Abstract: Three new species of Venustatrochus Powell, 1951 Powell, A.W.B. (1951) Antarctic and subantarctic Mollusca: Pelecypoda and Gastropoda. Discovery Reports 26, 47–196. doi: 10.5962/bhl.part.16335[Crossref] , [Google Scholar], V. eclectus n. sp., V. galateae n. sp. and V. youngi n. sp. are described from New Zealand, and Calliostoma (Benthastelena) malaita Vilvens, 2009 from the Solomon Islands and Norfolk Ridge and C. atlantis Clench & Aguayo, 1940 from off Cuba are referred to the genus. The radula of the type species of Otukaia, O. kiheiziebisu (Otuka, 1939), is illustrated, and O. ikukoae Sakurai, 1994 is resurrected from synonymy under O. kiheiziebisu and transferred to Tristichotrochus Ikebe, 1942. Benthastelena Iredale, 1936, Fautor Iredale, 1924 and Maurea Oliver, 1926 are each assigned genus rank in Calliostomatinae, and Alertalex Dell, 1956 is treated as a subgenus of Maurea. The South American species Otukaia chilena (Rehder, 1971) and O. delli (McLean & Andrade, 1982), the western subantarctic species O. eltanini Dell, 1990 and Calliostoma muriellae Vilvens, 2001 from Madagascar are referred to Maurea. Otukaia crustulum Vilvens & Sellanes, 2006 is referred to Calliotropis L. Seguenza, 1903 (Calliotropidae). Six new species of Falsimargarita Powell, 1951 are described—F. callista n. sp., F. challengerica n. sp., F. eximia n. sp. and F. tangaroa n. sp., from New Zealand, F. kapala n. sp. from southeastern Australia, and F. coriolis n. sp. from New Caledonia. Calliostoma atlantoides Quinn, 1992 and C. coronatum Quinn, 1992 from off the Lesser Antilles and Brazil, respectively, are referred to Falsimargarita. Phenacomargarites n. gen. is introduced for P. williamsae n. sp. from the Solomon Islands, and P. incomptus n. sp. and P. titan n. sp. from the New Zealand region. Phenacomargarites, Falsimargarita, Selastele Marshall, 1995 and Fautrix Marshall, 1995 are referred to subfamily Fautricinae Marshall, 1995 (elevated from tribe level).http://zoobank.org/urn:lsid:zoobank.org:pub:09EAD861-3B62-42F9-BCC1-453EBE1347D4
