The subfamily is distinguished from the other subfamilies (Thoracostopsinae and Trileptiinae) by the three broad mandibles in the buccal cavity, each formed by of two rods with a thin membrane between them, and by a strongly sclerotized cephalic region with three lips and protruding cephalic setae (Lo Russo et al., 2012).
