Paratypes
:
1♀
(IZCAS-Ar34097): same data as in
holotype
;
1♀
(IZCAS-Ar34098): same cave,
14–15. XII. 2012
, Z. Zhao and Z. Chen leg.;
3♀♀
(IZCAS-Ar34099-Ar34101): same cave,
5. XII. 2017
, Z. Chen leg.
Etymology.
The specific name refers to the
type
locality, Yumigan Cave; adjective.
Diagnosis.
The male can be distinguished from
T
.
qixianensis
sp. n.
by having a large lamella on conductor, small RTA, and a black spine next to RTA. From the similar
T
.
tortus
by the blunt tip of the patellar apophysis and a short cymbial furrow (1/2 the length of the cymbium
vs
. 2/3 the length of the cymbium). From the similar
T
.
liangensis
sp. n.
by the long patellar apophysis and a narrow conductor (
Fig. 12
B–C). Females can be distinguished from
T
.
nongchiensis
sp. n.
by the posterior margin of epigynal atrium belt-shaped
vs.
triangular (
Fig. 13
A–B).
