Type material.
Holotype: ♂ (IZCAS-Ar2016), China, Tibet, Nyingchi, Zayu County, Ridong Village, 28.52°N, 98.08°E, ca. 3572 m, 30.VII.2019, X. Zhang, Z. Bai and J. Liu leg. Paratypes: 1♂2♀ (IZCAS-Ar42017-Ar42019), same data as holotype.
Etymology.
The specific name is a noun in apposition taken from the type locality.
Diagnosis.
The male of Pimoa zayu sp. nov. resembles those of P. gandhii (see Hormiga 1994a: 73, figs 218-223) and P. nematoides (see Hormiga 1994a: 71, figs 285-289) but can be distinguished by the cymbial denticulate process with many cuspules (Figs 51B View Figure 51 , 58B View Figure 58 ) (vs. few cuspules), from P. gandhii by the longer, membranous pimoid embolic process (Fig. 58B View Figure 58 ) (vs. almost as long as embolus), and from P. nematoides by the broad cymbial denticulate process (Fig. 58B View Figure 58 ) (vs. narrow). The female of P. zayu sp. nov. also resembles P. gandhii (see Hormiga 1994a: 73, figs 224-231) but can be distinguished by the unseparated pair of nearly rectangular spermathecae (Fig. 52A View Figure 52 ) (vs. oval, separated by ca. 1/3 width of a spermatheca).
