Abstract
A new nasute termite Ceylonitermes nivedita sp. nov. (Isoptera: Termitidae) is described from the tropical rainforests of Manipur, India. Both the soldier and worker castes of the species are described. The workers are strongly dimorphic and no such dimorphism is reported hitherto among the 3 known species of Ceylonitermes. A revised dichotomous key to identify all the 4 known species of the genus is also provided. The proposed new species is a minor pest of bamboo.
Key words: Ceylonitermes, India, Nasutitermitinae, key
