Glyptothorax ngapang sp. nov., G. granulus sp. nov. and G. chindwinica sp. nov. are described from Chindwin basin of the state. Characteristic differences in the new species include: G. ngapang sp. nov. in its well tuberculated skin and slender caudal peduncle; G. granulus sp. nov. in having granulated skin and thoracic adhesive apparatus width 78.9-85.0% its length; and G. chindwinica sp. nov. in having large head, depth at nape 55.8-56.7% HL, teeth on upper jaw as broad patch, lateral extent of lower jaw tooth band more than that of upper, and thoracic adhesive apparatus with a shallow pit in the centre. G. manipurensis is differentiated from G. striatus and its status and synonymy with G. sinense is discussed. A key to identification of species of the genus of the state is given. © ZOO.
