Belongs within: Desmonomata.

Crotonia is a mostly Southern Hemisphere genus of relatively large mites found arboreally and among leaf litter. Colloff (1990) referred to six species groups within the genus of which the C. caudalis, C. nukuhivae and C. unguifera groups are restricted to New Zealand and islands of the Pacific whereas the other groups are more widespread on ex-Gondwanan continents.

Characters (from Balogh & Balogh 1992): Bothridial sensillus present. Notogastral margins converging posteriad, posterior extremity nearly pointed with ciliate apophyses. Epimeral setal formula 3-1-3-3. Genital and anal plates of macropyline type, large, occupying entire ventral side posterior to epimeres; seven or eight pairs of genital setae; two pairs of aggenital setae; three pairs of anal setae; three pairs of adanal setae. Legs tridactyl.
