Subspecies
Thryothorus maculipectus (Sibley and Monroe 1990, 1993) was provisionally split into Thryothorus maculipectus, Thryothorus colombianus, Thryothorus paucimaculatus and Thryothorus sclateri by Stotz et al. (1996). Thryothorus sclateri has been recognised as a distinct species following SACC (2005), but colombianus and paucimaculatus have been lumped with Spot-breasted Wren (Pheugopedius maculipectus) following SACC (2005).
Sometimes treated as conspecific with Rufous-breasted Wren (Pheugopedius rutilus) and Maranon Wren (Pheugopedius sclateri), despite great differences in plumage and vocalizations. In past, suggested as possibly being conspecific with Happy Wren (Pheugopedius felix).
Proposed subspecies varians (Pacific slope from Chiapas, in southern Mexico, south to El Salvador) and petersi (northern Honduras south to northern Costa Rica) are considered indistinguishable from umbrinus.
The following 6 subspecies are recognised:
microstictus Griscom, 1930 - North-eastern Mexico (south-eastern Nuevo León and central Tamaulipas south to eastern San Luis Potosí and northern Veracruz).
maculipectus (Lafresnaye, 1845) - Eastern Mexico (Veracruz south to Puebla and northern Oaxaca).
umbrinus (Ridgway, 1887) - Southern Mexico (north-eastern Oaxaca, Tabasco, Chiapas), southern Belize, Guatemala (except Petén), El Salvador, northern and southern Honduras, and Caribbean slope of Nicaragua and northern Costa Rica.
petersi Griscom, 1930 - Northern Honduras to northern Costa Rica.
varians ? - Southern Mexico (Pacific slope of Chiapas), Guatemala and El Salvador.
