Otitoma Jousseaume, 1898: 106 View in CoL . Type species (virtual tautonomy) Otitoma ottitoma Jousseaume, 1898 View in CoL .
Thelecytharella Shuto, 1969: 208 View in CoL (as subgenus of Euclathurella View in CoL ). Syn. n. Type species (o.d.) Agladrillia oyamai Shuto, 1965 , Miocene of Philippines (and Japan).
[Junior synonyms of Thelecytharella Shuto, 1969 View in CoL , were listed by Kilburn (1995: 262).]
Remarks: Although Powell (1966: 126) regarded Otitoma as a nomen dubium, its type species can now be recognised and proves to be a synonym of the widely distributed Pleurotoma cyclophora Deshayes, 1863 . Powell (1966) and others have referred P. cyclophora to Daphnella Hinds, 1844 , subgenus Hemidaphne Hedley, 1918 . However, the threewhorled protoconch is domed, with protoconch II smooth, except for a few arcuate axial riblets near its termination and extremely minute granular sculpture, and totally lacks the diagonally reticulate sculpture, characterisitic of the genus Daphnella . In overall characters, P. cyclophora agrees well with members of the group previously called Thelecytharella (see Kilburn 1995), over which Otitoma clearly has priority. The radula of this genus remains unknown.
Daphnella crenulata Pease, 1868 ( Fig. 14 View Figs 9–14 ), is based on a juvenile of Otitoma cyclophora View in CoL . Although Powell (1966) referred D. crenulata to Antimitra Iredale, 1917 View in CoL , that taxon has been muchmisunderstood, and in fact its type species, Pleurotoma aegrota Reeve, 1845 , shows no characters indicative of a turrid genus. The two syntypes ( Fig. 1 View Fig ) appear to be based on juveniles of a species of Metula Adams & Adams, 1853 View in CoL , family Buccinidae View in CoL .
Of described turrids, I refer the following Recent species, which have been distributed in the published literature amongst a wide range of different genera, to Otitoma View in CoL . I have examined types of all species, with the exception of Hemidaphne gouldi View in CoL for which
SEM’s are available. Literature references to these taxa are omitted, as these can be found in Tucker (2004). carnicolor Hervier, 1896, Drillia crenulata Pease, 1868 , Daphnella [= Pleurotoma cyclophora ] crokerensis Shuto, 1983, Austropusilla (Metaclathurella) cyclophora Deshayes, 1863 , Pleurotoma gouldi Yen, 1944 , Hemidaphne [synonym Mangelia pura ] kecil Sysoev, 1997, Thelecytharella kwandangensis Schepman, 1913 , Drillia lirata Reeve, 1845 , Pleurotoma metuloides Kilburn, 1995 , Thelecytharella mitra Kilburn, 1986 , Mitrellatoma oneili Barnard, 1958 , Drillia ottitoma Jousseaume, 1898 , Otitoma [= Pleurotoma cyclophora ]

Although Otitoma ottitoma View in CoL is synonymised with O. cyclophora , the following description is based on the ottitoma View in CoL morph, primarily on series from Mozambique, which agree well with the neotype.
