 1 in Solodovnikov and Schomann 2009; and fig. 1 in Chatzimanolis et al. 2010). These genera are species-poor and have narrow distributions scattered around the globe, such evidence also suggesting their ancient, relict nature among Staphylinini. Contrary to the formal classification where they are placed in the subtribe Quediina, neither of them form a monophyletic group with the “core” clade of “ (the monophyletic part of the conventional Quediina hosting the type species of ; e.g, the clade marked in red in fig. 1 in Solodovnikov and Schomann 2009). To balance the formal classification of Staphylinini with the underlying phylogeny, a series of monobasic supra-generic groups (possibly subtribes) has to be erected for those isolated basal genera. However, to avoid premature creation of several new family-group names when the phylogeny of the entire Staphylinini is not stabilized yet, Chatzimanolis et al. (2010, table 1) classified such genera as incertae sedis within Staphylinini. Since is the only genus in Central Europe that falls in this category, and the European authors are used to its placement in Quediina, the species ulmi (Rossi, 1790) is still listed as a member of that subtribe in the new edition of the “Die Käfer Mitteleuropas” (Assing and Schülke 2012). Unlike the specialized phylogenetic paper of Chatzimanolis et al. (2010), the keys to Central European fauna is a practical tool, limited geographically, but targeting a very broad scope of users with varying taxonomic background. Therefore, for those keys, the exact and familiar classification of a phylogenetically unstable taxon seems a more useful PageBreaksolution, as opposed to its uncertain position, even though the latter may reflect the current phylogenetic knowledge more accurately.

New limits and diagnosis of the subtribe Quediina Kraatz, 1857

Similarly to basal groups like , some other genera across Staphylinini display “-like” habitus. That similarity is mostly caused by their deflexed hypomera of pronotum and variously shaped “infraorbital ridges” (the latter often combine non-homologous structures, as discussed in Solodovnikov 2006). The “-like” habitus of unrelated Staphylinini misled systematists who gradually inflated Quediina to a largely polyphyletic taxon. Contrary to the currently accepted classification but according to the abovementioned new phylogenetic data, the limits of the subtribe Quediina should be restricted to the north temperate Holarctic core of the current genus , plus some other, mostly Holarctic, smaller genera of the traditional “Quediina”. An example of Quediina in such new definition is marked by red in fig. 1 in Solodovnikov and Schomann (2009), while the entire list of genera of the newly defined subtribe Quediina is provided in the table 1 in Chatzimanolis et al. (2010). Within the Central European fauna all species of the genus (including as a synonym of , seebelow), as well as genera and , belong to Quediina in the newly defined sense. But the genus that also occurs in Central Europe and that traditionally stayed in the subtribe “Quediina”, however, belongs to the subtribe Amblyopinina, also in a newly defined sense (see below). To accommodate these changes, new global and regional diagnoses of Quediina are here provided.

. Small to medium size beetles with pronotum having deflexed hypomera and thus not visible in lateral view; head with well-developed infraorbital ridges (as defined in Smetana and Davies 2000) extending from neck towards base of mandibles and often reaching the latter; tarsal formula 5-5-5; mesoscutellum with two basal carinae (in normal position that part of mesoscutellum is hidden under base of pronotum); aedeagus of variable shape, but with paramere never very closely attached or fused to median lobe, mostly with distinct, heavily sclerotized sensory peg setae.

Except a few (mostly montane) species extending into (sub)tropical latitudes of the Oriental and Neotropical regions, and some adventive species that occur nearly world-wide, the group is restricted to the north temperate zone of the Holarctic region and is markedly absent in the Sub-Saharan Africa. Many Quediina are confined to leaf litter of the north temperate forests, some also occur in ground-based debris of various open landscapes.

