The Anisitsiellidae are a diverse group of freshwater mites of questionable monophyly, larvae of which are (where known) parasites of nematocerous Diptera (Walter et al. 2009). They may be divided between the subfamily Anisitsiellinae, in which the dorsum and venter are each largely covered by single large plates, and Nilotoniinae, in which the venter is soft or with separated plates and the dorsum bears small sclerites or two larger plates.
Characters (from Walter et al. 2009): Adults with claws either present or absent on legs IV; when claws present, then lateral eyes usually located on platelets associated with ventral shield; venter with suture lines between coxal plates II-III complete; genital field with movable genital flaps flanking gonopore; genital acetabula conspicuous, lying free in gonopore.
