Abstract
The genus Athleta Conrad 1853 is briefly discussed and the following are regarded as synonyms; Volutocorbis Dall 1890, Volutopupa Dall 1890, Neoathietu Bellardi 1890, Volutospina Newton 1906, Notoplejona Marwick 1926, Eoathleta Gardner 1945, Volutovetus Pilsbry and Olsson 1954 and Bendelutu Eames 1957. Ternivoluta Martens 1897 is regarded as a subgenus of Athleta, and Austrovoluta Cotton 1949 is shown to be a synonym of the former. Ternivoluta is restricted to Australia and ranges from Upper Eocene to Recent. A lineage in the subgenus from Upper Eocene to Upper Miocene is reported. A. (Athleta) wangerrip (Upper Paleocene), A. (Ternivoluta) curvicostata (Upper Eocene), A. (T.) anticingulata craticula (Lower Miocene), A. (T.) subcrenulifera (Lower Miocene) and A. (T.) bungae are newly described from Victoria, Australia and five other species and subspecies are redescribed.
