A revision of the species of Bolma Risso, 1826 (Gastropoda: Turbinidae)
Abstract
All Australian and New Zealand fossil taxa and all world living taxa are revised in the genus Bolma Risso (= Oobolma Sacco, = Ormastralium Sacco, = Tylastralium Sacco, Pseudastralium Schepman, = Incilaster Finlay, = Galeoastraea Habe, = Hirasazaea Habe). The genus is contrasted with related genera using shell and radular characters, and all recognised taxa in Bolma are diagnosed and figured. New taxa named are Bolma anacanthos n. sp., Oligocene, Victoria; B. austroconica n. sp., Oligocene, Victoria; B.flindersi darraghi n. subsp., Upper Eocene, Victoria; B. kermadecensis n. sp., Recent, Kermadec Islands; B. somaliensis n.sp., Recent, East Africa; and B. tamikoana flava n. subsp., Recent, Malagasy Republic. Senobolma Okutani, 1964 is ranked as a subgenus of Bolma Risso. Living taxa newly recorded from Australia are B. guttata millegranosa (Kuroda & Habe), B. guttata subsp?, B. henica (Watson), and B. tamikoana tamikoana (Shikama).
