Overview

Kathirithamby (1990b) divides the family into 3 subfamilies (Corioxeninae, Triozocerinae and Uniclavinae) on the basis of the number of tarsi with or without claws, or with a claw-like structure in males.

Mandibles are absent in the males and the female cephalothorax is elongated and turned towards the host with a terminal brood-canal opening. Most species have been described from males attracted to light traps. Pentatomid, scutellerid, cydnid, coreid, and lygaeid bugs are recorded as hosts.
