摘要：

Trichomycterus macrophthalmus, new species is described from the upper Paraiba do Sul river basin, southeastern Brazil. It differs from all species of Trichomycterus from southeastern Brazil by possessing nine pleural ribs. Trichomycterus macrophthalmus is similar to T travassosi from the same basin by both owning short nasal barbel, but the new species can be easily distinguished from it by head width, eye size, and colour pattern. The new species belongs to the T travassosi species complex by displaying transverse dark marks on the dorsum.
