Abstract

D. mukundai sp. nov. and D. rayi sp. nov. from the intestine of R. tirapi from Namdhapa Biosphere Reserve, Arunachal Pradesh, India, are described. D. mukundai is differentiated from all species of the genus by a bifurcated axostyle. It most closely resembles D. parva but differs in having a larger body and in that the axostyle is distinct throughout its length. The latter characteristic also differentiates it from D. nobilis and D. leidyi. The new species is distinguished from D. rugosa and D. exilis in body shape. D. rayi is characterized by the regular arrangment of the prominent ridges on the body surface, which is also found in D. leidyi, D. rugosa and D. gracilis; it differs from these species in its body shape and from D. leidyi also in its shorter posterior flagellum and in the distinctive posterior protrusion of the axostyle. This is the first record of a member of Dinenympha from India.
