Diploptera, also known as the beetle cockroach, is a genus of blaberid cockroaches. 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.[1] They are viviparous cockroaches and are therefore used for insect endocrinological studies.[2] There are eight known species and two subspecies.[1][3]
