Abstract

A new species of Metapenaeus Wood Mason and Alcock closely related to M. suluensis Racek and Dall, from which it differs in having distinctly different thelycum and petasma, is described from Port Blair, Andamans. The diagnostic characters are: distomedian lobes of petasma broadly triangular with apices barely projecting beyond anterior margin of distolateral projections ; anterior plate of thelycum tongue-like with raised parallel lateral margins, lateral plates of thelycum flat, bounded posteriorly by two transverse protuberances bearing tufts of setae.
