Introduction
This small group is related to the Cyclodorippidae, and indeed, has been long treated as a synonym of that family. Cymonomids are rarely collected except by dredge from deeper waters of the continental shelf and slope. Only one genus and four species are known from deep water off eastern Australia. Cymonomus delli Griffin & Brown, 1976, previously recorded from Australian waters under the genus Cymonomoides was transferred back to Cymonomus by Ahyong & Ng (2009). A modern treatment of the family is available in the works of Tavares (1993a, 1993b).
Diagnosis
Carapace subquadrate, longer than wide; orbits absent. Third maxillipeds elongate, completely covering buccal cavity; exopod of third maxilliped with flagellum. Pereiopods without movable articulation between basis and ischium; first two pairs long and thin, subequal; fourth and fifth pereiopods reduced and positioned dorsally. Female with sternal grooves. First abdominal segments visible dorsally; uropods absent. Genital openings coxal, female on third pereiopods, male on fifth pereiopods.
