Differential diagnosis

This species is very close to C. indica d’ Orchymont, 1920 . It can be distinguished from the latter by elytra with more or less distinctly yellow-brown patch mediobasally ( Figure 4a, e ), apical yellow patch covering at least one-quarter of elytra ( Figure 4a,e ); aedeagus with parameres broader ( Figure 6e ).

Distribution

China, Thailand ( Hebauer 1995; Hansen 1999). First record for China ( Figure 7 ).
