Etymology.

The species name is an adjective referring to the type locality.

Diagnosis.

Males of P. cuyapoensis sp. nov. resemble those of P. xichang sp. nov. but can be distinguished by the rounded embolus (vs. wavy embolus), 3 distinct bristles on the cymbial protrusion (vs. 2 distinct bristles on cymbial protrusion), length of palp ca 6 times the length of bulb (vs. extremely slender and long palp, ca 10 times the length of bulb (Fig. 9C, D View Figure 9 ), and coloration of male and female are pale brown (vs. coloration of male and female are darker brown); females can be distinguished by tubular spermathecae (vs. earlobe-shaped spermathecae).

Male (Holotype). Total length 1.60; carapace 0.60 long, 0.67 wide; abdomen 1.00 long, 0.78 wide. Carapace round and brown, with 3 longitudinal dark brown bands, median band half carapace length, median band almost as wide as the lateral bands (Fig. 6D View Figure 6 ).
