. The two animals share the following unique features: the antennule of males have two long straplike plumulose setae and similarly shaped dactylus; antennae have an anterior seta on endopod segment 1; the coxa of maxilliped is fimbriate and the area of denticulate pegs on P1 endopod is similar; the unusual shape and setation of P3 endopod and male P5 are virtually identical. However, the following significant differences show that the two species are distinct:

The significance of these differences will be considered in the discussion.
