Mandible molars well developed, of intermediate width between those of Typhlotanais and Leptognathia and always with ring of small apical spines. Pereopods 1–3 propodus longer than dactylus and unguis. Pereopods 4–6 propodus shorter than dactylus and unguis. Pleopods present or absent. Uropods stout and uniramous (although minute exopod process can be observed in some species), shaped as a pincer and consisting of one or two articles. Diagnosis, male. In general as the female.
