Eranina amacayacu Botero and Noriega, new species from Amazonas, Colombia, is described and illustrated. The genus Erana was proposed by Bates (1886) for a single species, Erana cincticornis Bates, 1886, from Amazonas, Brazil. Many other species were described in the genus during the following decades until the revision of the South American species by Martins and Galileo (1989). In this work, the authors redescribed the genus, described four new species, and transferred two more to Erana. Monné (2005) proposed Eranina as a nomem novum because Erana Bates, 1886 is a homonym of Erana Gray, 1840 (Aves: Passeriformes). Martins and Galileo (2014) revised, a second time, the South American species and proposed a key for them. At that moment, the genus was composed of 36 species, 18 from South America and 18 from Mexico and Central America.Ayear later, Mehl et al. (2015) described a new species from Paraguay, Eranina tomentilla Mehl. Currently, the genus is composed of 37 species with distribution from Mexico to Argentina (Monné 2017).
