Abstract

Scutellonema naveenum sp. n. and S. erectum sp. n. are described from Tamil Nadu, South India. S. naveenum n. sp. is close to S. magniphasmum Sher, 1963 but differs from it in having smaller body size, a more conical head, rounded stylet knobs, absence of cephalids and epiptygma and the characteristic tapering tail having a round terminus. S. erectum sp. n. is the only species with almost straight body, but otherwise close to S. bradys (Steiner & Lellew, 1933) Andrassy, 1958 and can be distinguished from the latter by the presence of fewer number of lip and tail annules, six longitudinal striations on the basal annule of the lip, presence of epiptygma and the absence of vaginal glands and intestine not overlapping the rectum.
