Abstract:
Stenolicmus ix, new species, is described from Igarapé Curuá, left tributary of the Rio Amazonas, Pará, Brazil. It can be
distinguished from S. sarmientoi by the length of the nasal barbels that reach the base of the first opercular odontodes;
length of the maxillary barbels that reach the posterior margin of the opercular odontode plate; seven well-developed opercular
odontodes; seven well-developed interopercular odontodes; color pattern of the dorsal region of trunk composed of
agglomerated chromatophores forming circular patches twice the diameter of the eye; proportionally large eyes, 11.8%
HL; caudal peduncle tall, 11.6% SL, without dark bar at base of the caudal fin; length of the head proportionately larger,
17.9% SL; unbranched rays of caudal fin reaching distal margin of fin. Comparisons with other Sarcoglanidinae and
Trichomycteridae are presented. Some comments on the systematics and phylogenetic relationships of the group are made.
