Typical Antbirds (Thamnophilidae) - HBW 8
Dusky-throated Antshrike (Thamnomanes ardesiacus)
French: Batara ardoisé
German: Nördlicher Schwarzkehlwürgerling
Spanish: Batará Gorgioscuro
Other common names: Grey-throated Antshrike/Antvireo
Taxonomy: Dysithamnus ardesiacus P. L. Sclater and Salvin, 1868, Río Napo, Ecuador.
Relationships to other genera unclear. Species currently placed in genus appear to be related on basis of morphology and behaviour, although their nest architecture is somewhat variable. Present species has sometimes been placed in genus Dysithamnus. Forms a superspecies with T. saturninus and has been treated as conspecific; taxonomic study of populations needed. Races appear to intergrade; specimens in N part of range of nominate approach obidensis in extent of black on male throat, and region in E Colombia that is said to separate races is poorly known ornithologically..

Relationships to other genera unclear. Species currently placed in genus appear to be related on basis of morphology and behaviour, although their nest architecture is somewhat variable. Present species has sometimes been placed in genus Dysithamnus. Forms a superspecies with T. saturninus and has been treated as conspecific; taxonomic study of populations needed. Races appear to intergrade; specimens in N part of range of nominate approach obidensis in extent of black on male throat, and region in E Colombia that is said to separate races is poorly known ornithologically; further work required. Two subspecies recognized.
