Novas especies e subspecies de aves do Brasil Central

Abstract

This article presents a description of a new subspecies of bird from Central Brazil, named *Knipolegus aterrimus franciscanus*, made by E. Snethlage in 1928. The morphological characteristics of the male and female are described in detail, highlighting differences in plumage coloration, markings on the wings, tail, and regions of the chest and abdomen. The male is characterized by uniform black plumage with a white band on the wings, while the female has brown and olive tones, with varied spots and streaks. The study contributes to the taxonomic identification and expansion of knowledge about Brazilian avifauna, especially the species and subspecies present in Central Brazil.
