The IUCN conservation status of Potamonautes lividus is "VU" or vulnerable. The species faces a high risk of endangerment in the medium term due to residential development and commercial development of its habitat. Humans damming and modification of their freshwater wetlands, bogs, marshes and peatlands (mires) habitats also contribute to their declining.[1]
