ABSTRACT
A new nematode, the type of a new genus and a new species Laurostrongylus hoineffae, parasitic in the cricetid rodent Gymnuromys roberti in Madagascar, is described. The species belongs to the Graphiidinae subfamily of Trichostrongylidae but some features point to its affinity to certain Libyostrongylinae, especially to two monospecific genera endemic in Madagascar Pararhabdonema and Cnizostrongylus. This ensemble of relict species seems thus to support the concept of a common ancestor for the Libyostrongylinae and Graphidiinae. The two subfamilies were supposed to originate in the Ethipian region. The presence of the three generain Madagascar could either indicate their Madagascan origin or, more likely, a continental origin with an insular niche allowing the preservation of the species
