Subspecies
No subspecies.
Although traditionally placed in genus Thryomanes, and sometimes in Thryothorus, it is generally agreed among ornithologists familiar with this species that it exhibits features typical of present genus. Recent work using mitochondrial DNA supports its placement in present genus, close to House Wren (Troglodytes aedon) and Southern House Wren (Troglodytes musculus). In the past, considered by some to form a superspecies with Bewick's Wren (Thryomanes bewickii), with suggestion that they might even be conspecific. Species name insularis commonly used prior to 1951, when sissonii was shown to have priority. Proposal for treatment of latter as a nomen oblitum has generally been ignored, and since 1951 sissonii has been used almost universally.
