Comments on the Xiphinema americanum group
A paper by Luc et al. (1998) synonymizes several species within the Xiphinema americanum group, and excludes some species from it. The authors conclude that there are 34 valid species and 3 species inquirendae, and a full list of these species is given. They also define the characteristics of the group.
EPPO note: this does not change the EPPO view that members of this group are only of quarantine significance because of their ability to transmit quarantine viruses and that the only members which have this ability are populations from North America of Xiphinema americanum sensu stricto, X. californicum, X. bricolense and X. rivesi.
