REMARKS

Ethusa magnipalmata View in CoL is thus far known only from the male holotype (MNHN-B 21594). It is almost undistinguishable from Ethusa orientalis Miers, 1886 View in CoL , except for the morphology of its G1. Each pleopod has a large notch on the distal third of its length and a pointed, knife-like tip ( Chen 1993: fig. 7e). The notch, however, most probably resulted from the insertion of the G2. The relatively large overall size of the holotype is evidence that the specimen is not the juvenile stage of another species. The anterior border of the endostome reaches the proximal border of the antennular fossae of the basal antennular articles. The holotype was collected from the Loyalty Is, a location where E. orientalis View in CoL is known to occur (see Remarks of E. orientalis View in CoL above).
