Chestnut-bellied Mountain-Tanager (Dubusia castaneoventris) is found only at very high altitudes, inhabiting elfin forests and edges, as well as patches of forest near treeline. It is usually encountered in pairs or individually in the midstory, foraging primarily on insects. Once considered the only species in the genus Delothraupis, this species was moved to the genus Dubusia when molecular phylogenetic analyses recovered it sister to Buff-breasted Mountain-Tanager (Dubusia taeniata). Due to the remote habitats where it is found, very little information is known about this species. Despite being difficult to study and having an unknown population status, Chestnut-bellied Mountain-Tanager has not been placed on any threatened species lists. The common name in Spanish is Tangara Ventricastaña (Hilty 2011, de Juana et al. 2012). The genus name Dubusia honors the Belgian politician and patron of the sciences, Bernard Dubus de Ghisignies (Jobling 2010). The English name is a direct translation of the specific epithet, which derives from the Latin words castaneus meaning "chestnut-colored", and ventris meaning "belly" (Jobling 2010).
