Three species of Thai endemic mammal, the Thailand roundleaf bat (Hipposideros halophyllus: Rhinolophidae), the limestone rat (Niviventer hinpoon: Muridae), and the Neil’s rat (Leopoldamys neilli: Muridae), have not been reported from their own type localities for at least 31 years since their first discoveries. The type localities are now being continuously disturbed by human activities, which may result in driving them to the brink of extinction. Intensive surveys were conducted to determine the present existences of these endemic mammals in 7 areas using live trapping and mistnetting techniques. The results reveal the existence of the three endemic mammals. The Thailand roundleaf bat, an insectivorous species, was found in two areas: Khao Samorkhon, Amphoe Tha Wung, Changwat Lop Buri (14o54’38” N, 100o30’02” E), its type locality, and Khao Singto, Amphoe Muang district, Changwat Sa Kaeo (13o54’34” N, 102o03’46” E). The limestone rat was encountered in 2 areas: Khao Dondung, Amphoe Ban Mi, Changwat Lop Buri (15o08’35” N 100o36’44” E), which was the first record of its occurrence outside its known distributional range, and Wat Tham Prathat, Amphoe Muang, Changwat Lop Buri (14o48’15” N 100o49’30” E). Neill’s rat was found living at Wat Tham Prabhothisat, Amphoe Kaenhkoi, Changwat Sara Buri (14o34’31” N 101o08’43” E); its type locality is the same as that of the limestone rat. The results indicated that all endemic mammals occurred in extremely low numbers and had very restricted distributional ranges. Together with the alarming disturbances of anthropogenic factors, they are confronting a high risk of being exterminated locally.
