In 1998, Trombidiformes was divided into the Sphaerolichida and the Prostigmata.[1] The group has few synapomorphies by which it can be defined, unlike the other major group of acariform mites, Sarcoptiformes.[1] Its members include medically important mites (such as Demodex, the chiggers, and scrub-itch mites) and many agriculturally important species, including the spider mites (Tetranychidae).[1] The superfamily Eriophyoidea, traditionally considered members of the Trombidiformes, have been found to be basal mites in genomic analyses, sister to the clade containing Sarcoptiformes and Trombidiformes.[2]
The 2004 classification retained the two suborders, comprising around 125 families and more than 22,000 described species.[3]
In the 2011 revised classification, the order now contains 151 families, 2235 genera and 25,821 species, and there were another 10 species with 24 species that present only as fossils.[4] These 151 families were classified into the same two major suborders:[4]
- Sphaerolichida OConnor, 1984: Now contains only two families;
- Prostigmata Kramer, 1877: Still the biggest branch in this taxon, with four infraorders and 40 superfamilies.
