Teramulus waterloti previously was listed as Lower Risk, least concern. Improved information since then has resulted in the species being uplisted to Endangered.
The reported range of this species extends from the Ifasy River southwards to the Anjingo River. Prior to the mid 1990s this species had not been recorded from collections in decades. It is very patchily distributed over this region (extent of occurrence (EOO) and area of occupancy (AOO) are < 5,000 km² and < 500 km², respectively). While the Anjingo subpopulations have to deal with both habitat degradation as well as exotic competitors and predators, the more northerly subpopulations currently do not. Despite the apparent lack of immediate threats to the subpopulations from basins to the north of the Anjingo River, the restricted EOO and number of known locations for this species, combined with the high degree of habitat degradation in the region, justifies its classification as Endangered.
