Four new species are added to the philopotamid fauna of India. The newly described species under Chimarra Stephens are Chimarra barnardi sp. nov. and C. padami sp. nov. (both from Arunachal Pradesh), C. bidenta sp. nov. from Uttarakhand and C. quadrata sp. nov. from Sikkim. These species are distinguishable from each other as well as from previously known allied species by consistent variation in the structure of inferior appendages, tergite X and the phallic apparatus of males.
