Ca. Xiphinematobacter
The Xiphinema americanum-group is a large species complex containing more than 50 nematode species. They are economically important because they are vectors of nepoviruses. The species differentiation of X. americanum-group is problematic because the species share similar morphological characters. In the present study we collected nematode samples from different locations in the USA, Italy and Russia. Six valid species, X. americanum s. str., X. brevicolle, X. californicum, X. pachtaicum, X. riv
