The distinguishing feature of this species is the reduction in the setation of the endopod of the maxilla: it has an armature formula of 1, 1, and 3 on the first to third segments. This is the most extreme reduction found in any described species, including the additional new species described below. All other species possess a total of between 6 and 8 setae on the maxillary endopod compared to the 5 setae retained in

). The armature formula of the 3-segmented maxilliped is also unique: the first to third segments carry 5, 1, and 6 setae, respectively. The third exopodal segment of legs 2 and 3 carries 3 spines and 6 setae, and in leg 4 it carries 2 spines and 6 setae. In each of these legs the terminal spine is setiform, but its derivation from the terminal spine is indicated by the plumose ornamentation along the inner margin only.
