Taxonomy and systematics
Nava's wren was originally treated as a subspecies of Hylorchilus sumichrasti, which at that time was called slender-billed wren. After the split, the now-monotypic H. sumichrasti was renamed Sumichrast's wren. Nava's wren is also monotypic.[3]

Nava's wren is 16 cm (6.3 in) long; a female weighed 29.3 g (1.03 oz). The adults have a rich brown crown and upperparts and a tawny face. Their throat and upper chest are whitish that transitions to pale gray on the lower chest and gray-brown at the vent. The lower chest has faint scalloping and the flanks are sooty brown.[3]
