Material.

Remarks.

The specimens seem referable to the Gitanopsis pusilla without much doubt. In amphilochid amphipods, most species descriptions are based only on females, since the collection of males is rare. The female gnathopods are typical among amphilochids in having a distally dilated propodus, an evenly convex palm and an elongate carpus. The specimens at hand are clearly related to the eastern Pacific species ( K.H. Barnard 1916) in bearing the accessory flagellum of antenna 1. Ortiz and Lalana (1997) have reported Gitanopsis pusilla and Gitanopsis antipai from the neighbouring waters of Bunaken, Indonesia. In their illustration of Gitanopsis antipai , the species is set apart from Gitanopsis pusilla by the lack of an accessory flagellum, the relatively slender basis of pereopod 7 and the less spinose uropods 1-2.
