Remarks. Colalongo & Pasini (1980) assigned this species to a new genus Typhloeucytherura based on its lack of an eyespot and considerable difference from the only blind cytherurine genus, Typhlocythere , then available to them. Maddocks & Steineck (1987) further identified certain unique carapace features of T calabra that might serve to distinguish the genus from Eucytherura . In our evaluation of species during this study we are unable to assign any of them confidently to Typhloeucytherura as presently diagnosed, formally or otherwise. We feel that the features identified as unique for Typhloeucytherura are variable in nature and serve to distinguish taxa only at the species level.

Distribution. The species is widespread in the deep-sea. In the Indo-Pacific material considered in this study the species has been recorded both at bathyal and abyssal site depths in the south-west Pacific: coretops TL 8730, TS 8648; Late Quaternary cores OSI 12-87112GC9, 13GC10, 1-86/6GC3, 6- 85/25GC18, Sonne 36-61; Pleistocene of DSDP Sites 207A, 209, 289; Middle Miocene to Pliocene of DSDP Sites 207A and 209; Late Oligocene to Late Pleistocene of DSDP Site 593; Late Eocene to Early Pleistocene of DSDP Site 592; Early Eocene and Late Oligocene of DSDP Site 277; Early to Middle Eocene of DSDP Site 207A; in the eastern Indian Ocean: Pleistocene of DSDP Sites 258 and 259. The species also occurs in the Mediterranean, Atlantic and Okinawa Trough.
