“…E. dujardini is synonymized with E. entomelas. Schad et al (1960) reported two species of Entomelas from A. fragilis (E. entomelas and E. dujardini), however, Baker (1980) accepted E. dujardini is synonym of E. entomelas, in this situation only E. entomelas distributing in Turkey. The genera Paraentomelas, Hexadontophorus and Kurilonema were synonymized with Entomelas.…”

“…E. entomelas is a commonly observed nematode species for A. fragilis in Europe (Yamaguti, 1961). Baker (1980) redescribed the genus Entomelas specimens from A. fragilis and Ophisaurus apodus. He emended the generic diagnosis of Entomelas.…”

“…The following morphological and biological characters indicate a close relationship between the present specimens and the Rhabdiasidae Railliet, 1916(see Chitwood & Chitwood, 1950Chabaud, 1974;Baker, 1980;Anderson & Bain, 1982): equatorial vulva; vagina transverse and without well-developed sphincters; amphidelphic; reflexed ovaries; oesophagus of adult undivided, short, thick and with bulb but rhabditoid in hatching larva; no parasitic male; egg has thin shell and contains larva; free-living phase present; infective larva occurs within its exuviae and has short oesophagus, one-third of body length; and tail extremity conical, without lappet.…”

Chabirenia cayennensis n. g., n. sp. (Nematoda: Rhabdiasidae) is described from the teiid lizard Ameiva ameiva. A total of 139 worms were recovered, all females, from the mucous glands of the buccal cavity. The worm has a free-living phase in a homogonic life-cycle. Infective larvae are enclosed in a sheath with chequered ornamentation and composed of two exuviae. The new genus is distinct from the five known genera of the family, Pneumonema Johnston, 1916, Acanthorhabdias Pereira, 1927, Entomelas Travassos, 1930, Rhabdias Stiles and Hassall, 1905 and Neoentomelas Hasagawa, 1989, in the following characters: helical habitus, longitudinal cuticular crests, very tiny buccal cavity without thick walls and three oesophageal onchia. Several characters of this new rhabdiasid suggest the Strongylida.

The genus Entomelas Travassos, 1930 currently includes nine species of rhabdiasid nematodes, eight of them parasitic in lizards and only one, Entomelas sylvestris Baker, 1982, parasitic in amphibians. Entomelas sylvestris was originally described from the Forest Rain Frog Breviceps sylvestris FitzSimons in South Africa and was not reported since. It was placed in the genus Entomelas without any specific arguments for this taxonomic decision, presumably mainly based on details of the buccal capsule morphology. We have found this species in the same host in Limpopo province, South Africa. Molecular phylogenetic analysis based on the newly-obtained sequence of complete ITS region and partial nuclear large ribosomal subunit (28S) gene of E. sylvestris and previously published sequences of a variety of other rhabdiasid taxa, has convincingly demonstrated that this species does not belong in Entomelas. Instead, it clustered together with the members of Rhabdias Stiles & Hassall, 1905 from amphibian hosts. Therefore, we transfer E. sylvestris into Rhabdias as Rhabdias sylvestris (Baker, 1982) n. comb. In our analysis E. sylvestris appears, albeit with weak support, as a basal/sister taxon to the rest of Rhabdias spp. which explains to some extent the differences in the buccal capsule morphology between this species and other Rhabdias spp.
