Adult males of the nominate subspecies have a white supercilium that extends down the neck, along the side of the breast, and widens on the flanks. Their crown and upperparts are dark grayish brown with white edges on the scapulars and a hidden white patch between them. Their wings are brownish black with white tips on the coverts. Their tail is black with white feather tips that increase in size from the central to the outer feathers. Voice: The southern white-fringed antwren has several vocalizations. The "monotone song" is a "single soft chup note repeated...as many as 50 notes". Another is an "extremely variable complex note...churet or chuweet. A third is "kip-chrup liquid phrase of two well-spaced notes". There are some minor geographic variations. Both sexes sing, typically when hidden in foliage, and mostly in the morning.
