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.^[1]^[2] They are viviparous cockroaches and are therefore used for insect endocrinological studies.^[3]
