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 View Figure 49 , 58A View Figure 58 ) but can be distinguished by the pimoid embolic process that is wider distally than the rest of the process (Fig. 54A View Figure 54 ) (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 View Figure 1 , 54A View Figure 54 ) (vs. without a spine), and distinguished from P. yele sp. nov. by the embolus beginning at the 5:00 o’clock position (Fig. 54A View Figure 54 ) (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 View Figure 50 ) but can be distinguished from P. lata by having the dorsal plate shorter than the ventral plate (Fig. 2B View Figure 2 ) (vs. dorsal plate longer than the ventral plate) and by the unseparated spermathecae (Fig. 2A-D View Figure 2 ) (vs. spermathecae separated), and can be distinguished from P. yele sp. nov. by the dorsal plate being blunt distally (Fig. 2A-D View Figure 2 ) (vs. pointed distally).
