Taxonomia
Abstract in Portuguese
O gênero Pulsatrix Kaup, 1848 pertence à família Strigidae, que abriga as corujas, mochos e caburés. Pulsatrix possui distribuição Neotropical e compreende 9 táxons, caracterizados pelo grande porte, cabeça de cor escura e arredondada, sem “orelhas” e um supercílio ou “óculos” claro, contrastante em formato de “X” e característico do grupo. Apenas três espécies são reconhecidas neste gênero: Pulsatrix koeniswaldiana é monotípica e restrita à Mata Atlântica; Pulsatrix melanota é limitada aos Andes tropicais, com duas subespécies, e Pulsatrix perspicillata é amplamente distribuída nas Américas Central e Sul, e possui uma grande variação morfológica ao longo de sua distribuição, atualmente representada por seis subespécies. Uma revisão taxonômica para o gênero nunca foi proposta e os limites de distribuição entre os táxons são divergentes e imprecisos na literatura. Foram utilizados um total de 475 espécimes depositados nas principais coleções do mundo. A variação morfológica foi extensamente estudada e foi possível determinar apenas três espécies monotípicas no gênero: P. perspicillata (Latham, 1790), P. melanota (Tschudi, 1844) e P. koeniswaldiana (Bertoni & Bertoni, 1901), e a distribuição de cada um destes táxons foi atualizada

Taxonomy
Abstract in English
The genus Pulsatrix Kaup 1848 belongs to the Family Strigidae. The family is represented by owls. Pulsatrix has a neotropical distribution and consists of nine taxa, characterized by their large size, dark-coloured head, without “ear tufs” and a clear and contrasting eyebrow in the facial disc. Among the three currently accepted species, Pulsatrix koeniswaldiana is monotypic and restricted of rainforest. Pulsatrix melanota is limited to the tropical Andes, with two subspecies, and Pulsatrix perspicillata is widely istributed throughout Central and South America. It possesses a high degree of morphological variation throughout its distribution and is represented by six subspecies. However, a taxonomic revision for the genus has never been undertaken and the distribution limits of the taxa differ widely in the literature. We studied 475 specimens housed in the main ornithological in the world. The morphological variation was extensively studied and we were able to determine only three monotypical species: P. perspicillata (Latham, 1790), P. melanota (Tschudi, 1844) and P. koeniswaldiana (Bertoni & Bertoni, 1901), and the distribution of each taxa was updated
