Bestimmung

The long-winged antwren is 9 to 10.5 cm (3.5 to 4.1 in) long and weighs 8 to 10 g (0.28 to 0.35 oz). It is a smallish bird with a short tail. Adult males of the nominate subspecies M. l. longipennis have dark gray upperparts with a hidden white patch between the shoulders and white tips on the scapulars. Their wings are dark gray with white-tipped black coverts. Their tail is gray with white tips on the feathers. Their throat and upper breast are black; the rest of their underparts are a paler gray than the upperparts. Adult females have an ochraceous face, olive-brown upperparts, and dark grayish brown tail and wings. Their wing coverts and flight feathers have deep cinnamon edges. Their throat and breast are light buff. The rest of their underparts are mostly white with a gray tinge; their flanks are light gray with an olive tinge. Subadult males are like adult females with some light gray on the lower back and rump.<p>Males of the other subspecies of the long-winged antwren all have white tips on their facial feathers, and more black on the breast and slightly paler though variable underparts than the nominate. Females differ from the nominate and each other thus:

Taxonomie

The long-winged antwren was described by the Austrian ornithologist August von Pelzeln in 1868 and given its current binomial name Myrmotherula longipennis.<p>The long-winged antwren has these six subspecies:<p>Some authors have suggested that some subspecies deserve to be treated as separate species, and M. l. garbei was so treated by one early 20th century author. The long-winged antwren and the band-tailed antwren (M. urosticta) form a superspecies.
