Trichomycterus mariamole Barbosa & Costa, 2010 Figure 3C

Geographic distribution: Piraí river drainage and upper reaches of Alambari and Barreiro rivers, Paraíba do Sul river basin.

Diagnosis: Trichomycterus mariamole has light yellow background coloration with small circular brown marks on flanks, diameter of the eyes 9% to 11% of HL, opercular region of odontoids reduced and laterally positioned, and 7 pectoral fin rays ( Barbosa and Costa 2010). Trichomycterus mariamole differs from T. claudiae , a species that occurs in the middle portion of the Piraí drainage, by the short ill-defined stripe restricted to the anterior portion of the flank (vs. well defined stripe along the whole flank) and fewer interopercular odontodes (27– 34 vs. 41–46).
