ResumoThe first two specimens of Regalecus glesne Ascanius, 1788, collected in the Argentine Sea, at Playa Unión beach, 43º 18' S, 65º 02' W are reported. Body measurements, meristic characters and morphological data are given. The most important differences with two other regalecid species, R. russelii Cuvier and R. kinoi Castro-Aguirre et al. 1991, from the Pacific coasts of Mexico, are considered. Also, a specimen caught at 43° 03’ S, 59° 14’ W, at 993 m depth, previously identified as Agrostichthys sp. is rediagnosed as Agrostichthys parkeri Benham, 1904. The distribution of R. glesne is extended to the Argentine Sea, adding a regalecid species to its fish fauna.
