The nematode, Daubaylia helicophilus sp. n., is described from the snail, Gyraulus spirillus, originating from Taiwan. This species is distinguished from previously described members of the genus by the shape of the tail in both sexes, as well as the overall length and size and shape of the spicules and gubernaculum, respectively.
Populations of infected snails have been maintained for a period of years and ingestion of the gravid female nematode seems to be at least one mode of infection. D. helicophilus will also infect other snails, experimentally, including the schistosome-bearing snail, Biomphalaria glabrata.
Résumé
Cette espèce se distingue des autres espèces voisines du genre par la forme de la queue des deux sexes, mais aussi par la longueur totale du corps et la forme et la longueur des spicules et du gubernaculum.
Des populations de mollusques contaminés ont été maintenues pendant plusieurs années et au moins l’un des modes d’infestation semble être l’ingestion de la femelle gravide du nématode. Expérimentalement D. helicophilus peut aussi infester d’autres planorbes dont Biomphalaria glabrata, agent vecteur du schistosome.
