Brachytrycherus curviantennae Chang, Bi & Ren, 2016 Figs 15, 16A, C

Brachytrycherus curviantennae Chang et al., 2016: 139.

Diagnosis.

Brachytrycherus curviantennae is similar to B. humeralis and B. denticulatus sp. nov. in both bodies being broadly oval, elytral maculae transverse, pronotum sides strongly curved. However, antennomere 3 distinctly curved outwards and elytral maculae nearly cymbiform can distinguish B. curviantennae from all its congeners.

Length.

Biology and ecology.
