Differential diagnosis
The male resembles that of P. lamottei sp. nov. in having a similar sinusoid shape of the anterior lobe of the bulb, but may be recognized by the presence of a short spike at the base of the lobe on its prolateral side (compare Fig. 13C with Fig. 1C). The female is similar to that of P. perezi comb. nov. in having the epigyne with a V-shaped anterior depression, but may be distinguished by the atrial area narrower than the area occupied by spermathecae (Fig. 15A), quite the opposite to that of P. perezi comb. nov. (Fig. 8A–C).
