Nematodes of high altitudes in India. VIII. Pungentus duvatus N. sp. with a key to species of the genus Putzgetztus (Nematoda: Dorylaimida)

Abstract

Pungentus clauatus n. sp. from the Simla hills (India) is distinct from al1 other species of the genus in the possession of an oesophago-intestinal disc and a short, clavate tail. This new species is close to P. siluestris (De Man, 1912) Coomans & Geraert, 1962 but differs in having narrower amphidial apertures, smaller odontophore and different tail shape. Alr ey to the valid species and a lisotf species inquirendae of the genus Pungentus are provided. Two nomenclatorial rearrangements are proposed : P. siluestris Eroshenlro, 1976 becomes a junior synonym of P. granosus Eroshenlro, 1976, (notet hat the specific name siluestris was preoccupied by P. siluestris (De Man, 1912) Coomans & Geraert, 1962) ; P. medianus Eroshenko, 1976 is considered a junior synonym of P. purnilus Andrassy, 1963.
