Rivulus unaensis, a new aplocheiloid killifish of the subgenus Atlantirivulus from eastern Brazil (Cyprinodontiformes: Rivulidae).Rivulus unaensis, new species, from Una, Bahia, eastern Brazil, is described. It is similar and possibly closely related to R. depressus by both possessing few mandibular neuromasts and the anterior portion of the trunk wider than deep. It differs from R. depressus in having fewer caudal-fin rays, fewer scales in the longitudinal series and more pelvic-fin rays.
