Tetracona Meyrick, 1884

Tetracona Meyrick, 1884: 307; Chen et al. 2017: 215. Type species: Aediodes amathealis Walker, 1859, by monotypy.

Differential diagnosis.

The species of Tetracona Meyrick, 1884 are similar to the members of Agrotera Schrank, 1802 in their external characters. However, they can be easily distinguished from the latter by using the male genitalia: The uncus of Tetracona is lobe-shaped, laterally covered with dense setae; the valvae are basally equipped with a bundle bristles near the middle, and are elliptical with blunt rounded apices. In Agrotera , the uncus is short to elongate and conical, set with few setae; the valvae have a large, hook-like process near the base, and are elliptical with narrow and pointed apices ( Chen et al. 2017).

Distribution.

Australia, China.

Remarks.

This genus is recorded from China for the first time herein.
