Longidoridae (longidorid nematodes) is a family of polyphagous root ectoparasites in the phylum Nematoda (nematodes) with a worldwide distribution.
Taxonomy There are about 720 species divided amongst seven genera in the family, which is further subdivided into subfamilies and tribes.
Subdivision Subfamilies; Longidorinae (480 spp.) Xiphineminae (240 spp.)
Tribes; Subfamily Longidorinae Longidorini Xiphidorini Subfamily Xiphineminae
Genera Subfamily Longidorinae Tribe Longidorini Longidorus (144 spp.) Longidoroides (13 spp.) Paralongidorus (72 spp.) Tribe Xiphidorini Australodorus (1 sp.) Paraxiphidorus (3 spp.) Xiphidorus (8 spp.) Subfamily Xiphineminae Xiphinema (some 240 spp.)
Pathology With the Trichodoridae, the Longidoridae form the two Enoplea nematode families known to be plant parasites, though from different subclasses, and the only virus vectors (particularly nepoviruses) in phylum Nematoda.
