Abstract

Parelasmopus setiger has been widely described from tropical to subtropical regions from Philippine Islands, Sulu Sea, Indonesia, Australia, north Indian Ocean and the Seychelles by several authors. The present study provides detailed descriptions of Parelasmopus setiger Chevreux, 1901 (Crustacea: Amphipoda) based on newly collected specimens from Pulau Hantu, Singapore. Morphological characters of the specimens closely resemble those of Parelasmopus setiger and Parelasmopus siamensis Wongkamhaeng, Coleman & Pholpunthin, 2013. The specimens of both the species were quite similar to the Singapore specimens, although the shapes of appendages vary with growth and locality; therefore, P. siamensis is synonymized with P. setiger. The following species characteristics for P. setiger are indicated: 1) antenna 1 peduncle with 2 setae; 2) male gnathopod 2 propodus palm transverse; 3) Pereopods 5 to 7 posterior margins with long slender setae; and 4) dorsal carina pattern for pereonite 7 and pleonites 1 to 3.
