摘要：
Knodus tiquiensis, new species, is described from Rio Tiquie, a tributary of the Rio Uaupes, upper Rio Negro system, Amazon basin, Brazil. The new species is distinguished from its congeners by the presence of thickened skin forming folds that cover the basal portion of the six anteriormost branched anal-fin rays and its interradial membrane. Also, the anteriormost six anal-fin rays are considerably thicker than remaining rays of the fin. Comparisons to Knodus tiquiensis with its congeners are presented based on an examination of type material of all species currently included in the genus.
