Diagnosis

Habitus: Fig. 1 a. Maxillary palpus: Fig. 3 a. Pronotum: Fig. 4 a.

Body length = 12.2-12.6 mm. Dorsal surface largely black. Terminal maxillary palpimere cylindrical, of similar width as distal end of penultimate one, distinctly longer than penultimate one. Pronotum faintly blue, transversal round (pronotum width / pronotum length = 1.40-1.42), widest a little behind anterior third; pronotum densely and coarsely punctate between basal foveae; lateral margins hardly sinuate in front of posterior angles; posterior angles rounded and obtuse.

This species can be well distinguished from other Chinese species by the terminal maxillary palpimere cylindrical, not wider, but much longer than the penultimate one.

Remarks

Xishuangbanna, the collection locality of the two specimens we examined, is quite far from South Vietnam, the type locality of P. adoxus . However, we are confident in determining them as P. adoxus because all characteristics are nearly identical to the description and images of this species ( Roux et al. 2016).

Distribution
