Diagnosis. This species is characterized by the following features: eyes 0.3 x longer than interocular distance in dorsal view; antennae extending beyond pronotum posterior lateral apices by antennomere VI or VII, surpassing elytral half by antennomere XI; antennomeres III distinctly longer than II; IV 1.3–1.4 x longer than III, 0.8–0.9 x longer than II–III combined; apical maxillary palpomere 1.9–2.4 x longer than wide, shorter than maximum length of eye; pronotum straightly and slightly narrowed ahead of hind angles; posterior edge of pronotum with sublateral incisions; hind angles of pronotum broad, weakly protruding posterolaterad; hypomeron with distinct mesial projection; anterior angle of hypomeron almost right angle; hind angle of hypomeron broadly triangular; scutellar shield almost as long as wide; mesosternal process between mesocoxae distinctly higher than mesocoxae, visible in lateral view; posterior edge of mesosternal process 0.2–0.25 x wider than total width of mesosternum; elytron 3.1–3.6 x longer than wide, 2.5–2.7 x longer than pronotum length; abdominal ventrite V semicircular, rounded apically; phallobase 0.9 x longer than wide; apex of parameres beyond preapical expansions large triangular; apex length 0.4–0.6 x width of parameres at expansions in ventral side; spiculum ventrale 5.6 x longer than length of sternite VIII; ovipositor longer than length of abdomen.
This species is similar to P. tsou in features of the eyes, the basal antennomeres, the apical maxillary palpomere, the hind angles of the pronotum, the anterior and hind angles of the hypomeron, the scutellar shield, the mesosternal process between mesocoxae, the elytron, and the abdominal ventrite V. It is distinguished by antenna length, the shapes of the pronotum and apex of parameres, and the degree of development of the mesial projection of the hypomeron (see diagnosis of P. tsou ).
