Abstract

Two similar species of Sphaeroma (Sphaeromatidae: Isopoda) are studied and described from two different Oceans. Sphaeroma annandalei Stebbing, 1911 is redescribed from different localities of the Indian Ocean, and Sphaeroma silvai sp. nov. is described from the South Atlantic Ocean. Sphaeroma silvai sp. nov. is easily distinguished from S. annandalei by its pereopod 5, where the basis carries a well extended inferior lobe; the shape of the pleotelson and the tuberculation of pereonites and pleon. Both species are distinguished from other species of the genus by transverse ridges on their pereonites. The known distribution of S. annandalei is limited to the northern areas of the Indian Ocean, from the Persian Gulf to Malaysia.
