Pimoa shoja Zhang & Li , sp. nov. ( Figs 28A–C , 29A–G )

Diagnosis. The male of Pimoa shoja Zhang & Li , sp. nov. resembles P. mainling (see Zhang et al., 2020: 89, fig. 6) and P. samyai Zhang & Li, 2020 (see Zhang et al., 2020: 97, fig. 12) but can be distinguished from P. mainling by the distally pointed PEP (vs. slightly wider distally in P. mainling ), and from P.samyai by the U-shaped PCS (vs. L-shaped in P.samyai ), and by the broad CDP, with many cuspules (vs. CDP short and distally narrow, with few cuspules in P. samyai ). The female of P. shoja Zhang & Li , sp. nov. resembles P.crispa (see Hormiga, 1994: 63, figs 239–247) and P.samyai (see Zhang et al., 2020: 97, fig. 13) but can be distinguished from the nearly round DP of the epigynum (vs. DP narrow in P.crispa and nearly tongue shaped in P.samyai ), from P.crispa by the nearly round S (vs. kidney shaped in P.crispa ), and by the S separated by a short distance (vs. separated by ca. 1/2 width of a spermatheca in P. samyai ).
