Rarity Status
Currently this species is not classified as a rarity in this country OR information has not been updated.
Population
Estimated population is unknown (2010).
Status VU
Habitat destruction and degradation due to accelerating deforestation as land is cleared for cattle ranching and soy production, facilitated by expansion of the road network, is the main threat.
For more information see BirdLife International Species Factsheet.
Habits
Sometimes associates with mixed species flocks.
Voice
Song is a loud, countable series of whistled notes, falling in pitch.

Subspecies
Relationships of genus not clearly established. Preliminary molecular evidence suggests affiliation with Thamnophilus, and morphological characteristics have connected it with Thamnomanes. Species was formerly treated as conspecific with geographically remote Plumbeous Antvireo (Dysithamnus plumbeus), and incorrectly transferred to Thamnomanes. Subspecies tucuyensis distinctive, and widely separated geographically from nominate. Vocal and molecular studies may indicate it is a separate species.
The following 2 subspecies are recognised:
tucuyensis Hartert, 1894 - Northern Venezuela (coastal mountains from Falcón and Lara to Monagas).
leucostictus Sclater, 1858 - Eastern slope of Andes from central Colombia (southern from Meta) south to extreme northern Peru (northern Amazonas, Cajamarca).
Similar Species
The male could be mistaken for a male Plain Antvireo (Dysithamnus mentalis), but is larger and uniformly dark above and below. Male Slaty Antwren (Myrmotherula schisticolor) is also smaller.
