Type locality of Priocharax britzi, Amazonas, Canutama, small lake approximately 400 m from the rio Ipixuna, after bridge crossing this river, on the right side of the Transamazônica Road (BR–230) going from Humaitá to Lábrea, rio Ipixuna drainage, upper Purus basin. Known only from its type locality in a marginal lake approximately 400 m from the rio Ipixuna, a tributary of the rio Purus (Ref. 124594).

Status of threat: This species was found in a single location, an isolated small lake near the road, where the environmental conditions seem degraded, with depauperate riparian vegetation and silted substrate. Efforts to find specimens in the nearby rio Ipixuna and other close locations were not successful. The type locality is near a protected area (Floresta Nacional de Balata-Tufari), which was not sampled. Future studies should investigate the possibility that the species occur in other localities within the protected area and along portions of the rio Ipixuna that may connect to the lake during the wet season. There are no known imminent threats that would put the species at risk of extinction, thus, the species should be classified as Least Concern (LC) according to International Union for Conservation of Nature (IUCN) categories and criteria (IUCN Standards and Petitions Subcommittee, 2019) pending further information on its real distribution (Ref. 124594).
