Order Isolaimiida Inglis, 1983
Andrassy (2009) asserts that the root of Isolaimium is
Isloaimi. The root is de3termined by removing the Latinized ending "um"
from Isolaimium. Then appropriate ennings are added to the root to designate
different taxonomic levels. Consequently, the correct names of the Order, Sub-order,
Superfamily and Family are, respectively, Isolaimiida, Isolaimiina.
Isolaimioidea and Isolaimiidae and not Isolaimida, Isolaimina. Isolaimoidea and
Isolaimidae as used by several authors.
