Based on a model of future deforestation in the Amazon basin, and its dependence on primary forest and susceptibility to fragmentation, it is suspected that the population of this species will decline rapidly over the next three generations, and it has therefore been uplisted to Vulnerable.

Thamnomanes leucostictus Stotz et al. (1996)
12-13 cm. Small, short-tailed, dimorphic antbird. Male dark grey, blackest on breast, with white tips and edges to wing-coverts. Female reddish brown above, with grey underparts streaked white. No streaking on lower belly, Reddish brown vent. Similar spp. The male could be mistaken for a male Plain Antvireo D. mentalis, but is larger and uniformly dark above and below. Male Slaty Antwren Myrmotherula schisticolor is also smaller. Voice Song is a loud, countable series of whistled notes, falling in pitch.
The primary threat to this species is accelerating deforestation in the Amazon basin as land is cleared for cattle ranching and soy production, facilitated by expansion of the road network (Soares-Filho et al. 2006, Bird et al. 2011). It appears to be restricted to little-disturbed primary forest, and as such is likely to be particularly susceptible to fragmentation and edge effects (del Hoyo et al. 2003, A. Lees in litt. 2011).
Conservation Actions Underway
None is known.
Conservation Actions ProposedExpand the protected area network to effectively protect IBAs. Effectively resource and manage existing and new protected areas, utilising emerging opportunities to finance protected area management with the joint aims of reducing carbon emissions and maximizing biodiversity conservation. Conservation on private lands, through expanding market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture, is also essential (Soares-Filho et al. 2006).
