Further notes on New Zealand Enantiobuninae (Opiliones, Neopilionidae), with the description of a new genus and two new species.

Mangatangi parvum gen. n. and sp. and Forsteropsalis pureroa sp. n. are described from the North Island of New Zealand. Pantopsalis listeri (White 1849) and Pantopsalis cheliferoides (Colenso 1882) are redescribed and no longer regarded as nomina dubia; Pantopsalis luna (Forster 1944) is identified as a junior synonym of Pantopsalis listeri. A key to Pantopsalis species is provided.

Introduction

The Enantiobuninae (sensu Taylor 2011, including the Monoscutidae of Crawford 1992) are the dominant group of long-legged harvestmen (Opiliones: Palpatores) found in New Zealand, with over twenty species currently recognised from there (Taylor 2004, 2008, 2011). New Zealand Enantiobuninae can be divided into two separate groups, probably representing distinct clades (Taylor 2011). The first group, previously PageBreakrecognised as the Monoscutinae (Crawford 1992), is only known from three heavily sclerotised species (Forster 1948, Taylor 2008). The greater majority of species belong to the second group, containing taxa previously assigned to the Megalopsalidinae (Crawford 1992). The New Zealand representatives of this group have long been assigned to two genera, and , until Taylor (2011) demonstrated that the New Zealand ‘Megalopsalis’ species were not closely related to the Australian type species of that genus and transferred the bulk of them to a New Zealand endemic genus (leaving a single anomalous species, ‘Megalopsalis’ triascuta Forster 1944, whose affinities remain to be demonstrated).

Both genera are represented in museum collections by material from throughout both of the main islands of New Zealand (personal observations). However, accidents of history have resulted in the fauna of the South Island being more extensively investigated than that of the North Island, with the greater number of described species coming from the former. Only one species of and four species of have been described to date from the North Island. In examining North Island material held in the collection of Te Papa Tongarewa, Wellington (MONZ), a further species of was recognised, as well as specimens of the previously inadequately described . Examination of these specimens, as well as of specimens attributed to (White 1849) held in the Muséum national d’Histoire naturelle, Paris (MNHP), allowed these two species to be properly characterised and no longer dismissed as nomina dubia.

A third novel species from the North Island is of particular interest as it does not accord with either or , and may represent an outgroup to both. It is here described as representing a new genus.

Methods

Specimens were sourced from the collections of Te Papa Tongarewa, Wellington, New Zealand (MONZ) and the Muséum national d’Histoire naturelle, Paris, France (MNHP). Photographs and measurements were taken using a Nikon SMZ1500 stereo microscope and the NIS-Elements D 4.00.03 programme, and a Leica DM2500 compound microscope. Coloration is described as in alcohol. Measurements are given in millimetres.

Diagnosis.

can be distinguished from all other New Zealand Enantiobuninae by the presence of a well developed tooth comb on the pedipalpal tarsal claw. It can be distinguished from , and by its relatively long legs and unsclerotised dorsum. It differs from ‘Megalopsalis’ triascuta, all and most species in the absence of either a mediodistal apophysis or hypersetose region on the pedipalpal patella, from species by its relatively bowed cheliceral fingers, and from species by the absence of denticles on the medial side of the pedipalp coxa. can also be distinguished from all other New Zealand species, so far as is known, by its genital morphology: all other New Zealand species investigated to date have a relatively long glans that is either narrow in lateral view (most species) or possesses a distinct dorsal keel (). The deep and short glans of is also distinct from that of Enantiobuninae elsewhere: species have a very elongate and relatively flat glans, and and species have a short but also distally flattened glans. The only other Enantiobuninae in Australasia to possess comparatively deep glans are and ; differs from in possessing relatively long legs and retaining an anterior grill of spines over the spiracle, and from in lacking a large dorsolateral flange at the junction between shaft and glans. The glans of has never been illustrated in lateral view, but is clearly distinguished from that genus by possessing paired bristle groups at the junction between shaft and glans rather than single bristles.

Description.

Male (Figs 1a–b, d–e, g–i, l): Total body length 2.06–2.74 (larger value in all measurements represents holotype), prosoma length 0.97–1.19, prosoma width 1.76–2.01.

Claw with ventral tooth-comb.

Legs: Leg I femur 2.99–3.80, patella 0.71–0.91, tibia 2.93–3.87; leg II not preserved; leg III 2.56–3.38, patella 0.77–0.93, tibia 2.70–3.45; leg IV femur 4.05–5.01, patella and tibia not preserved.

