Based on a model of future deforestation in the Amazon basin, it is suspected that the population of this species will decline by 25-30% over the next three generations, and it has therefore been uplisted to Near Threatened.

14-15cm, 28-34g. Large bare periorbital patch, ear coverts, breast sides, breast and throat all white. Top of head black in male, chestnut brown in female. Upperparts olive-brown, female has buff-edged black tips to coverts, mantle, and rest of underparts while the male is plain, and has grey underparts. Similar spp. Bicoloured Antbird Gymnopithys leucapsis has a similar pattern of white throat and breast, and the nominate has white extending onto face sides. This does not extend across the whole of the ear coverts or the breast sides, both of which are black. The periorbital patch is also smaller than in R. hoffmansi. Voice Loudsong begins with a long slurred whistle followed by 6-7 shorter whistles becoming downslurred and ending with a few lower pitched burry notes. Calls are similar to R. gymnops; a harsh "chirr" and an abrupt "chip".
A significant proportion of the range of the species now lies within Protected Areas (A. Lees in litt. 2011), including the Pacaás Novos National Park in Rondônia.
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). Campaign against proposed changes to the Brazilian Forest Code that would lead to a decrease in the width of the areas of riverine forest protected as Permanent Preservation Areas (APPs), which function as vital corridors in fragmented landscapes.
