Xenospingus is a genus of finch-like tanager. It contains a single species, the Slender-billed Finch (Xenospingus concolor). The slender billed finch is restricted to southwest Peru and northern Chile, and inhabits mainly riverine vegetation along coastal valleys It has been considered endangered due to loss of habitat. Riparian thickets that were common are under pressure from logging by farm owners. Some information has indicated that it has adaptated to threats using olive trees areas and other artificial habitats successfully.
