| Genus monographed by Allen
in 1955 - 34 species, 22 new species, 12 old or already described. In
1962, A.D. Baker listed 55 species. Sher
listed over 100 species (200 in family and subfamily).
Several related genera are differentiated on the following characters:
Widely distributed - almost any collection will usually contain from one to four species.
Over 100 species of stunt nematodes have been described.
D-rated pests in California.
Generally true ectoparasites on epidermal cells and root hairs, but capable of endoparasitic feeding on some hosts.
