Diagnosis (male).
The males of
P. physematosa
share characters of the
P. signata
-group (
Zhang
et al.
2019
): short outgrowth on tegulum, embolus arising point in 7-9 o´clock position, and similar shape of the short vRTA. However, the embolus in
P. physematosa
is thinner and dRTA is shorter than those in other members of the
P. signata
-group. The males of
P. physematosa
also resemble those of
P. shuqiangi
Jäger and Vedel, 2007
(see
Jäger & Vedel 2007: 21
, figs 73–78) by: the shape of short RTA in retrolateral view; apical embolus filiform, and running three quarter of an oval. It can be distinguished from the latter by the following characters: 1. Tip of dRTA sharp (
Figs 8B
,
9B
; blunt in
P. shuqiangi
); 2. RTA arising in an acute angle from tibia (
Figs 8B
,
9B
; almost right angle in the latter species); 3. Prolateral tegulum distally with a blunt hump (
Figs 8A–B
,
9A–B
; absent in the latter species).

Cymbium with distinct retrolateral bulge; RTA arising basally from tibia, dRTA short, horn shaped in ventral view, vRTA broad, shovel-shaped; tegulum with hump, prolateral tegular outgrowth blunt, near the base of the conductor; spermophor and running submarginally in tegulum, slightly S-shaped prolaterally; embolus long, arising from 9 o’clock position on tegulum, basal half of embolus slightly broad; conductor arising from tegulum at 11 o’clock position, slender, bent distally and directed prolaterally.

Coloration in ethanol: Carapace yellowish, with dark spots and two lateral bands, margin with thin dash lines and gray black patterns. Cervical groove and radial furrow obvious. Longitudinal fovea dark brown. Each eye surrounded with circular black patch. Labium, gnathocoxae and sternum yellowish. Margin of sternum with some spots. Legs yellowish with spine patches and many spots. Dorsal opisthosoma yellowish with a wide black median belt, anterior half with black lateral patches; venter yellowish, with black patches (

Notes.
Among the specimens collected in
Yunnan
, males and females were captured together, and both sexes had the same color pattern of carapaces. This sample and the type material of
P. physematosa
were collected from similar places. According to the photos of
holotype
in
Zhang
et al
. (2019)
, the females were identified as
P. physematosa
(
Figs 8D–E
,
9D–E
). The males can reasonably be expected to be conspecific with
P. physematosa
.
