Paratype: 1♀ (IZCAS-Ar41967), same data as holotype; 1♀ (IZCAS-Ar41968), Nepal, Mechi District, Taplejung, 27.35°N, 87.70°E, ca. 2452 m, 2.IV.2019, C. Shrestha leg.

Etymology.

The specific name is a noun in apposition taken from the type locality.

Diagnosis.

The male of Pimoa mechi sp. nov. resembles P. yadong Zhang & Li, 2020 (see Zhang et al. 2020: 99, fig. 14A-C) but can be distinguished by the large pimoid cymbial sclerite (Fig. 55D) (vs. smaller) and by the long cymbial denticulate process (Fig. 55D) (vs. short). The female of P. mechi sp. nov. resembles those of P. crispa (see Hormiga 1994a: 63, figs 239-247) and P. samyai (see Zhang et al. 2020: 97, fig. 13A-D) but can be distinguished from P. crispa by the broad dorsal plate (Fig. 25B) (vs. narrow) and from P. samyai by the spermathecae separated by a short distance (Fig. 25A) (vs. separated by ca. 1/2 width of a spermatheca) and also by the distally pointed dorsal plate (Fig. 25B) (vs. blunt).
