Diagnosis

Habitus: Fig. 1 b. Male genitalia: Fig. 2 a, b. Maxillary palpus: Fig. 3 b. Pronotum: Fig. 4 b.

Body length = 12.6-13.7 mm. Dorsal surface dark brown to black. Terminal maxillary palpimere cylindrical, as long as penultimate one. Pronotum black, rounded, narrower than that of the previous species (pronotum width / pronotum length = 1.24-1.29), widest near middle; pronotum completely smooth 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 narrower pronotum and lateral margins evenly curved, widest near middle.

Supplementary descriptions.

Male genitalia: in lateral view, median lobe of aedeagus with ventral margin very weakly curved near middle, apical lamella nearly straight; in dorsal view, median lobe of aedeagus with both lateral margins sinuate, widest near basal third, gradually constricted near apical third, apex rounded with apical lamella very short, apical orifice opened left-dorsally.

Remarks

This species was originally described from a single female. We herein provide the first record of the male of this species and provide description and illustration for the male genitalia.
