Neomisticius Siddiqi, 1986
Type species of the genus: Neomisticius. rhizomorphoides (Ruhm, 1955) Siddiqi, 1986
Synonyms: None.
The genus Neomisticius is sometimes classified in the Anguinidae and sometimes in the Sphaerulariidae. However, recent molecular data indicates that the genus should be in the Anguinidae (Subbotin and Chzihov, 2019).

Males:
Isolated from the bark of trees; insect associates.
Note that the number of species of insect-associated nematode has been estimated to be between 4000 and 500,000 (Giblin-Davis et al., 2013; Kanzaki et al., 2022).
Neomisticius spp. are probably fungal feeding with phoretic relationships with beetles. Neomisticius platypi has been cultured on fungus (Kanzaki et al., 2022).
The type species of the genus, N. rhizomorphoides, was originally described as a phoretic associate of Xyleborus dryographus in Germany (R�hm, 1955). Since then, it has been re-isolated from galleries of X. dispar and Xyleborinus saxeseni in the branches of cherry trees in California, USA (Subbotin & Chizhov, 2019)
