The genus Strebloceras Carpenter, 1859 is comprised of very small species, characterized by a tubular shell with trochospiral protoconch that is retained during all the lifetime. Only few species are known, most of which fossil, spanning from early Eocene to Recent.
A revision of the genus, mainly based on type material, is presented. The type material of †Strebloceras cornuoides Carpenter, 1859, ... [Show full abstract] †Caecum (Strebloceras) lituus Deshayes, 1861, †Caecum carpenteri Desha- yes, 1861, Strebloceras subannulatum de Folin, 1880, †Caecum bezanconi Cossmann, 1888 and †Stre- bloceras hinemoa Finlay, 1931 is illustrated.
It is shown that Caecum (Strebloceras) lituus Deshayes, 1861 belongs to Caecum (s. str.). The new combi- nation †Parastrophia soluta (Carpenter, 1859) is proposed. Further, the Recent species Strebloceras pizzinii n. sp. is described as new.
