Systematics, Evolution, and Biogeography of the South American Ovenbird Genus Cinclodes
Abstract Phylogenetic relationships within the genus Cinclodes, a group of South American furnariids, were studied using complete sequences of the mitochondrial genes COII and ND3. The 13 species of Cinclodes formed a monophyletic group consisting of three major lineages: (1) the southeastern Brazil...

Abstract Phylogenetic relationships within the genus Cinclodes, a group of South American furnariids, were studied using complete sequences of the mitochondrial genes COII and ND3. The 13 species of Cinclodes formed a monophyletic group consisting of three major lineages: (1) the southeastern Brazilian isolate C. pabsti, which was sister to the rest of the genus; (2) a clade of five primarily Patagonian or central Argentine highlands species; and (3) a clade of seven primarily north-central Andean or Pacific species. Biogeographic structure in the Patagonian-Andean taxa was consistent with the deep Patagonian and north-central Andean division previously noted in the similarly distributed genus Muscisaxicola.
