El género Neotropical Sporophila contiene un grupo de ocho especies conocido coloquialmente como los capuchinos del sur. Dicho grupo muestra una marcada variación fenotipica (principalmente en la coloración y el canto de los machos) que contrasta con la falta de monofilia a nivel de especie y bajos niveles de diferenciación en marcadores genéticos neutros. Este patrón ha sido atribuido al origen reciente del grupo y a la hibridacion e introgresion entre especies. Una revision taxonómica reciente de la única especie politípica, S. bouvreuil (la cuál contenía cuatro subespecies), designó a S. bouvreuil y S. pileata como nuevas especies en base a patrones de coloración y distribución geográfica. En el presente estudio utilizamos secuencias de ...
