Abstract
Sisorid catfishes of the genus Glyptothorax of Manipur, India is revised. 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.
