See text Diploptera, occasionally called beetle cockroaches, is a genus of blaberid cockroaches in the monotypic subfamily Diplopterinae.

Cockroaches of this genus resemble beetles, with hardened tegmina and cross-folded hindwings.

They live in tropical forests in South China and Southeast Asia, and Pacific islands including Hawaii.
