Draposa
gen. nov.
Type
species:
Lycosa nicobarica Thorell
, 1891.
Etymology. The name is an anagram of the name
Pardosa
. The gender is feminine.
Diagnosis. Males of
Draposa
gen. nov.
differ from other lycosids by the presence of a subpaleal sclerite with two processes partly hidden by the palea in the terminal part of the bulbus, as well as by the tegular apophysis being transverse with wide basal part carrying variously shaped projections and narrow distal part carrying small subapical protrusion before evenly curved tip (e.g., Figs 13 & 16); females differ by the epigyneal cavity being only partly divided by a tongue-like septum (e.g., Figs 19 & 40).
Description. Lycosid spiders of small to medium size (carapace length approx. 2.00-4.55).
Carapace brownish with light brownish to yellowish median and lateral bands. Eye row I considerably shorter than eye row II. Eye row I slightly procurved, anterior median eyes slightly larger than anterior laterals (0AME/0ALE 1.15-1.25). Chelicerae with rows of three retromarginal and three promarginal teeth, distalmost tooth in latter row small and knob-like (Fig. 36). Labium slightly wider than long. Leg lengths
IV
>I>II>III or IV>I>III>II. Mt IV as long as or shorter than Pt + Ti IV (measured dorsally). Ti I with three pairs of ventral spines (of which three are placed in an oblique line prolaterally). Male palp with subtegulum covered by wrinkled integument confluent with basal haematodocha (no lunar plate). Tegular apophysis prominent, transverse, without anteriorly directed branch as present in
Pardosa
sensu stricto
. [A transverse tegular apophysis is also present in other
Pardosa
sensu lato
groups, like the speciose Old World
Pardosa
nebulosa-group
(Alderweireldt &
Jocque
1992, Yin et al. 1997). In the latter, it differs from that of
Draposa
by being shorter and without protrusions as well as by terminating in a sclerotised hook-like tip]. Wide basal half of tegular apophysis with variously shaped projections, in several species tooth-like and more or less pointed. Narrow distal part with small subapical protrusion (e. g., Figs 13 & 16) and distally tapering into narrow evenly curved tip. [A conductor as recognized in
Pardosa
(Kronestedt 1975; Dondale 1986; Dondale & Redner 1990) is not present in
Draposa
.] Palea with retrolateral paleal apophysis (Fig.12; topological term not implying homology with somewhat similar condition, e.g., in
Acantholycosa
Dahl, 1908 cf. Marusik et al. 2003). Palea more or less covering subpaleal sclerite protruding into two prominent processes (Fig. 12), presumably unique feature for
Draposa
. Epigyne with deep central cavity (e. g., Figs 19 & 40). Lateral elevations partly protruding over central cavity (in ventral view). Tongue-like septum protruding from in front into epigyneal cavity. Bottom of cavity extending laterad, covering all or most of spermathecae (in dorsal view: Figs 20, 22, 41, 43).
Species of
Draposa
gen. nov.
have a 'pardosoid' appearance (i. e. being thin-legged, agile and diurnal, similar to species of
Pardosa
sensu stricto
).
Remarks. Published illustrations indicate that there are species other than those treated in detail in this paper, which may qualify for transfer to
Draposa
: the males of both
Pardosa aciculifera
Chen
, Song & Li, 2001 (figs 4-7) from Hainan (China), and
P. burasantiensis Tikader & Malhotra
, 1976 (fig. 12; Tikader & Malhotra 1980, fig. 186) from West Bengal (India) apparently possess a subpaleal sclerite with apophyses mostly hidden by the palea in the terminal part of the bulbus as well as the shape of the tegular apophysis that is characteristic for species now placed in
Draposa
gen. nov.
[The species referred to as
P. burasantiensis
from Yunnan and Hunan (China) in Yin et al. (1997: 239, fig.
112 ♂
♀) and Song et al. (1999: fig. 194C ♀), however, appears to belong to some species in the
Pardosa
nebulosa-group
.]
Pardosa amkhasensis Tikader & Malhotra
, 1976 (fig. 2; Tikader & Malhotra 1980, fig. 177) and
P. minutus Tikader & Malhotra
, 1976 (fig. 4; Tikader & Malhotra 1980, fig. 147), both known only from females, should also be studied from the aspect of belonging in
Draposa
gen. nov.
Distribution. Indomalayan region: Pakistan, India, Sri Lanka, Bangladesh, Myanmar, China, Malaysia, Indonesia.
