IUCN Red List

This distribution range of this species was thought to include the east coast rivers between Mangoro and Mananara du Sud, Madagascar. However, recent research suggests that G. brevibarbis is only known from the holotype, which was presumably collected within the upper to middle reaches of the Mananjary river drainage in the southeastern highlands of Madagascar (Ng and Sparks 2005). Anchariids are difficult to collect as they are active at night, and far more survey work needs to be done in the region of the type locality to determine range and population size (J. Sparks pers. obs.). In light of this new evidence, the assessment for this species is Data Deficient. Prior assumptions regarding range and population size are no longer valid (IUCN 2016).
