The fasciolariid gastropod genus Benimakia:: New species and a discussion of Indo-Pacific genera in Brazil

Benimakia Habe, 1958, is a distinctive genus, of Fasciolariidae. Its type species, the Indo-West Pacific Recent B. rhodostoma (Dunker, 1,860), is distinct from Turbinella fastigium Reeve, 1847, which is here also assigned to Benimakia and with which B. rhodostoma was often confused. We describe B. delicata n. sp. from Samoa and tentatively assign the Brazilian Latirus ogum Petuch, 1979 to Benimakia. At least two Indo-Pacific genera of gastropods besides Benimakia (Caducifer and Quimalea) also contain isolated Brazilian species., How and when these genera reached Brazil, and why many Indo-Pacific genera that have invaded, the eastern Pacific do not occur in Brazil, remain unanswered questions.
