Type locality. 36 miles east to north-east of Cape Point , South Africa , 650–800 fathoms [ 1189–1463 m ] . Depth range. 1189–4050 m (K.H. Barnard 1926, J.L. Barnard 1962 ). Remarks. This species is poorly known, however in the original description of the species K.H. Barnard (1926) specified “ side-plate 1 subtriangular, inferior angle sub-acute… first gnathopod, 6 th joint a little shorter than the 5 th ”. Furthermore, J.L. Barnard (1962) illustrated the gnathopod 1 coxa as being only slightly shorter than the coxa of gnathopod 2 (vestigial in Schisturella ). This combination of characters indicate that this species is more properly placed in Thrombasia . Distribution . South Atlantic Ocean . Cape Point, South Africa (K.H. Barnard 1926); Cape Basin (J.L. Barnard 1962 ).
