| Abstract | |
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 (AU) | |
