Description: Trichomycterus jacupiranga differs from all other species of the subfamily Trichomycterinae by the following unique combination of characters: first pectoral-fin ray prolonged as short filament (vs. not prolonged), one supraorbital pore s6 fused (vs. two supraorbital pores s6 paired), pectoralfin rays 8 (vs. 7 or 6), pelvic fin covering anal and urogenital opening (vs. not covering), anal and urogenital opening closer to anal-fin origin than to pelvic-fin base (vs. midway between anal-fin origin and pelvic-fin base), caudal fin truncated with attenuated edges (vs. rounded or truncated without attenuated edges), and the following morphometric characteristics: head length 20.7-22.4 % SL, and head width 90.6-104.6 % HL. (Wosiacki et al. 2005). Habitat: Known only from the type locality of the Rio do Queimado, Parque Estadual de Jacupiranga, Cajati [São Paulo, Brazil], (Wosiacki et al. 2005). Diet: Will feed on most aquarium fare such as tablet, frozen and live foods. It is an opportunistic predator that mainly feeds on insects, but also will take small crustaceans and plant material (algae and remains of phanerogams). Etymology: The species name, jacupiranga, refers to the type locality, Parque Estadual de Jacupiranga, município de Cajati, São Paulo, Brazil. Jacupiranga is also the indigenous Tupylanguage name for a species of bird native to the region (Penelope obscura - Cracidae), commonly known as the dusky-legged guan, and comes from yaku (a bird) and piranga (red). Treated here as a noun in apposition.
