Trichomycterus nigroauratus Barbosa & Costa, 2008 View in CoL Figure 3E

Geographic distribution: Upper Piraí and Barreiro

river drainages in the Paraíba do Sul river basin.

Diagnosis: Trichomycterus nigroauratus differs morphologically from T. mariamole and T. macrophthalmus by the presence of golden spots on the snout and body, and broad (wider than long) metapterygoid bone ( Barbosa and Costa 2008). Trichomycterus nigroauratus presents ontogenetic variation of coloration, with juveniles exhibiting a black stripe along the lateral midline, and adults presenting stripes with irregular borders and dark stains that can cover the entire body in a homogeneous pattern ( Buckup et al. 2014).
