Range extension of Guyanella clenchi (Altena, 1968) (Bivalvia, Lucinidae) with new records from Abrolhos Bank, Brazil

Abstract

Guyanella clenchi (Altena, 1968) is newly reported from Abrolhos Bank, northeastern Brazil. The new records extend the distribution of this species to the Southern Atlantic and reinforce the known overlap between the Caribbean and South American marine faunas. Even though it inhabits well-sampled regions, G. clenchi is a poorly known species which is not well represented in collections. The new occurrence of the species in the Southern Atlantic draws attention to the necessity of further improvement in sampling strategies aimed at filling in the distribution gaps of species.
