Resumen
Two new species of aspredinid catfishes be- longing to the tribe Hoplomyzontini were collect- ed on expeditions to the Rio Napo basin, eastern Ecuador, in 1981 and 1983. Hoplomyzon papil- latus, new species, is distinguished from all known aspredinids by having ( 1 ) five stout papillae along the upper lip and (2) mentum with two pairs of ficadas con mas o menos 1 5 filamentos secunda- rios, (2) mas que 1 00 barbillas en el menton, pecho y vientre, (3) rama anterolateral del hueso pelvico expandida formando una placa superficial que se extiende anteriormente hasta encontrar el relativamente corto proceso coracoide, y (4) aleta dorsal i,7 (versus aleta dorsal i,l-6 en todos los otros aspredinidos). La tribu Hoplomyzontini es revi- sada y una clave de generos y especies es provista.
