Abstract

A new species of the isopod genus Stenetrium Haswell, 1881, is described from Navassa Island, Caribbean Sea. The new species, S. kensleyi, is compared to S. serratum Hansen, 1905, the only congener known from the western Atlantic following recent revisions of the Stenetriidae (Serov and Wilson, 1995, 1999; Bolstad and Kensley, 1999), and to some members of the recently proposed genus Hansenium, with which it shares several characters. The new species differs from S. serratum (and from other members of the genus) in its possession of an unusual male first pereopod, which has a greatly inflated dactylus, broadly triangular propodus, and a medial sharply triangular shark-fin-shaped tooth on the propodal cutting border.
