Sterling’s toothed toad (Oreolalax sterlingae) was first described in 2013 and is the one member of the genus identified from Vietnam. The species is considered endemic to Vietnam’s highest mountain, Mount Fansipan, in northern Vietnam at elevations exceeding 2700 m a.s.l. Sterling’s toothed toad is one among simply two Critically Endangered amphibians at the moment identified from Vietnam and has an “Extent of Incidence” (EOO) of simply eight km2. One of many beneficial conservation actions for the species is to find out its distribution. Over a interval of three years our workforce surveyed different websites on Mount Fansipan and excessive elevation websites within the Hoang Lien Vary and we encountered Sterling’s toothed toad larvae at comparatively low elevation on Mount Pu Ta Leng within the newly created Bat Xat Nature Reserve, 20 km northeast of the kind locality. This tremendously will increase each the elevation vary of the species (from 2900 m a.s.l to 2345–3108 m a.s.l) and the EOO (from eight km2 to 639 km2). We advise that Sterling’s toothed toad is reassessed as Endangered in accordance with the IUCN Pink Record of Threatened Species classes and standards B1ab(iii).
