Distribution in the Americas

Tachira Antpitta is known only from four specimens collected along a 5 km stretch of the upper Río Chiquita in southwestern Táchira, Venezuela, and sight records from the same region in June 2016. The full extent of its geographic distribution, historical or present, is unknown; until June 2016, this species had not been reported at all since the original series was collected in 1955-1956 (Collar et al. 1992). The type locality is very close to the border with Colombia, and so this species is expected to occur (or, to have occurred) in the Andes of northeastern Colombia.

The known elevational distribution of Tachira Antpitta is 1800-2100 m (Collar et al. 1992).

Distribution outside the Americas

Confined to the Americas.

Habitat

There is no detailed information available on the habitat of Tachira Antpitta, but it reportedly occupies "the mossy undergrowth of high, dense cloud forest" (Meyer de Schauensee and Phelps 1978).

Tachira Antpitta may be an elevational replacement for Scaled Antpitta (Grallaria guatimalensis); Hilty (2003) noted that the elevational range of Scaled Antpitta in Táchira is only 350-1250 m, compared to 1800-2100 m for Tachira Antpitta.
