Type species

Minicorydia maoxiana Qiu, Che and Wang sp. nov. – here designated.

Diagnosis

The females of Minicorydia Qiu, Che and Wang gen. nov., Therea Billberg and Ergaula are all beetle mimics. According to the definition by Rehn (1951), they should all belong to the tribe Corydiini because the females are winged. Other characters they have in common are the thick tegmina, and the protruding but not valved media of subgenital plates. The female Minicorydia can be easily distinguished from the latter two by its distinctively small body (10.0 mm); unicoloured brown overall colouration; and pronotum and tegmina with short, dense pubescence. Female Therea are characterised by their large (about 17.5–24.0 mm) and round body; pronotum with long setae; and tegmina with large bright spots. Female Ergaula are characterised by their larger (25.0–36.0 mm) and oval body; extremely thick pronotum with dense protuberances; and unicoloured tegmina.
