Diagnosis

This species closely resembles P. nipponicus in the shape of median apophysis of male and epigynum of female with a pair of eye­like anterior margins, but can be distinguished from the latter by subtegulum of male pedipalpus with a hump near middle, embolus beakshaped and a median fork lacking ( Fig. 12 ), females with spermathecae oval each side with a very small heads ( Figs 9–10 ).
