| Note the interarticular membranes between the segments of the endopodites and the blade-like set of the exopodites. |
| Another distinguishing characteristic is the lack of asymmetry in the setation of the exopodites of the 1st maxillipeds of these larvae with respect of other brachyuran crabs. |
| They may have rudimentary exopodites, and may or may not have branchial filaments or lamellae developed on their posterior faces. |
