The genus Cistothorus was circumscribed by the German ornithologist Jean Cabanis in 1850.[1][2][a] The type species is the sedge wren (Cistothorus stellaris).[3][4]


The genus contains five species:[2]

  • Sedge wren, short-billed marsh wren, Cistothorus stellaris – northern Mexico, United States and southern Canada
  • Mérida wren, Cistothorus meridae – Venezuelan Andes
  • Apolinar's wren, Cistothorus apolinari – Colombian Andes
  • Grass wren, Cistothorus platensis – central and South America
  • Marsh wren, long-billed marsh wren, Cistothorus palustris – Mexico, United States and southern Canada

The sedge wren and the grass wren were formerly treated as conspecific. They were split based on the results of a molecular phylogenetic study published in 2014.[5]
