Type material.
Holotype
:
♂ (IZCAS-Ar41949), China, Tibet, Shigatse, Gyirong County, Gyirong Town, near Lhanggyi Tso Holy Lake,
28.41°N
,
85.40°E
, ca. 3909 m, 7.VII.2019, X. Zhang, Z. Bai and J. Liu leg.
Paratypes
: 1♂2♀ (IZCAS-Ar41950-Ar41952), same data as holotype.
Etymology.
The specific name is a noun in apposition taken from the type locality.
Diagnosis.
The male of
Pimoa gyirong
sp. nov. resembles those of
P. crispa
(see
Hormiga 1994a
: 63, figs 233-238;
Hormiga 1994b
: fig. 1A, B) and
P. rongxar
Zhang & Li, 2020 (see
Zhang et al. 2020
: 94, fig. 10A-C) but can be distinguished from
P. crispa
by the distally narrower cymbial denticulate process (Fig.
55A
) (vs. wider) and distinguished from
P. rongxar
by the broad cymbial denticulate process, with many cuspules distally (Figs
15B
,
55A
) (vs. distally narrow, with few cuspules) and the shorter pimoid cymbial sclerite (Fig.
55A
) (vs. large and wide subdistally). The female of
P. gyirong
sp. nov. resembles those of
P. nyingchi
(see
Zhang et al. 2020
: 91, fig. 9A-D) and
P. reniformis
(see
Xu and Li 2007
: 493, figs 42-47) but can be distinguished from
P. nyingchi
by the distally blunt dorsal plate (Fig.
16B
) (vs. pointed) and distinguished from
P. reniformis
by the spermathecae separated by ca. 1/4 the width of a spermatheca (Fig.
16A
) (vs. unseparated).
