Diagnosis [modified from Hansen (1890)]. Head without tubercles, continuous eyes, except small anterior median area.Frontal lamina linguiform, longer than wide, narrower in the middle and slightly rounded apex ( Fig. 17 View Figure 17 ). Antennular peduncle with article 1 not dilated. Antenna reaching pereonite 2. Pereon dorsally smooth. Pleon with few tubercles. Pleotelson narrow, long, without lateral incisions, with median groove; distal margin rounded, crenulated, apical crenulations more developed; anterior margin with four very small tubercles, without lateral incision. Uropods reaching apex of pleotelson.

Remarks. Lemos de Castro and Lima (1971) redescribed this species based on material collected in Amapá (02°57’N 49°04’W). In this description, they stated that the pleotelson has a lateral incision; however in their figures 35 and 36 the lack of any incision mentioned in their description is clear (p. 153). Additionally, the lateral incision is absent in the original description of Hansen (1890), as well as in the material studied herein.
