Description de quatre nouvelles espèces de Nématodes Héligmosomes, coparasites de l’intestin d’un Trichys lipura malais : Heligmonella limbooliati n. sp., Cordicauda trichysi n. sp., Cordicauda malayensis n. sp. et Cordicauda magnabursa n. sp.
La faune du Trichys est comparée à celle d'Atherurus africanus, qui héberge huit espèces coparasites, dont l’une appartient au genre Heligmonella et les sept autres au genre Paraheligmonina. D’un point de vue phylétique comme d’un point de vue écologique (abondance relative et répartition des espèces dans l’intestin), les deux faunes paraissent avoir évolué de façon rigoureusement parallèle, à partir d’un seul Nématode de type Heligmonella, l’une en Afrique et l’autre en Asie.
Abstract
Description of four new species of Heligmosome Nematodes parasites of the gut of Trichys lipura :
- —
Heligmonella limbooliati n. sp. has a synlophe of Heligmonella-type and a bursa related to Cordicauda.
- —
Cordicauda trichysi n. sp. is characterized by the relatively small dorsal lobe of the bursa, numerous cuticular ridges and the origin of the 8th rib at the distal third of the dorsal rib.
- —
C. malayensis is closely related to C. trichysi (the female of the two species are morphologically identical but the two species can be separated by the larger dorsal lobe of the bursa and the longer spicula of C. malayensis).
- —
C. magnabursa n. sp. is separated from the other species of the genus by the peculiar morphology of the bursa and the female’s tail, dorsally bent.
The fauna of Trichys is compared to that of Atherurus africanus, which is parasitized by 8 coparasites species : One Heligmonella and seven Paraheligmonina. From a phyletic as well as an ecological point of view (relative abundance and species location in the gut) the two fauna seem to have evolved in a parallel way, one in Africa, one in Asia, from a single Heligmonella type Nematode, after the host’s partition.
