title: Two new rhabditida species (Nematoda: Rhabditidae) parasites of Cyclocephala signaticollis (Coleoptera: Scarabaeidae) in Argentina.
abstract: Two different Rhabditida species (Nematoda: Rhabditidae) Parasitorhabditis platidontus n. sp. and Cruznema campestris n. sp. are described and illustrated from the larvae of Cyclocephala signaticollis (Coleoptera: Scarabaeidae) from Buenos Aires province, Argentina. Parasitorhabditis platidontus n. sp. is characterized by having 4 odontoplates in the stoma and the vulva is at 80% of the length of the body.
