Mesopristes elongatus perviously was listed as Lower Risk, least concern. Improved information since then has resulted in it being uplisted to Vulnerable.
is species remains widely distributed in Madagascar's east coast rivers, between Mahanara and Manarara. Pending major shifts in land use in the basin, this species is assessed as Vulnerable on the basis of its extent of occurrence and area of occupancy being less than 20,000 km² and less than 2,000 km² respectively, and a continuing decline in distribution range due to the impact of deforestation leaving the habitat highly fragmented. The species is rarely collected, despite much recent effort throughout its presumed range, and it is debatable whether it should be upgraded to an assessment status of Endangered. However, data are currently lacking to resolve this question.
