Differential diagnosis

This species can be distinguished from other known Oriental species by dorsum entirely black, labrum uniformly black. Pronotum with distinct anterior angles, posterior angles not acute ( Figure 1a View Figure 1 ), lateral stria continued along anterior margin and distinctly curved behind eyes ( Figure 1e View Figure 1 ). Elytra with almost regular series of punctures, intervals with coarser and more irregular punctures ( Figure 1d View Figure 1 ), clearly deflected lateromedially, sutural striae reaching two-thirds anteriorly ( Figure 1d View Figure 1 ), only narrowly yellow apically and posterolaterally ( Figure 1b,d View Figure 1 ). Median lobe of aedeagus broad and round apically, parameres rounded apically ( Figure 6a,b View Figure 6 ).

Distribution

Widely distributed from south-eastern Asia through Vietnam to Nepal ( Hansen 1999) and China (Hong Kong, Hainan, Macau, Jiangxi, Yunnan). First record for China ( Figure 7 View Figure 7 ).
