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] :
