Description de deux nouvelles espèces du genre Orientostrongylus Durette-Desset, 1971 (Nématode, Héligmosome) chez un Tupaïné et un Petauristiné de Malaisie
Description of two new species of the genus Orientostrongylus Durette-Desset, 1971 (Nematoda, Heligmosomidae) from a Tupaïnae and a Petauristinae in Malaysia

— Orientostrongylus dendrogali n, sp., parasite de Dendrogale melanura (Tupaiiné), proche de O. brevispicularis (Singh, 1962), parasite de Rattus norvegicus en Inde, s’en distingue par la naissance des côtes externo-dorsales à la racine de la côte dorsale et la division de cette dernière dans son tiers antérieur.
— Orientostrongylus krishnansamyi n. sp., parasite d’Iomys horsfieldi (Petauristiné),. proche de O. tenorai Durette-Desset, 1971, parasite de Muridés orientaux, s’en distingue par des spicules à pointe simple et un nombre plus élevé d’arêtes cuticulaires.
La présence d’un Orientostrongylus chez un Tupaiidé, animal relique, nous paraît un élément important pour confirmer la place de ce genre à la base de la seconde branche-évolutive de la lignée Heligmonella.
Abstract
— Orientostrongylus dendrogali n. sp., parasite of Dendrogale melanura (Tupaïnae) is closely related to O. brevispicularis (Singh, 1962) parasite of Rattus norvegicus in India. It can be separated from it by the externodorsal ribs which originate at the proximal end of the dorsal rib and by the division of that in its anterior third.
— Orientostrongylus krishnansamyi n. sp. parasite of Iomys horsfieldi (Petauristinae) is closely related to O. tenorai Durette-Desset, 1971, parasite of oriental Muridae. It can be differentiated from it by the spicules with a simple tip and by more numerous cuticular ridges.
The presence of an Orientostrongylus in a Tupaïdae, a relict animal, seems to be an important argument to confirm the status of this genus which is situated to the basis of the second evolution branch of the line Heligmonella.
