Identification & Behavior: ~12 cm (4.7 in). The male Dot-winged Antwren is jet black with large dots on the wing covers, which form wing bars. The female is variable. All forms have black upperparts and dotted white wing bars. The underparts vary from all chestnut (intercedens and albicauda), to all chestnut with black throat (quixensis), to chestnut only on the breast (nigriventris). Both sexes have a graduated tail with feathers broadly tipped with white. It forages often in pairs at forest edges and second growth. The male is similar to a male White-flanked Antwren but is distinguished by a black plumage and longer tail broadly tipped with white. The combination of a chestnut belly and tail broadly tipped with white is unique. It does not enter the forest interior.

Status: The Dot-winged Antwren is uncommon and widespread in Amazonia where it is known to range up to 1400 m along the east slope of the Andes. It also occurs in Co, Ec, Br, and Bo.
