ABSTRACT

Cephalobium magdalensis n.sp. (Rhabditida Diplogasteridae) found in Magdalena, Buenos Aires, and Cruznema lincolnensis n. sp (Rhabditida Rhabditidae) found in Lincoln, Buenos Aires, parasitizing the cricket Gryllodes laplatae (Orthoptera Gryllidae) are described and illustrated. C. magdalensis n. sp. is characterized by having the excretory pore between the pseudobulb and the basal bulb and seven pairs of postanal papillae in the male. C. lincolnensis n.sp. can be distinguished by having meanly two pairs of preanal papillae, one pair of adanal papillae and six pairs of postanal papillae in the male.
