Platysympus brachyurus (Zimmer, 1907) Platyaspis brachura Zimmer, 1907: 374. Platysympus brachyurus. — Zimmer, 1913: 458–460, pl. 6 figs 56–58. Type material. Holotype: ZMB 18344, male. Winter Station, Antarctica, 66°02’S, 89°38’E. Diagnosis . Carapace without branchial swellings, without ridges, in lateral view without dorsal humps. Telson 2.0 pleonite 6, 0.6 uropod peduncles, without lateral setae. Adult male unknown. Depth. 385 m. Distribution . Antarctica, 55°2’S, 89°38’E. Remarks . As Day (1978) noted, this species is only known from a single, incomplete specimen, and thus the generic designation may not be correct. However, the most similar species is Platysympus phylloides , and it can be differentiated by the carapace. In P. phylloides the carapace is very flattened, and is at least as wide as long, while in P. brachyurus the carapace is not as flattened and is longer than wide.
