Description
The proportional lengths of the cephalothorax and abdomen are 5.0: 1.The 1st antenna reaches back to the middle of the abdomen and consists of 23 free segments, segments 8 and 9 and 24 and 25 being fused. In the maxilla the number of setae on the basal segment and on the endopod are few.Marked protuberance on the left side of the genital segment of the abdomen, extending back to the posterior margin.
In the immature male, the general structure closely resembles that of the immature female, but exhibits certain small differences. The 2nd antenna shows certain differences from the female, especially as regards the endopod, which in this sex is much longer and is of stouter build. A rudimentary 5th pair of legs is present. Each limb consists of two basal segments, a long exopod and a short endopod; the limb of the right side is well developed and is nearly twice the size of that of the left side; both endopod and exopod are well developed, the former being crowned by a crescentic plate, while the latter tapers to a point.
