Abstract
A new species, Steindachnerina notograptos, is described from the middle portions of the Rio Tocantins drainage, Brazil. The possession of a small, fleshy, lobulate body situated on each side of the posterior limit of the medial fold of the buccopharyngeal complex is autapomorphic for S. notograptos. The combination of other aspects of the buccopharyngeal complex along with meristic and pigmentation features further distinguish the species from all of its congeners.
