Diagnosis

Habitus: Fig. 1 c, d. Male genitalia: Fig. 2 c, d. Maxillary palpus: Fig. 3 c, d. Pronotum: Fig. 4 c.

Body length = 12.8-14.6 mm. Dorsal surface black. Terminal maxillary palpimere cylindrical, as long as penultimate one. Pronotum black, widely cordate (pronotum width / pronotum length = 1.37-1.44), widest a little behind anterior third; pronotum completely smooth between basal foveae; lateral margins strongly sinuate in front of posterior angles; posterior angles rectangular with sharp apices.

This species can be well distinguished from other Chinese species by its characteristic pronotum that is strongly cordate with evident sinuation in front of posterior angles, which are sharp.

Remarks

This species is somewhat similar to P. aethiops distributed in Myanmar. Based on the descriptions in literature ( Roux et al. 2016), these two species are mainly different in the shape of pronotum: lateral margins evidently sinuate before posterior angles in P. luangphabangensis , but hardly sinuate in P. aethiops ; apex of posterior angles sharp in P. luangphabangensis , but nearly rounded in P. aethiops .
