Longidoridae Explained

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.^[1]

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.^[1]
