Cerithiopsis flava (C.B. Adams, 1850) is spread in the Caribbean region and

adjacent areas of Florida, Venezuela, Aruba, Curacao and Virgin Islands but, until

this moment, it had not been reported for the east coast of South America. We

have examined material of the family Cerithiopsidae from several Malacological

Colections such as: MORG: Museu Oceanografico de Rio Grande, IBUFRJ: Instituto

de Biologia da Universidade Federal do Rio de Janeiro, MZUSP: Museu de Zoologia

da Universidade do Estado de Sao Paulo, UNICAP: Laboratory of Zoology of

Universidade Catolica de Pernambuco, and MNHN: Museum National de Historia

Natural. The species Cerithiopsis flava, probably a grazer on sponges and algae, can

be characterized by slender conic shells with strong axial and spiral sculpture and a

diagnostic protoconch with about 6 whorls and a dark pointed tip. We present here

the first record of this species for Brazilian waters, where it occurs widely

distributed: Amapa, Pernambuco, Alagoas, Bahia, Espirito Santo, Rio de Janeiro,

Sao Paulo and Santa Catarina. We have also detected a wider batimetric range than

previously reported in literature: from 1 to 175m.
