The waltonelline Ochoterenella esslingeri n. sp., a filarial parasite of the anuran Bokermannohyla luctuosa in Minas Gerais, Brazil is described. Several characters distinguish this new species from the 15 species presently included in the genus: the cuticular ornamentation of the female that is restricted to the posterior region of the body, the irregular arrangement of the small, rounded bosses, the postoesophageal vulva, the short glandular oesophagus, the size and shape of the microfilariae, the long left spicule and high spicular ratio. Irregularly arranged, tiny, rounded bosses are common in the monotypic genus Paraochoterenella from an Indonesian ranid, which is not well defined but likely valid. In the Neotropical Realm, the type hosts of the species of Ochoterenella are Hylidae (O. esslingeri n. sp.), Leptodactylidae (two species) and the remaining 13 species were described from the giant toad Rhinella marina (Bufonidae).
Résumé
Description d’une filaire Waltonellinae Ochoterenella esslingeri n. sp., parasite d’un anoure, Bokermannohyla luctuosa, au Minas Gerais, Brésil. La nouvelle espèce est distincte des 15 autres du genre par l’ornementation cuticulaire de la femelle limitée à la région postérieure du corps et faite de petites bosses rondes distribuées irrégulièrement, la vulve postoesophagienne, l’oesophage glandulaire court, la taille et la forme de la microfilaire, le spicule gauche long et le rapport spiculaire élevé. Les bosses petites, rondes et distribuées irrégulièrement se retrouvent chez le genre monotypique Paraochoterenella, un parasite de ranidé indonésien, dont la définition n’est pas claire, mais qui est vraisemblablement un genre valable. En région néotropicale, les hôtes types des espèces d’Ochoterenella sont des Hylidae (O. esslingeri n. sp.), Leptodactylidae (deux espèces) et Bufonidae, précisément le crapaud géant Rhinella marina (les 13 autres espèces).
