distinguished from Gonodactylus chiragra by the presence of five instead of three carinse 
on the median protuberance of the telson, and by the presence of acute spines on the 
posterior ends of three of them, by the possession of six instead of four spines on the 
posterior border, and by the presence of a tooth on the inner edge of the outer spine of 
the ventral prolongation of the uropod. It is more difficult to distinguish it from 
Gonodactylus glabrous, which it resembles very closely. The many minute differences 
will be pointed out in the description of this species.
