Gastrointestinal helminths found in the three freshwater turtles (Erymnochelys madagascariensis, Pelomedusa subrufa and Pelusios castanoides) from Ankarafantsika National Park, Madagascar
Abstract We conducted a survey of the presence, prevalence and diversity of gastrointestinal helminths in faecal samples and stomach contents of three turtle species, — Erymnochelys madagascariensis (Chelonia: Podocnemididae), Pelomedusa subrufa and Pelusios castanoides (Chelonia: Pelomedusidae), — from several localities in Madagascar. Four nematode species were detected: Atractis chabaudi, Camallanus chelonius, Falcaustra pelusios, and Spiroxys sp. E. madagascariensis, with all four species, had the greatest helminth diversity. A. chabaudi was the community’s core species, whereas Spiroxys sp. was a satellite species. Only two species (A. chabaudi and Spiroxys sp.) were found in P. subruf…
A new species of the genus Spiroxys (Nematoda: Gnathostomatidae) from Madagascan pleurodiran turtles (Pelomedusidae)
AbstractSpiroxys ankarafantsika, sp. nov. is described from Madagascar in two species of freshwater turtles, Pelusios castanoides and Pelomedusa subrufa. Spiroxys ankarafantsika differs from other species of the genus in having pseudolabial teeth only on the median lobes and no other cuticular prominences, a smooth cuticular collar, deirides as cervical minute spine-like projections, and a gubernaculum without tubes. This is the first record of a nominal species of the genus Spiroxys from the Ethiopian region.
