ABSTRACT-A new species of oxyuridean nematodes, Neyraplectana fatehpurensis n.sp. (Oxyuridae: Cosmocercinae) has been collected from small intestine of bull frog, Rana tigrina (Anura: Dicroglossidae) in North India during one year (2008)(2009)) uninterrupted investigation and substantiated by the application of polythetic divisive classificatory system. Sums of 257 bull frogs (male 159; female 98) were examined and 239 specimens, Neyraplectana sp. (male 97; female 142) recovered during parasitological investigation. The numerical validation of newer nematodes N. fatehpurensis n.sp. were based on the morphotaxometry of 33 specimens (male 12; female 21). The worms were typically characterized by paired equal spicules, absence of a gubernaculum and plectane, 5 pairs of preanal, 2 pairs adanal and 10-11 pairs post anal papillae, sub-equatorial vulva and in utero embryonated eggs.
