Typical Antbirds (Thamnophilidae)

Yellow-browed Antbird (Hypocnemis hypoxantha) - HBW 8, p. 645

French: Alapi à sourcils jaunes German: Gelbbrauen-Ameisenschnäpper Spanish: Hormiguero Cejiamarillo

Taxonomy: Hypocnemis hypoxantha P. L. Sclater, 1869, “upper Amazonia”.
Although genus traditionally placed after Myrmoborus, it appears closely related to Drymophila. Present species regarded as sister-species of H. cantator; recent genetic study, however, indicates considerable genetic distance between the two, suggesting that speciation may have occurred several million years ago. Two subspecies recognized.
