Thrombasia rotundata (K.H. Barnard, 1925) comb. nov. Lakota rotundatus K.H. Barnard, 1925: 329.―J.L. Barnard, 1967: 38 (table 1). Chironesimus rotundatus .―J.L. Barnard, 1962: 22, fig. 3. Schisturella rotundata .―J.L. Barnard, 1967: 72 (key).― Larsen, 2007: 14 (key). Types. Syntypes, 12 specimens, SAM A2813, SAM A4545, SAM A5910. 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). : Published as part of Kilgallen, N. M. & Lowry, J.
