Type material.
Holotype
:
♂ (IZCAS-Ar41921), China, Sichuan, Jinchuan County, Anning Township, Dujiaogou Valley, Mt. Gada,
31.26°N
,
101.97°E
, ca. 3048 m, 24.XI.2019, Z. Chen leg.
Paratypes
: 1♂2♀ (IZCAS-Ar41922-Ar41924), same data as holotype.
Etymology.
The specific name is a noun in apposition taken from the type locality.
Diagnosis.
The male of
Pimoa anning
sp. nov. resembles those of
P. lata
Xu & Li, 2009 (see
Zhang and Li 2019
: 6, fig. 3A-C) and
P. yele
sp. nov. (Figs
49A, B
,
58A
) but can be distinguished by the pimoid embolic process that is wider distally than the rest of the process (Fig.
54A
) (vs. pimoid embolic process with two jagged tips in
P. lata
, and a broad and robust embolic process, with a distally bifurcate, scaled apex in
P. yele
sp. nov.). Additionally,
P. anning
sp. nov. can be distinguished from
P. lata
by the embolus, which has a short, slender spine proximally (Figs
1A
,
54A
) (vs. without a spine), and distinguished from
P. yele
sp. nov. by the embolus beginning at the 5:00
o'clock
position (Fig.
54A
) (vs. 8:00). The female of
P. anning
sp. nov. also resembles those of
P. lata
(see
Xu and Li 2009
: 57, figs 1-8;
Zhang and Li 2019
: 6, fig. 4A, B) and
P. yele
sp. nov. (Fig.
50A-D
) but can be distinguished from
P. lata
by having the dorsal plate shorter than the ventral plate (Fig.
2B
) (vs. dorsal plate longer than the ventral plate) and by the unseparated spermathecae (Fig.
2A-D
) (vs. spermathecae separated), and can be distinguished from
P. yele
sp. nov. by the dorsal plate being blunt distally (Fig.
2A-D
) (vs. pointed distally).
