          Abstract

          Description of Hypocristata tercera n. sp. (Heligmonellidae, Nippostrongylinae) a parasite of the small intestine of Sigmodon hispidus (Rodent, Sigmodontinae) from Venezuela. Two other species were described in the genus, both from Colombia and parasitic in Sigmodontinae. H. thomosomysi Durette-Desset, 1970, a parasite of Thomasomys sp. has about the same number of cuticular ridges at mid-body but differs by ridges having chitinoid struts, a caudal bursa pattern of type 2-2-1 (vs 1-3-1). H. anguillula Durette-Desset, 1970, a parasite of Sigmodontomys alfari (= Nectomys alfari) has the same caudal bursa pattern (type 1-3-1) but differs by the presence of ridges at mid-body in both sexes (absent at that level in H. tercera) and by ridges having chitinoid struts in female. This is the first report of the genus Hypocristata Durette-Desset, 1971 in Venezuela and in the genus Sigmodon (Sigmodontinae).