. Small to medium size beetles; head with well-developed infraorbital ridges; pronotum with deflexed hypomera and thus not visible in lateral view, on disc with 2–4 punctures in dorsal rows; tarsal formula 5-5-5; apical segment of maxillary and labial palps never very narrow or aciculate, mostly (but not always) fusiform with more or less truncate apex; aedeagus with well developed paramere that is separated from the median lobe along most of its length, mostly with sensory peg setae.PageBreak

New limits and diagnosis of the subtribe Amblyopinina Seevers, 1944

Along with the new definition of Quediina, the mentioned phylogenetic studies reveal an earlier unrecognized monophyletic lineage that consists of: some south temperate genera of Staphylinini most of which were in the conventional subtribe “Quediina” (for their list see table 1 in Chatzimanolis et al. 2010); many Staphylinini species from Australia and New Zealand currently misplaced in the genus (e.g., represented by Lea, 1929 in the analysis of Solodovnikov and Schomann 2009); and several genera of truly remarkable staphylinids from South America and Australia (members of the subtribe Amblyopinina Seevers 1944 in the conventional system, e.g., Herman 2001). As far as the Central European fauna is concerned, it is only the genus (globally distributed, poorly defined genus, for details see Solodovnikov and Schomann 2009) that belongs to this lineage. Since Amblyopinina Seevers, 1944 is the oldest available family-group name for this newly found large monophyletic lineage, its meaning has to be expanded far beyond the initial scope that included only highly specialized “very exotic” Neotropical and Australian symbionts of small mammals. The strongly modified morphology of the latter is an adaptation to a very special habitat like the fur of a mammal body; such strong autapomorhy simply disguised sister relationships of these beetles for decades. Moreover, it is apparent that the symbiosis with mammals and associated specialized morphology may have originated independently in several lineages of free living “usual -like” south temperate Amblyopinina (Ashe and Timm 1988). Following the discussed phylogenetic results, and in agreement with the here provided new diagnosis of Amblyopinina in Assing and Schülke (2012), is treated used in the subtribe Amblyopinina, not in Quediina.

. Small to medium size beetles with pronotum having deflexed hypomera and thus not visible in lateral view; tarsal formula 5-5-5; mesoscutellum with one basal carina (in normal position that part of mesoscutellum is hidden under base of pronotum); aedeagus: paramere longer than, and closely attached to, median lobe; often median lobe relatively poorly developed or, in the ultimate case of , reduced and entirely fused to strongly developed paramere.

Except the global genus , the group is restricted to the southern hemisphere, and is especially species-rich and abundant in leaf and log litter of the south temperate and subtropical forests of southern South America, Australia, New Zealand, and less so in Papua New Guinea and New Caledonia. A few genera of Amblyopinina, possibly not closely related to each other, are symbionts of mammals and have peculiar “ectoparasitic” morphology.

. Small beetles with pronotum having deflexed hypomera not visible in lateral view, disc of pronotum with two punctures in dorsal row; tarsal formula 5-5-5; apical segment of maxillary and labial palps very narrow, aciculate, at base much narrower than their respective penultimate segments; aedeagus with median lobe reduced and entirely fused to strongly developed paramere.

Status of the subtribe Tanygnathinina Reitter, 1909

In connection with the discussion about Amblyopinina in the new sense, the systematic position of the genus Jakobson, 1909, represented in Central Europe by a single species (Erichson, 1839), should be also commented. Adult and larval morphology of is very peculiar (Solodovnikov 2005; Staniec 2005), but according to the morphology-based phylogenetic analyses (Solodovnikov 2006; Solodovnikov and Schomann 2009), these peculiarities apparently are autapomorphies, while the genus shares synapomorphies with the above discussed large south temperate lineage Amblyopinina. Contrary to morphology though, the molecular analysis (Chatzimanolis et al. 2010) did not support affiliation of with that group and, at the same time, did not suggest a plausible alternative placement. Conflicts among various datasets, especially as different as animal morphology and DNA-sequences, are not unusual in systematic biology. Given a very high impact of morphology on practical systematics, and instability of molecular phylogenies when they are based on few genes (as opposed to generally more robust multigene phylogenies), a morphology-based solution for the systematic placement of a taxon would have been given a priority over a conflicting hypothesis that is based on limited molecular dataset. But, as far as is concerned, there are two practical considerations against the placement of in Amblyopinina. Firstly, immediate acceptance of the morphology-based hypothesis would necessitate the synonymy of the family-group names Tanygnathinina Reitter, 1909 and Amblyopinina Seevers, 1944, where the former name would be valid due to its priority while being tied to the phylogenetically most unstable taxon. Secondly, the monobasic Tanygnathininacan be easily characterized and keyed out by striking autapomorphiesof : very elongate mouthparts and tarsal formula 5-4-4, both features unique among Staphylinini. Inclusion of into Amblyopinina, on the contrary, would diffuse the diagnosis of the latter subtribe. As a result, a separate monobasic subtribe Tanygnathinina is currently maintained for that genus, also in Assing and Schülke (2012).

