Abstract—

This paper reports on the first record of the bristlemouth Margrethia valentinae Parin, 1982 (Stomiiformes: Gonostomatidae) in the western South Atlantic, based on a single specimen (NPM 6856, standard length 52 mm) bottom trawled off Santa Catarina, Brazil, at 26°23′25′′ S, 46°01′50′′ W, 400 m depth, on December 13, 2000. Morphometric and meristic data for M. valentinae and its congener, M. obtusirostra, are given and compared to those reported in the literature. Remarks on the taxonomy of the genus Margrethia and an overview on its distribution are also provided.
