Zhang & Zhu, 2009
(see
Zhang & Zhu 2009
: 75, fig. 42 and
Yao & Li 2012
: 31, figs 149–150) in with male chelicerae (
Fig. 24
D), uncus (
Fig. 24
C) and epigynum (
Fig. 24
A) but can be distinguished by the very thick subdistal sclerite on the procursus (arrow in
Fig. 23
C), by the presence of an angular branch medially on the appendix (
Fig. 24
C), by the elliptic pore plates and by the absence of lateral outgrowths on the vulva (
Fig. 24
B).
Description. Male (
holotype
):
Total length 4.42 (4.55 with clypeus), carapace 0.81 long, 0.98 wide, opisthosoma 3.44 long, 0.65 wide. Legs missing. Distance PME-PME 0.29; diameter PME 0.14; distance PME- ALE 0.10; distance AME-AME 0.11; diameter AME 0.08. Sternum wider than long (1.21/0.94). Habitus as in
Figs 24
E–F. Carapace yellowish, with dark brown radiating marks extending to ocular area, ocular area brown; sternum brown. Opisthosoma yellowish, with spots dorsally and laterally. Ocular area elevated, without eye-stalks (as in
P. gonggarensis
sp. nov.
, cf.
Fig. 27
C). Thoracic furrow absent. Chelicerae as in
Fig. 24
D, with a pair of proximomedial apophyses, a pair of black distal apophyses, and a pair of frontal apophyses. Pedipalps as in
Figs 23
A–B; trochanter with a ventral apophysis; femur with two distinct ventral ridge; tibia with a projection prolaterally; procursus simple proximally but complex distally, with a very thick subdistal sclerite (arrow in
Fig. 23
C); uncus with a scaly edge; appendix hooked, with an angular branch medially; embolus weakly sclerotized, with some nearly transparent projections distally. Legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae.
Female:
Similar to male, habitus as in
Figs 24
