A new Corydoras species is described from the Igarapé Castanha, a tributary of rio Tiquié, upper rio Negro basin, Brazil. The new species belongs to a basal clade of long-snouted Corydoras (Lineage 1 or Corydoras acutus species-group) and occurs syntopically with a co-mimic species, Corydoras tukano, which is considerably more abundant. Based on the pectoral-spine morphology, it is herein suggested that Corydoras species belonging to the Lineage 1 are Batesian mimics of congeners belonging to Lineages 6 to 9, rather than Müllerian co-mimics as recently hypothesized.
