Based on a model of future deforestation in the Amazon basin, and its dependence on primary forest, 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.

|Range Description:||Myrmoborus lugubris is a polytypic river edge species of central Amazonia, and is fairly common. Subspecies berlepschi occurs Amazonas in extreme south-east Colombia, in Napo in extreme north-east Ecuador, in Loreto in north-east Peru, and in extreme west Amazonian Brazil from Rio Solimões eastwards to Tocantins (Zimmer et al. 2016). The other races are all found in Amazonian Brazil. Subspecies stictopterus ranges along the Rio Negro and nearby Rio Solimões, and is present in Rio Negro State Park's Anavilhanas Archipelago; it is presumably the subspecies found in 2002 in Roraima (Zimmer et al. 2016). Subspecies femininus is restricted to the lower Rio Madeira. The nominate subspecies lugubris is distributed along the Amazon River through Amazonas and Pará, from the junction with Rio Madeira in the west, eastwards as far as Baía do Guajará (del Hoyo et al. 2003, Zimmer et al. 2016).|
