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

Diagnosis.

Pimoa gyaca sp. nov. resembles those of P. crispa (Fage, 1946) (see Hormiga 1994a: 63, figs 239-247) and P. mainling Zhang & Li, 2020 (see Zhang et al. 2020: 89, fig. 7A-D) but can be distinguished from P. crispa by the triangular ventral plate (Fig. 12A) (vs. distally blunt) and from P. mainling by the triangular epigyne (Fig. 12A) (vs. funnel shaped) and also by the spermathecae separated by the width of a spermatheca (Fig. 12A) (vs. ca. 1/3 width of a spermatheca).
