Oribatellidae

Belongs within: Poronoticae.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… Continue reading Oribatellidae
