The narrow-billed antwren exhibits sexual dimorphism. The male is dark grey, with a black breast. It has 2 white wing bars and white tips on the outer tail feathers. The female, however, is olive breasted and with brown wings.[2] It has been noted that these birds also look very similar to the silvery-flanked antwren.
