Distribution. Only known from the Córrego Santa Maria, tributary of the rio Iguatemi, right bank of the upper rio Paraná.

Remarks. Only two specimens of Corydoras sp. were captured in a tributary of the rio Iguatemi, in 2008 by V. F. B. Silva and collaborators. According to L. F. C. Tencatt (oral communication, 2011) this species is apparently new to science.
