Etymology: Pareiorhina: Greek, pareia = jaw + Greek, rhinos = nose (Ref. 45335); brachyrhyncha: Name from Greek adjective 'brachys' meaning short and 'rhynchos' meanig snout, muzzle; referring to the shape of the snout which is short relative to the width of the body and distinguishes this species from its congeners.

Morphology | Morphometrics
Vertebrae: 30. Diagnosed uniquely from its congeners by the reduction or absence of azygous plates in front of the nuchal plate. Differs further from its congeners by the presence of a minute lateral cusp in the teeth, wider body, anterior and lateral profile of head rounded, broad distal profile of the paired fins, and lower number of vertebrae (Ref. 56057).
Known from stony piedmont tributaries of the left bank of Rio Paraíba do Sul.
