Unknown to Honduras.

Probably closely related to Merida Wren (Cistothorus meridae) and Apolinar's Wren (Cistothorus apolinari). Taxonomy complex. Subspecies form three geographical groups: "stellaris group" (North America south to Panama), "aequatorialis group" (north-western South America, from Colombia east to Guyana and south to Bolivia) and "nominate group" (southern South America, from northern Argentina and south-eastern Brazil south to Tierra del Fuego). Wide disparities in vocalizations suggest that these groups likely to represent three distinct species; also, the two Neotropical groups possibly worthy of further subdivision.

Proposed subspecies boliviae (from Santa Cruz, in Bolivia) considered indistinguishable from minimus.

The following 20 subspecies are recognised:

• stellaris (Latham, 1790)   -  Breeds from southern Canada (eastern Saskatchewan, central Manitoba, southern Ontario and southern Quebec) southern in USA to northern Kentucky, eastern Pennsylvania and New York. Non-breeding winters from eastern USA (Virginia) south through coastal states to Texas and north-eastern Mexico. Considered by some authors to be a distinct species, Sedge Wren (Cistothorus stellaris).
