Type material.
Holotype
:
♂ (IZCAS-Ar41997), China, Tibet, Lhoka, along provincial highway 306 from Gyaca County to Sangri County,
29.05°N
,
92.39°E
, ca. 4329 m, 27.VIII.2018, X. Zhang, Z. Bai and J. Liu leg.
Paratypes
: 1♂2♀ (IZCAS-Ar41998-Ar42000), same data as holotype.
Etymology.
The specific name is a noun in apposition taken from the type locality.
Diagnosis.
The male of
Pimoa sangri
sp. nov. resembles those of
P. gandhii
(see
Hormiga 1994a
: 60, figs 218-223) and
P. nyingchi
(see
Zhang et al. 2020
: 91, fig. 8A-C) but can be distinguished from
P. gandhii
by the V-shaped pimoid cymbial sclerite (Fig.
57B
) (vs. L-shaped), by having the pimoid embolic process shorter than the embolus (Figs
41A
,
57B
) (vs. longer), and distinguished from
P. nyingchi
by the embolus beginning at the 4:30
o'clock
position (Fig.
57B
) (vs. 3:00), and the narrow cymbial denticulate process (Fig.
57B
) (vs. broad). The female of
P. sangri
sp. nov. also resembles
P. gandhii
(see
Hormiga 1994a
: 60, figs 224-231) but can be distinguished by the wide proximal fertilization ducts (Fig.
42A
) (vs. narrow) and by the rectangular spermathecae, divided into two parts (Fig.
42A
) (vs. oval).