–complex

One of the biggest systematic problems at the genus level within the tribe Staphylinini is the so-called “-complex” (Solodovnikov 2006). As it stands now (for example, Herman 2001; Newton and Thayer 2005), the genus is highly polyphyletic and lacks a consistent intrageneric division. Operational species groups in were defined only for some regional faunas like America North of Mexico, and parts of the Palearctic and Oriental regions, while the originally very inconsistent subgeneric division, although once improved by Smetana (1971) for the Holarctic fauna, still needs a rigorous phylogenetic and broader overview. As a result, there remains a plethora of genus-group taxa within and around , whose status remains controversial. With respect to Central European fauna, Sharp, 1884 and Leach, 1819 are such groups.PageBreak

On the status of Sharp, 1884

was originally established as a genus (Sharp 1884) (with the type species Solsky, 1868, designated by Blackwelder 1952). Eventually various European authors downgraded to a subgenus of and expanded its limits to include also some species of another subgenus of (Smetana 1971). Smetana (1971) corrected the volume of by removing members of from the former, but he left as a subgenus of . Analysis in Solodovnikov (2006) placed outside , suggesting that a separate generic status for the former would be a better solution. Because the formal reclassification of the “-complex”is pending a broader study, in Assing and Schülke (2012) the traditional subgeneric status of is maintained for practical reasons.

Synonymy of Stephens, 1829 and Leach, 1819

Leach (1819) described the genus to accommodate two species, dilatatus Fabricius, 1787 and Marsham, 1802 (currently a synonym of (F.)), the latter species subsequently (Westwood 1838) designated as a type species. Although all eight currently known species of (Herman 2001; Smetana 2004; new combinations below) share characteristic large size and pectinate antennae, doubts regarding a separate generic status for this group were expressed by a number of earlier authors who treated as a synonym of (e.g., Erichson 1839; Lacordaire 1854; Kraatz 1857; Schaum 1859). Also Smetana (1988) pointed out a case when it was difficult to assign a species, (Champion, 1925) (originally described as ), to either or , a subgenus of . The habitus, taxonomically important chaetotaxy and aedeagus of are essentially the same as in . The larva of is -like (Paulian 1941; Strassen 1957; Pototskaya 1967; data matrix in Pietrykowska-Tudruj et al. 2011). Molecular-based phylogenetic analysis (Chatzimanolis et al. 2010) also placed species of nested within (). Even a peculiar biology, known for (larvae of this species live in the nests of the European hornet (e.g., Strassen 1957)) is just a strongly expressed case of an overall evolutionary trend towards nidicoly seen in many other species of . Therefore, following some earlier authors, and should be considered as synonyms, that is also followed in Assing and Schülke (2012). Because is a much more species-rich and abundant genus than , in the interests of stability of the zoological nomenclature, an application to the International Committee for the Zoological Nomenclature has been prepared to suppress the Priority Rule and give precedence to the younger generic name Stephens, 1829 over the older generic name Leach, 1819. Since the species (F.) was used in the combination with the genus before, the following new combinations are here proposed: PageBreak (Watanabe, 1990), comb. n.; (Cho, 1996), comb. n.; (Naomi, 1986), comb. n.; (Watanabe, 1990), comb. n.; (Sharp, 1874), comb. n.; (Sharp, 1889), comb. n.; (Fairmaire, 1891), comb. n.To avoid the resulting homonyms, the name (Watanabe, 1990) (non Sharp, 1874) is replaced with the new name Solodovnikov, nom. n.,while the name Lea, 1908 (non (Sharp, 1874)) is replaced with the new name Solodovnikov, nom. n. New names are provided because neither of these two junior homonyms had available synonyms that could be valid names in new combinations.

