Phenopelopidae

Belongs within: Poronoticae.
Contains: Eupelops.

The Phenopelopidae are a family of oribatid mites with movable pteromorphae and usually dilated setae on the notogaster. They are most known primarily from leaf litter in temperate regions with some species also found at higher altitudes in the tropics (Norton & Behan-Pelletier 2009).

Members of the genera Nesopelops, Peloptulus and Eupelops have slender, peloptoid chelicerae and an acuminate rostrum. Propelops retains non-peloptoid chelicerae and a rounded rostrum but is related to the remaining phenopelopids by characters such as the close association of the small porose areas on the notogaster with individual notogastral setae, and the presence in nymphs of a ventral tuberculate area anterior to the genital opening (Norton & Behan-Pelletier 1986). Peloptulus differs from Nesopelops and Eupelops in having very small setiform interlamellar setae; in the other two genera, the interlamellar setae are long and leaf-shaped. Nesopelops has the quadrangle formed by the setal pairs lm and lp broader than it is long, and has two pairs of adanal setae (Balogh & Balogh 1992).

Characters (from Balogh & Balogh 1992): Prodorsum with tutorium, lamellae and translamellae. Ten pairs of notogastral setae, setae usually dilated. Pteromorphae well developed, more or less movable. Octotaxic system developed as four pairs of areae porosae. Six pairs of genital setae, one pair of aggenital setae, two pairs of anal setae, two or three pairs of adanal setae. Legs monodactyle or tridactyle.
