摘要：
Two undescribed and comparatively large species of the armored catfish genus Hypostomus were found in a recent field survey in a deep stretch canyon at the lower portion of the Rio Sao Francisco basin, in Bahia State, Brazil. One of these species is characterized by its few and sharp yellow dots over body and fins, its small mouth bearing few teeth and, the angled dentaries. The second species has remarkably short dorsal, pectoral, and pelvic fins and dark dots on body and fins. Both species are depth sheltered fishes with somewhat barrel shape and are formally described here.
