Abstract
A new Hypoptopomatinae, Corumbataia britskii, is described based on specimens recently collected in a tributary of the
upper Rio Paraná basin, Mato Grosso do Sul State, Brazil. Corumbataia britskii differs from its congeners by having a
more depressed head profile (vs. a more rounded head profile in C. cuestae and C. tocantinensis), by having a more
developed and conspicuous tuft of enlarged odontodes on the tip of the supraoccipital (vs. its reduced condition found in
C. cuestae and C. tocantinensis), and by heaving a partially enclosed arrector fossae (vs. an almost completely enclosed
arrector fossae in C. cuestae and C. tocantinensis).