Species-level problems in and

On the synonymy of Erichson, 1839 and Kraatz, 1868

Controversy over the status of and had begun soon after the publication of the original description of . Although already a few earlier authors considered as a synonym of (e.g., Fauvel 1874; Fowler 1888; Ganglbauer 1895; Porta 1907), a predominant approach was to treat the former either as a distinct species, or as some kind of the intraspecific form of . A long history of this controversy is summarized in Israelson (1979) and Lott (2008). Israelson (1979), based on the detailed morphological examination of specimens from Sweden and survey of the literature covering other regions, came to the conclusion that and differ slightly in the body coloration ( is paler, while is darker), distribution ( has broader distribution, while has narrower distribution within the range of ) and ecology ( is free living, while is nidicolous). Lott (2008), based on the morphological examination of British material, also came to the conclusion that (paler) and (darker) differ in coloration. However he denied the sharp ecological difference between these species defined as “free living versus nidicolous ”. Contrary to expectations, in his survey was found not only in free habitats but also in the badger setts, while was found only in the mole nests. Israelson (1979) proposed to consider as a subspecies of , that clearly was not a good decision for sympatric (and even syntopic) forms. Lott (2008) removed such inconsistency by stating that these sympatric taxa are two separate species, even though the morphological difference between them is very vague.

My examination of the abundant material identified by various people as both species from various parts of Denmark, and similar combined but sparser sample from various parts of Europe, reveals the following. Firstly, there is no such clear coloration difference (pale versus dark) as it was stated by Israelson (1979) or Lott (2008) for limited samples. Intermediately colored specimens that are hard to assign to either of these two (dark or pale) categories of coloration are not exceptional even among the Danish material alone. Secondly, consistently with Israelson (1979), there is no hiatus in a continuous variation of the structures of the aedeagus within the pool combining paler (presumable ) and darker (presumable ) specimens. Therefore there are no genitalic characters that would break a combined sample of the putative and into two or any other number of groups. Thus, no structural character supports the vague division between paler and darker specimens. With such a weak basis for morphological delineation of from , secondary data like ecology or distribution become unreliable, while a synonymy of and is considered a preferable solution that is followed in Assing and Schülke (2012).

Discussion

Smetana, 1958 is very similar to (Gravenhorst, 1906). Both species can be reliably distinguished only by the shape of their aedeagi (Figs 1–8) and mostly by the shape of the largest (C-like) sclerite of the internal sac (cf. Figs 2 and 6). External characters hitherto used for PageBreakseparation of these species (details of punctuation of the elytra and abdomen, slight difference in the proportions of the body parts), as well as details of the shape of the aedeagus are variable in both species. Since some specimens of in the collections are misidentified as and vice versa, the hitherto published distribution records for both of them (for a summary of literature see Herman 2001) in Central, Southern and Eastern Europe need revision. In fact, even the type series of includes one male specimen of , an ambiguity here eliminated by designation of the lectotype (see below). Based on the material which I have examined (listed above, and more), is reliably known from the south of Central and Eastern Europe, as well as from the Balkan Peninsula and Turkey.

Lectotype designation

The only information about the type material published in the original description of is that it was collected at “Kamenný most” and “Slanec” in southern Slovakia (Smetana 1958). Aleš Smetana kindly sent me 11 specimens as a type series of , all of them were collected by himself: 10 (4 males, 6 females) at Kamenný Most on 3.V.1955, and one male at Slanec in 1953. All these specimens are considered as syntypes. Of them, a single male from Slanec is undoubtedly , but all males from Kamenný Most belong to . Females from Kamenný Most are also identified as based on the association with the respective males. To avoid future ambiguity about the identity of one male from Kamenný Most is here designated as a lectotype of this species.PageBreak

Discussion.