Pedipalp (Fig. 1f) with microtrichia over entire patella, tibia and tarsus except glabrous dorsal line on patella and tibia. Ovipositor (Figs 1j–k) with single pair of seminal receptacles.

Phylogeny.

is probably related to the clade formed by and , with which it shares the presence of sharp papillae on the glans, and of setae close to the major tooth of the mobile finger of the chelicera (this last feature is also present in ). The retention in of a plesiomorphic tooth-comb on the pedipalpal tarsal claw, together with ’s distinctly short glans, could suggest a sister relationship between and the PageBreak + clade, but this should perhaps be treated with caution. and each retain reduced teeth arrays (a single tooth in the latter species) on the tarsal claw, and that of has a ventral rugose area that may correspond to the remains of the tooth-row. The loss of the tooth-row in and has therefore happened at least partially in parallel. As regards the short glans of compared to the long glans of and , our understanding of enantiobunine phylogeny is not yet robustly resolved (Taylor 2011) and it is questionable which state is plesiomorphic for the clade.

Named for the type locality.

The genus was established and revised by Taylor (2011). In the key to provided therein, can easily be taken as far as couplet 6: it differs from in lacking the latter’s flattened and ventrally white opisthosoma, from and in not having the chelicerae greatly inflated and the cheliceral fingers widely bowed, and from and in not having the posterior part of the propeltidium and the mesopeltidium heavily denticulate. The only species with which is likely to be confused are , , and . can be distinguished from by the presence of denticles in the anterior propeltidial area, whereas has the prosomal dorsum unarmed but for the anterior corners. From , and , can be distinguished by the absence of a distinct pedipalpal patellar apophysis. It can also be distinguished from by the absence in the latter of denticles on the femora. and are larger species (both have the prosoma more than 2 mm in length) with more developed denticulation at the anterior corners of the prosoma, and without any medial stripe on the opisthosoma. The latter two species also differ from in genital morphology: both have the glans in ventral view narrowing anterior to the lateral bristle groups (Taylor 2011, Figs 97, 118) while that of is more constant in width.

Male: Total body length 3.73, prosoma length 1.77, prosoma width 2.83. Dorsal prosomal plate honey-brown with large white patches covering much of median propeltidium on either side of ocularium and becoming diffuse behind ocularium, postocularial area yellow-grey; anterior propeltidium with sharp denticles, remainder of dorsum unarmed but with scattered black setae; ocularium PageBreakwhite. Mesopeltidium forming raised ridge, medially pale yellow-grey, darkening to honey-brown laterally. Ozopores on raised lateral lobes, anterior ozopore lobe with distinct white patch, remainder of lateral shelves honey-brown with smaller white patches on posterior ozopore lobe and near posterior end of shelf. Metapeltidium and dorsum of opisthosoma light purple with median white stripe and transverse rows of white spots across segments. Mouthparts white; coxae mottled honey-brown proximally, darker brown distally; genital operculum honey-brown; venter of opisthosoma light purple.

Chelicerae: Segment I 7.06, segment II 8.94. Segment I darker yellow-brown with white patches at distal end; segment II orange-brown; both segments evenly denticuPageBreaklate; segment II not inflated. Cheliceral fingers (Fig. 2c) long, only slightly bowed, movable finger with numerous setae close to median tooth.

Pedipalps: Femur 2.00, patella 0.98, tibia 1.21, tarsus 2.75. Coxa with numerous sturdy denticles on prolateral margin. Pedipalps long, slender, femur with dorsal and ventral rows of denticles; femur proximally honey-brown except cream-coloured heel; distal end of femur, patella and tibia white mottled with cream; tarsus cream-coloured. Patella and tibia (Fig. 2d) straight, patella with concentration of strong setae at prolateral distal end but without distinct apophysis. Microtrichia on distal two-thirds of tarsus. Tarsal claw ventrally rugose.

Legs: Leg I femur 7.03, patella 1.48, tibia 6.04; leg II femur 11.70, patella 1.74, tibia 11.64; leg III femur 7.00, patella 1.51, tibia 5.44; leg IV femur 8.32, patella 1.38, tibia 7.83. Femora with relatively few small denticles dorsally; other segments unarmed. Trochanters honey-brown with white distal retrolateral spot on each trochanter. Femora proximally dull medium yellow, distal ends of femora to tibiae honey-brown mottled with white spots; tibiae lighter orange-brown banded with dull yellow. Tibia I with two pseudosegments; tibia II with ten pseudosegments; tibia IV with three pseudosegments.

