[[ Corumbataia Britski ]]

The genus Corumbataia belongs to the Hypoptopomatinae, a group of small-sized armored catfishes composed by 17 genera and approximately 80 species (Schaefer, 2003; Ribeiro et al. 2005) distributed throughout cis-Andean South America from Venezuela to Northern Argentina (Schaefer, 1998).

Corumbataia was erected by Britski (1997) who defined the genus by the following combination of characters: exposed portion in the middle of the scapular bridge formed only by the coracoid (i.e., narrow cleithra which are covered by skin medially), compound hypurals 1 and 2 completely fused to the compound hypurals 3-5, atrophied maxillary barbel, and an infraorbital canal entering the infraorbital series via the pterotic-supracleithrum.

Corumbataia cuestae occurs in small streams of the Rio Tietê (upper Paraná basin), and C. tocantinensis occurs in the Rio Araguaia and Rio Tocantins. In this paper, we describe a third species of Corumbataia , from a headwater stream of the Rio Sucuriú, upper Paraná River Basin, Mato Grosso do Sul State, Central Brazil.
