Record of Electrona paucirastra Bolin, 1962 (Pisces: Myctophiformes: Myctophidae) in Brazilian waters, with comments on the occurrence of Electrona risso (Cocco, 1829) in the western South Atlantic

Abstract

Electrona risso, a warm circumtropical lanternfish species distributed in all oceans, has been reported in the western Atlantic from Suriname to Southern Brazil. Re-examination of specimens attributed to this species which presumably supported the southernmost record in the western South Atlantic and are available at Museu de Zoologia, Universidade de São Paulo, Brazil, revealed that they were misidentified and are really Electrona paucirastra. As a result, E. paucirastra is reported for the first time in southern Brazil and the distribution of E. risso in the western Atlantic is discussed.
