Type material.
Holotype female: CHINA:
Yunnan Province
: Lijiang City, Yongsheng County, Lingyuan Temple,
26.70°N
,
100.78°E
, 2305 m, 25 August 2013, Yang Zhong & Xiaowei Cao leg. (CBEE, LJ01667);
Paratypes
: 2 females, with same data as holotype. (CBEE, LJ01668-LJ01669).
Etymology.
The specific name is derived from the Latin adjective
physematosus
, -
a
, -
um
, meaning swollen, referring to the shape of SIDS in dorsal view (
Fig. 5C
); adjective.

Diagnosis
.
Pseudopoda physematosa
sp. nov. differs from other species of the
P. signata
group, except
P. bibulba
, by the SIDS with well developed twisted loops, in ventral view. It can be distinguished from
P. bibulba
by the following characters: anterior margins of lateral lobes longer than half the width of epigynal field in
P. physematosa
, but shorter in
P. bibulba
; SIDS folded, with swollen tip in
P. physematosa
, but not in
P. bibulba
(
Fig. 5A
).

Measurement of palps and legs: Pp 4.5 (1.3, 0.5, 1.0, -, 1.7); I 12.8 (3.8, 1.9, 2.8, 3.1, 1.2); II 13.0 (4.0, 1.3, 3.0, 3.2, 1.5); III 11.1 (3.1, 1.6, 2.7, 2.6, 1.1); IV 11.6 (3.1, 1.7, 3.0, 2.7, 1.1). Promargin of chelicerae with three teeth, retromargin with four teeth, cheliceral furrow with ca. 32 denticles. Epigynal field almost as wide as long, with anterior bands included in the field. Epigyne with lateral lobes touching each other posteriorly. The anterior margins of lateral lobes forming a
"V"
. FW covering most of SIDS, the latter folded in the middle part (
