The Trombellidae are a group of large, often colourful mites found in forest litter whose larvae are parasitic on insects (Walter et al. 2009).

Characters (from Walter et al. 2009): Adults with idionotum entirely surrounded by peripheral sclerotised band, or bearing 2-16 circular depressions with peripheral sclerotised bands, or with idionotal borne on raised papillae but lacking basal sclerites. Larvae with idionotum bearing unpaired prodorsal sclerite but lacking scutellum, setae c1 located on paired platelets; coxal plates smooth; urstigmata present between coxal plates I-II; femur I bearing 5-6 branched setae; femora II-III bearing multiple solenidia θ; pretarsus with empodium.