was described from two females collected at “Hofgastein Tal Juli 1926 Bernhauer” [label data from two syntypes] in Austria (Bernhauer 1927). Coiffait (1963, 1978) included this species in his determination keys, provided its redescription and outlined its distribution as “Alpes orientales, montagnes d’Europe centrale” [Eastern Alps, mountains of Central Europe]. He provided illustrations of the aedeagus of this species based on the material from Chech Republic (“chaîne Bryb”). For some reason was not included in the keys to the Central European Staphylinidae (Lohse 1964), but it was added there later (Lohse 1989), based on the mentioned accounts of this species by Coiffait (1963, 1978). Horion’s (1965) brief account about was also based on the earlier published Bernhauer’s original description and data in Coiffait (1963) only. Additionally, based on the personal communications from Scheerpeltz and Korge, Horion (1965) mentioned some other specimens of from Estern Alps (“Bad Gastein, Leder leg., det. Bernhauer (i.l.) Badbruck (900 m) [here examined, see above] und Kötschental (1300 m): Bernhauer leg.; Kolm-Saigurn Käufel leg.”: material from Scheerpeltz’ collection), and from the southern part of Romania (1 specimen from “Banat” identified by Korge based on the illustrations in Coiffait (1963). No other material identified as was ever mentioned in the literature.

It is difficult to establish the identity of two female syntypes of because they belong to the complex of species (resembling ) where the study of male genitalia is critical for the species identification. However, among the additional material from the Vienna Museum of Natural History (see above), there are three male specimens, one of which was identified by Bernhauer as . Although neither of them are syntypes of , they were collected near the type locality of that species. Examination of this valuable authentic material shows that is conspecific with Reitter, 1909, the latter species earlier revised in Solodovnikov (2004). (Figs 9–11) is widely distributed in Southern Europe, Asia Minor, and Transcaucasia, while this new synonymy clarifies its distributionin the southern Central Europe.

To fix the identity of Bernhauer, 1927, one of the syntypes (with the Bernhauer’s label “type”) is designated as a lectotype. The syntypes of were revised in Solodovnikov (2004), of them one male is designated here as a lectotype. Both lectotype designations are done for the unambiguous fixation of the names placed in synonymy.

Quedius richteri Korge, 1966, syn. n.

: Holotype: Germany: female, ”Stolpe a. Oder Uckermark, 1986/ Quedius (Sauridus) richteri Korge ♀ - Holotypus”; paratype: 1 male, “Stolpe/ Mark leg. D. Richter / Glykolfallen August 1965/ Paratypus Quedius richteri Korge” (cKrg). Additional specimen: 1 ?female [apex of the abdomen missing],PageBreak same data as in paratype, marked as paratype [but not listed in the type series in the original description].

Remarks

The female holotype, the damaged male paratype (Figs 12, 13), and the unsexed specimen (without apex of abdomen, marked as “paratype” but not listed PageBreakin the original description) are the only specimens known as Korge, 1966. As stated in the original description of (Korge 1966), and confirmed by the study of the type material here, externally this species is identical with (Grav.). The only available male of differs from (Grav.) in the shape of the aedeagus (Figs 12, 13). The aedeagus of that single male ofPageBreak shares the same structural plan with the aedeagus of and, at the same time, it displays some abnormal asymmetry. These facts, combined with the somewhat deformed external morphology of the corresponding male paratype of , suggest that it is a teratological specimen of (Grav.). Therefore, the name Korge, 1966 is placed in synonymy with (Gravenhorst, 1806), a wide-spread European species that is rather common in Central Europe. Lack of any other collecting events of , described from the area of very strong entomological attention, is additional strong evidence for the mentioned teratology of and resulting synonymy.

Quedius merlini Drugmand & Bruge 1991, syn. n.

Remarks.

was described from three specimens (one male, two females) collected in Belgium (Tenneville, Fange Massa) in 1986 in a Lundgren trap (Drugmand and Bruge 1991). Unfortunately the type material of this species was not located at the Royal Institute of Natural Science at Brussels, but the original description and illustrations of leave no doubts that those specimens are misidentified Ksw. After the description, was never recorded again either in Belgium or anywhere else. For such an entomologically popular region as Central Europe, this is additional evidence that is not a valid species.
