Abstract
A new intergeneric hybrid manakin is characterized using morphological characters and mitochondrial and nuclear DNA sequences. Many morphological traits suggest the bird is intermediate between Ilicura militaris and Chiroxiphia caudata. Sequences of the maternally inherited mitochondrial ND2 gene demonstrate the female parent to be Chiroxiphia caudata, and the nuclear beta-fibrinogen intron 5 sequences can not eliminate Chiroxiphia and Ilicura as parents. Therefore, DNA sequence data lead to the conclusion that Ilicura is the male parent of this unusual bird. This study is important because it highlights the significance of using multiple character systems in diagnosing unusual bird specimens. Resumen Um novo híbrido intergenérico foi caracterizado utilizando caracteres morfológicos e seqüências de DNA nuclear e mitocondrial. Vários caracteres morfológicos sugerem que a ave é um intermediário entre Ilicura militaris e Chiroxiphia caudata. Seqüências do gene mitocondrial ND2 herdados via materna demonstram que a progenitora feminina foi uma Chiroxiphia caudata, e seqüências nucleares do intron 5 do beta-fibrinogênio não eliminaram Chiroxiphia e Ilicura como potenciais pais. Logo, os dados de seqüência de DNA levam à conclusão de que Ilicura é o progenitor masculino desta ave pouco comum. Este estudo é importante porque demonstra a significância de utilizar sistemas de múltiplos caracteres na diagnose de espécimes pouco comuns de aves.Keywords
