Oribatellidae

Dorsal (left) and ventral view of Oribatella (Fenestrobates) capucinus, from Balogh & Balogh (1992).

Belongs within: Circumdehiscentiae.
Contains: Oribatella (Oribatella).

The Oribatellidae are a cosmopolitan family of oribatid mites characterised by the present of large, fused lamellae on the prodorsum, and the retention by nymphs of scalps (exuvia of previous instars) that are nevertheless held away from the body by setae. The family is cosmopolitan in distribution, but most diverse in warm temperate regions of the Holarctic (Norton & Behan-Pelletier 2009). Most species have the prodorsal lamellae fused or at least in contact medially, though they remain distinct in the Argentinian Cuspidozetes armatus (Balogh & Balogh 1992 vol. 1).

Characters (from Norton & Behan-Pelletier 2009): Prodorsum with large, broad lamellae, fused at base of lamellar cusps; tutorium usually rectangular, dentate distally. Genal notch present. Dorsophragmata and pleurophragmata present. Chelicerae chelate-dentate; palpal eupathidium acm attached to solenidion; subcapitular mentum without tectum. Axillary saccule of subcapitulum present. Discidium and custodium present; postanal porose area present or absent. Pedotectum I large, extending to base of bothridium; pedotectum II present. Notogastral setation 10-15 pairs; pteromorphs present, without hinge. Octotaxic system developed as four pairs of porose areas. Genital setation six pairs. Bothridium without internal, ringlike thickenings, cup shaped, or with medial dens. Genu IV shorter than tibia IV; tibia IV with solenidion. Immatures unideficient; nymphs apopheredermous, hysterosoma with lateral carina, without plicae, microsclerites or macrosclerites. Humeral organ present. Seta d lost on tibiae and genua when respective solenidion is present.