Penis (Figs 2e–f): Glans relatively long, sides parabolic in ventral view; triangular in lateral view. Bristle groups of medium length. Tendon long.

Comments.

Another feature of that may deserve further investigation is the unusually high number of pseudosegments in the leg tibiae. Not only does the holotype have a higher number of pseudosegments in tibia II than recorded for any other species, even the particularly large species and , it represents the first recorded instance in this genus of pseudosegmentation in tibia I. At our present level of knowledge, this cannot be considered a reliable distinguishing character for the species as tibial pseudosegment number has been found in other species to vary between individuals. However, pseudosegment number has been suggested to distinguish and in which, so far as is known, males of each species have varying but non-overlapping ranges of pseudosegment number for tibia II (Taylor 2011). This may reflect differences in leg proportions between the two species: despite having a generally larger body size than (average prosomal length 3.1 mm in two specimens of vs 2.5 mm in four specimens of ), specimens may have relatively longer legs (average length of tibia II 9.8 mm in vs 11.8 mm in ) (unpublished personal observations). Like examined specimens of , the holotype of has relatively long legs compared to body size. However, the significance of these observations remains open to question. Previous morphometric studies of other Opiliones have found leg measurements to be useful in distinguishing taxa among Goniosomatinae (Laniatores; Gnaspini 1999) but not (McGhee 1977). A detailed morphometric study to establish the reliability and/or significance of such measurements in distinguishing taxa will require a much larger sample of specimens than currently available for most species.

As described by Simon (1879), with the following additions: Dorsum of opisthosoma with pale silvery, narrow, transverse stripes on posterior margins of segments (Fig. 3b). Segment II of chelicera inflated in neotype, slender in remaining specimens. Glans of penis without dorsal keel (Taylor 2004: Fig. 9).

The original type specimen(s) of are lost; they have not been located in the collection of the Museum of Natural History, London (J. Beccaloni, pers. com.) or of the Muséum national d’Histoire naturelle, Paris (M. Judson, pers. com.) It was therefore treated as a nomen dubium by Taylor (2004). A redescription of was provided by Simon (1879), who made it the type species of his new genus .

Since the publication of Taylor (2004), I have had the opportunity to examine two of the specimens used by Simon (1879) in his redescription of this species. Their state of preservation is not ideal (they appear to have been subject to desiccation at some point in the past) and the genitalia have become distorted. Nevertheless, I was able to confirm the absence of a dorsal keel on the glans, demonstrating that could not be conspecific with , or among other South Island species. External characters (described by Simon 1879), such as the unarmed ocularium with denticles restricted to the anterior propeltidium on the dorsal prosomal plate, are also consistent with male specimens referred to (Forster 1944) by Taylor (2004) (pers. obs.), and it is my judgement that that species is a junior synonym of sensu Simon (1879). The opisthosoma has collapsed in both MNHP specimens, so Simon’s (1879) failure to note the transverse striping present in this species may be an artefact of preservation and does not oppose the synonymy.

White’s (1849) original description of does not provide a more detailed type locality than ‘New Zealand’, but Judson (1997) suggested the Bay of Islands, North Island, as the likely type locality for White 1849 (now ), described in the same paper. If this was also the case for , then Simon’s (1879) specimens would be unlikely to represent the same species as White’s PageBreakoriginal type(s). Simon (1879) did not explicitly indicate how he identified his specimens as ; as no other New Zealand enantiobunine had yet been described, Simon was probably simply unaware that more than one phalangioid species with enlarged chelicerae existed there. Nevertheless, one of the MNHP specimens (Fig. 3a) is here designated as neotype of . White’s original description was exceedingly rudimentary, giving basic characters of the chelicerae only, and inadequate for determining which of the genera , or was being examined. Simon’s more detailed redescription was at least implicitly used as the basis for identification of by all subsequent authors (Pocock 1903a, b, Hogg 1910, 1920, Roewer 1923, Taylor 2004). Nomenclatural stability is best served by fixing ’s identity as the species examined by Simon.

Description:

Male: Total body length 3.55–4.03 (former measurement refers to 2004 specimen), prosoma length 1.62–2.06, prosoma width 2.55–3.70. Dorsal prosomal plate medium brown, with some yellowish patches laterally; anterior propeltidium and ocularium heavily denticulate, remainder of prosoma unarmed. Dorsum of opisthosoma dark purplish brown with few white spots medially in one specimen, longitudinal purple medial stripe in other; larger white spots in present in central part of opisthosomal dorsum, comparable to lateral ‘arms’ of median stripe in females of other species. Coxae medium brown mottled with honey brown; venter of opisthosoma medium purplish brown mottled with lighter purple.

