Etymology.
The specific name is a Latin adjective, meaning “broad” and referring to the broad fertilization ducts.
Diagnosis
. The females of this new species are similar to that of
P. reniformis
Xu & Li,
2007
in the position of the copulatory openings and the shapes of posterior copulatory ducts, but it can be distinguished by the distal ventral plate of epigynum that is modified into a lip-shaped apophysis, the pear-shaped spermathecae and the broad fertilization ducts.
Description.
Female. Total length 6.0–7.2.
Holotype
total length 6.1, cephalothorax 2.8 long, 2.4 wide, 1.5 high; abdomen 3.3 long, 2.0 wide, 1.8 high. AME diameter 0.16. ALE 1.23, PME 1.08, PLE 1.08 times AME diameter. AME separation 0.54 times their diameter, PME separation 0.71 times their diameter. AME- ALE separation 0.62 times AME diameter, PME-PLE separation 0.71 times PME diameter. Clypeus height 2.0 times AME diameter. Sternum 1.5 long, 1.5 wide, with distal end slightly broad. Labium wider than long. Chelicerae with 3 prolateral and 3 retrolateral teeth (
Fig. 3
). Cheliceral stridulatory striae present. Legs of
holotype
broken and the following description of legs are therefore based on a
paratype
with a total length of 7.0. Femora I–IV with 2 dorsal setae basally and femur I with 3 or 4 prolateral setae mesally. Patellae I–IV with 1 dorsal seta distally. Tibiae I–IV and metatarsi I-IV with numerous setae. Metatarsi I–IV with 1 trichobothrium dorsally, and Tm I 0.91. Leg lengths: I 26.5 (7.5+8.9+7.1+3.0), II 23.4 (6.85+8.0+6.2+2.6), III 16.6 (5.2+5.2+4.3+1.9), IV 20.31 (6.5+7.1+4.4+2.3). Leg formula: I, II, IV, III. Femur I 2.5 times length of cephalothorax. Abdomen brown. Dorsum with about 5 dark transverse patterns, anterior 2 of which separated and the posterior 3 fused (
Fig. 1
).
In lateral view, dorsal plate of epigynum partly visible (
Figs 2, 4
). From ventral view, vental plate modified into a lip-shaped apophysis distally and copulatory openings visible (
Fig. 5
). Spermathecae pearshaped. Copulatory ducts with one strong turn and with posterior part narrow. Fertilization ducts broad, oriented anteriorly (
Figs 7–8
).
Male. Unknown.
Distribution
. Only known from the
type
locality (Fig. 30).
Remarks:
This new species is the same species as “sp1” in
Wang et al. (2008)
.
