Exopod clearly demarcated from baseoendopod and armed with three setae: the innermost seta subequal in length to middle seta and longer than outermost seta. Surface of exopod with a small pore located near the insertion point of the surface seta.

species typically have three, but sometimes two. The endopodite has only seven setae, a reduction from the typical ten setae. The coxal gnathobase is also extremely well developed, being larger than the basis, exo- and endopodite combined. The syncoxa of the maxilla also possesses only one of the three endites, although one of the missing two endites is represented by a seta. The maxillula also shows reduction in the number of setae, with the coxa wanting and the absence of a suture between the exopod and the basis. The syncoxa of the maxilliped also has no seta, which is unique within the genus
