Maxilla 2 elongate. Maxilliped with very thin plates, palp absent or 1–2-articulated. Coxae 1–3 narrow, coxae 1 and 4 shorter than coxae 2–3. Gnathopods feeble, simple; gnathopod 1 ischium, carpus and propodus elongate, dactylus very short, usually with several feather setae; gnathopod 2 carpus and propodus elongate, merus and carpus produced posterodistally, dactylus very short, usually with robust seta.

Uropod 1 biramous, outer ramus subequal to or slightly shorter than inner ramus; uropod 2 biramous, outer ramus shorter than inner ramus; uropod 3 biramous or uniramous, in biramous uropod 3, outer ramus usually shorter than inner ramus. Telson entire, tip acute or rounded.</p> <p>Remarks. On the shape of the gnathopod 2, J. L. Barnard and Karaman (1991) stated “... simple, otherwise... carpo- or merochelate.” However, it should be unified to “simple”, because the shape is quite different from the true “carpochelate” (ex. Grandidierella Coutière, 1904) and “merochelate” (ex. Aora KrØyer, 1845 and Aoroides Walker, 1898) (see Ariyama and Kohtsuka 2022).</p> </div>	https://treatment.plazi.org/id/560A8789FF84FFDFFC02FAD3FDA8FC7F	Public Domain	No known copyright restrictions apply.
