  ## Taxonomy and systematics
  
  The Santa Marta wren has often been treated a subspecies of mountain wren (Troglodytes solstitialis). The South American Classification Committee of the American Ornithological Society (SACC/AOS) considers those two, ochraceous wren (T. achraceus), rufous-browed wren (T. rufociliatus), and tepui wren (T. rufulus) to be a superspecies.
  
  The Santa Marta wren is monotypic.
  
  ## Description
  
  The Santa Marta wren is 11.5 cm (4.5 in) long. The adult's crown and upperparts are rufous brown with blackish barring on the lower back. The tail is brown and also has dark barring. It has a buffy supercilium and eyering. Its chin is pale buff that darkens to buffy brown on the throat and chest. Its flanks are buffy white with dark brown bars and the vent area white with blackish bars. The juvenile is similar but has dark tips on the feathers of the back and underparts.
