Type species

Acosmetides peltates gen. et sp. nov.

Diagnosis

The new genus resembles the genus Acosmetura Liu, 2000 , but differs from it in the following characters: male tenth abdominal tergite protruded backwards with posterior margin split or concave; subgenital plate with basal area broad, apical area narrow, with a median lobe.

Etymology

The name of the new genus is derived from the genus name Acosmetura and the Greek ʻ -ides ʼ, meaning ʻalikeʼ. The Chinese name of the genus is ffi异ffl尾ễh (Ni Yi Shi Wei Zhong Shu).

Tegmina short, apices surpassing posterior margin of pronotum, or concealed beneath pronotum. Foretibial tympana open and oval on both sides. Genicular lobes of hind femur rounded, without spines. Male tenth abdominal tergite slightly elongated, posterior margin concave, or split; genitalia sclerotized, short; cercus medium long, usually dorsal surface of the middle area concave downwards, apex upcurved; subgenital plate with broad basal area, apical half narrow, only with a median lobe.
