Description (holotype only). Body length 10.2 mm (including mandible), width 3.9 mm. Black, mandible and labrum brown, palpi, antennae and legs pale yellow. Eyes large, longitudinal diameter of eye 3.6 times as long as tempora; relative length of scape and antennomeres II–VI as follows: 1.00: 0.43: 1.71: 1.36: 1.07: 1.07. Pronotum cordate, wider than long, widest at apical one-fifth, wider than head, PW/HW ¼ 1.14, PW/PL ¼ 1.45, PW/PAW ¼ 1.52, PW/PBW ¼ 1.55; anteriorl angle round; basal angle acute and projected laterad; lateral margin with 2 setae, 1 at apical one-fifth and the other at basal angle. Elytra subovate, much wider than pronotum, EL/EW ¼ 1.67, EW/PW ¼ 1.69; stria deep; interval III with 3 setiferous pore punctures; elytral apex at sutural angle rounded. Prosternum, metasternum, and pro- and metepisterna impunctate. Sixth visible sternum with 4 marginal setae in male and 8 in female.

Distribution. Known from Vietnam, China (including Taiwan), and South Korea.

Remarks. We compared the type of O. vietnamicus Kasahara with that of O. sinensis Bates and found no significant differences. Dr. Jong Cheol Paik provided two pairs of Onycholabis uenoi Paik and Lafer collected from the type locality and determined by him; and, as with O. vietnamicus , we were unable to find any important differences from the type O. sinensis Bates.

Kasahara (1986:75) indicated that O. sinensis adults lacked setae at the basal pronotal angles (based on Taiwanese specimens, but not on the type). This error led him and, subsequently, Paik and Lafer to describe new species ( O. vietnamicus and O. uenoi , respectively) which are both junior synonyms of O. sinensis . Furthermore, Dr. Ge Siqin kindly helped us by checking all four Taiwanese specimens labeled O. sinensis in MNH. She found that all had setae at the basal pronotal angles, except for one in which the seta was broken and missing, but the pore puncture remained.
