this margin is more sinuous as it has a median indentation plus paired lateral indentations which produce the appearance of angular posterolateral corners. The new species differs from both of these species in having an almost linear, truncated rear margin with just a tiny median indentation. These differences are sufficient to justify the establishment of a new species.

The male was lodged inside a chamber enclosed laterally and ventrally by the sclerotized exopods of the third legs and dorsally by the unsclerotized third leg endopods plus the lamellate fourth legs which together form a horizontal internal wall separating the male from the dorsally-located, upper chamber containing the loosely coiled egg strings. The partitioning of the brood chamber into a dorsal space enclosing the egg strings and a ventral space housing a single adult male has not been reported before for any
