Ptereleotris randalli n. sp., the third species of the genus from the Western Atlantic, is described from the Brazilian Coast. It differs from P. helenae, its North Atlantic sister species, in having the second dorsal and anal fins comparatively lower and slightly more elevated anteriorly; a shorter caudal fin with the fifth and sixth rays prolonged as filaments; and shorter pelvic fins which are about the same length as the pectorals. This species is known from Parcel de Manuel Luiz (00°52’S, 44°16’W), NE Brazil to Alcatrazes Archipelago (24°06’S, 45°42’W), SE Brazil, in depths between 8 and 60 m.
