Typical Antbirds (Thamnophilidae)
Undulated Antshrike (Frederickena unduligera) - HBW 8, p. 537
French: Batara ondé
German: Dunkelbrauner Ameisenwürger
Spanish: Batará Ondulado
Taxonomy: Thamnophilus unduliger Pelzeln, 1868, Rio Içanna, north-west Brazil.
Genus presumed related to Thamnophilus on basis of external morphology, especially the strongly hooked bill, but supporting molecular or other evidence unavailable. Considered to form a superspecies with F. viridis. Races defined on basis of female plumages, but racial assignment of specimens often difficult because of extensive individual (though possibly age-related) variation, even among females from same locality; geographical limits of fulva and diversa are based on preliminary vocal analysis; re-examination of taxa required, and molecular and vocal analysis l..

Genus presumed related to Thamnophilus on basis of external morphology, especially the strongly hooked bill, but supporting molecular or other evidence unavailable. Considered to form a superspecies with F. viridis. Races defined on basis of female plumages, but racial assignment of specimens often difficult because of extensive individual (though possibly age-related) variation, even among females from same locality; geographical limits of fulva and diversa are based on preliminary vocal analysis; re-examination of taxa required, and molecular and vocal analysis likely to prove most useful. Four subspecies recognized.
Subspecies and Distribution:
- unduligera (Pelzeln, 1868) - NW Amazonian Brazil on upper R Negro, possibly extending S to N bank of R Solimões.
- fulva J. T. Zimmer, 1944 - SE Colombia (E Cauca, W Caquetá, W Putumayo), E Ecuador and E Peru (N of R Marañón and R Amazon), possibly extending E into Brazil (Amazonas N of R Solimões).
- diversa J. T. Zimmer, 1944 - E Peru (S of R Marañón and R Amazon) and NW Bolivia (S La Paz, extreme S Beni).
- pallida J. T. Zimmer, 1944 - SW Amazonian Brazil (Amazonas S of R Amazon), probably also NC Bolivia (E Pando).
