title: A New Ataloderinae (Nematoda: Heteroderidae), Thecavermiculatus gracililancea n. gen., n. sp.
abstract: Thecavermiculatus gracililancea n. gen., n . sp. is described from the roots of Festuca myuros L. ("rattail fescue") a range grass in Monterey County, California. Thecavermiculatus females have a slight terminal prominence on which are located the vulva and anus, while its closest relatives, Atalodera and Sherodera, have a large terminal prominence. Furthermore, in T. gracililancea the hatched second-stage juveniles are retained in the female body while Atalodera and Sherodera females retain embryonated eggs.
