A revision of the genusCarnoya Gilson, 1898 (Nematoda: Rhigonematidae) with descriptions of four new species

  • Martin L. Adamson


The type specimen ofCarnoya dubia Dollfus, 1952 is redescribed and four new species ofCarnoya are described.C. paradubia n. sp. fromRhinocricus nattereri varians from São Sebastião island, Brazil, most similar toC. dubia, is distinguished from the latter by having twice as many rows of cervical spines, by the absence of interlabial formations and by the position of the phasmids in the male.C. dollfusi n.sp. from the same host and locality asC. paradubia and most similar toC. pyramboia Artigas, 1926 is distinguished by the disposition of caudal papillae in the male and the form of the cervical spines in the female.C. martiniquensis n.sp. fromAnadenobolus politus from Martinique andC. venezuelensis n.sp. fromRhinocricus flavocinctus from Colony Tovar, Venezuela differ from all otherCarnoya spp. by having broad, well-developed lips and three cuticular projections at the base of the buccal cavity in the male. InC. martiniquensis the six inner papillae in the male are located on separate swellings, two on the inside edge of each lip whereas inC. venezuelensis there is only one swelling per lip and each bears a pair of inner papillae. Females of the two species differ in that the vulva is ventral inC. martiniquensis but subventral inC. venezuelensis. An emended diagnosis of the genus and a key to the known species is given. ac]19830221
