  • Presence of the marine catfish Genidens planifrons (Teleostei, Siluriformes, Ariidae) inArgentinean shores. The marine catfishes of the genus Genidens are endemic of the south Atlantic coasts ofSouth America. The clade is composed by four extant species, distributed from the southern coast of Brazil tonorthern Patagonia, though some species can occasionally be registered in southern Patagonia. The presence ofthe species Genidens planifrons in Argentinean shores is confirmed on the basis of new records. The taxonomicalidentification of this species is sustained by a series of reliable morphological and osteological characters. Thepresence of this species in Argentinean territory considerably extends its southern distribution.
