Typical Antbirds (Thamnophilidae) - HBW 8
White-flanked Antwren (Myrmotherula axillaris)
French: Myrmidon à flancs blancs
German: Weißflanken-Ameisenschlüpfer
Spanish: Hormiguerito Flanquialbo
Other common names: Black Antwren
Taxonomy: Myrmothera axillaris Vieillot, 1817, Guiana = French Guiana.
According to genetic studies, may be most closely related to M. longipennis and M. menetriesii.

Substantial geographical differences in vocalizations strongly suggest that present species should be split into several distinct species, but further work required. Otherwise, morphological distinctions between races heterozyga and fresnayana unclear. Distributions of races given below are tentative, based primarily on previous published statements. Six subspecies recognized.
