Diagnosis. Males can be distinguished from those of all other species by slender embolus very curved distally, 5 or more times tegulum length in retrolateral view ( Fig. 217 View FIGURES 217–224 ). Females resemble those of P. cambridgei , P. irminia and P. pulcher by the elongated, non triangular spermathecae ( Fig. 224 View FIGURES 217–224 ). They differ by having the spermathecae apex curved toward center, and central area with 3–4 oval lobes weakly sclerotized ( Fig. 224 View FIGURES 217–224 ). Additionally, males and females have the stridulatory organ with curved line of thick setae ( Figs 225, 227 View FIGURES 225–228 ).