PageBreakChelicerae: Segment I 4.73–6.23, segment II 6.36–8.47. Segment I medium brown with cream patches at distal end; segment II orange-brown; both segments heavily denticulate. Segment II inflated in larger specimen, slender in smaller. Cheliceral fingers (Fig. 4c) short, mobile finger crescent-shaped.

Pedipalps: Femur 1.81–2.32, patella 0.97–1.15, tibia 1.01–1.18, tarsus 2.10–3.02. Femur light purple at base, remainder of pedipalp shining white. Patella and tibia (Fig. 4d) prolaterally hypersetose, patella bulging prodistally but without distinct apophysis. Microtrichia on distalmost end of tarsus only. Tarsal claw with single ventral tooth.

Legs: Leg I femur 7.91–8.56, patella 1.36–1.58, tibia 6.03–6.14; leg II femur 13.25–13.69, patella 1.82–1.80, tibia 11.18–11.47; leg III femur 6.91–7.38, patella 1.32–1.45, tibia 5.22–5.48; leg IV femur 9.88–10.81, patella 1.57–1.59, tibia7.53–7.38. Femora evenly but irregularly denticulate, except distal third of femur II unarmed; remaining segments unarmed. Legs medium brown mottled with yellowish, tibiae and tarsi tinged with purple, tibiae spotted with white; tarsi with white band at base of telotarsi. Tibia II with five pseudosegments; tibia IV undivided in larger specimen, with two pseudosegments in smaller.

Penis (Fig. 4e–f): Glans medium length, sides parabolic in ventral view; subtriangular in lateral view but not markedly flattened, slight dorsomedial bulge but keel essentially absent. Bristle groups short. Tendon long.

There is some variation in coloration between the two specimens available, most notably the presence of a medial stripe on the opisthosoma of one but not the other, with the former specimen also being overall lighter in coloration than the latter. It is possible that this difference may reflect differences in maturity between the two specimens, similar to what has been recorded for other Opiliones species (Shultz 2008). Such long-term darkening after moulting may also explain the anomalously pale specimens of recorded by Taylor (2004).

Long regarded as something of a mystery after its initial description by Colenso (1882), was referred to only in footnotes by Forster (1944) and Marples (1944), and treated as a nomen dubium by Taylor (2004) due to the poor condition of the type specimen. This was unfortunate as, with the recognition of ‘Pantopsalis’ wattsi Hogg 1920 as a species of (Taylor 2011), was the only species of described from the North Island. The two specimens examined here, though collected some distance from the type locality, are consistent with Colenso’s (1882) original description and discernable features of the type specimen (Taylor 2004) and, in the absence of evidence to the contrary, can be identified as . This species can, therefore, be confirmed as distinct from other identifiable species of .

The absence of a distinct dorsal keel on the glans of the penis clearly distinguishes from all other species except and possibly (for which the genital morphology remains unknown). has a very distinct colour pattern, with transverse light coloured stripes on the dorsum of the opisthosoma (Taylor 2004). lacks a ventral tooth on the pedipalpal tarsal claw, has the ocularium unarmed with denticulation on the prosoma restricted PageBreakto the anterior propeltidial region, and has narrow transverse stripes on the dorsum of the opisthosoma (personal observations, male specimens from Waiho Gorge, South Island, cited by Taylor 2004).

The presence of dimorphic males as described for other species by Taylor (2004) in both and is of note. Previous species in which this phenomenon has been observed (, , and ) all belong to the well-marked species group whose members possess a strong dorsal keel on the glans (Taylor 2004) and it was previously unknown whether such male dimorphism occurred outside this species group. Its presence in the two species treated herein indicates that it does, and it may indeed be a synapomorphy for as a whole.

Key to males of

The last author to provide a key to species of was Roewer (1923). Since then, a number of species have been described, several of the species referred to by Roewer have been synonymised, and characters of the chelicerae referred to by Roewer have been shown to vary within species (Taylor 2004). Therefore, the opportunity is taken to provide an updated key to males. Hogg 1920 is omitted from the following key, as it is currently based only on a female specimen and not identifiable (Taylor 2004). and are not currently distinguishable, but Taylor (2004) refrained from synonymising them on the basis of their widely disjunct distributions. Their relationship requires further investigation.
