Oripodoidea

Neotrichozetes spinulosus spinulosus, photographed by S. E. Thorpe.

Belongs within: Circumdehiscentiae.
Contains: Hemileiidae, Parakalummidae, Scheloribatidae, Oripodidae, Haplozetidae, Mochlozetidae, Zetomotrichidae, Caloppiidae, Oribatulidae.

The Oripodoidea are a diverse group of mostly mycophagous oribatid mites. Where known, immatures of this superfamily usually possess excentrosclerites in association with the setae, leading to this group sometimes being referred to as the Excentrosclerosae (Norton & Behan-Pelletier 2009). In adults, the octotaxic system on the notogaster may be presented as either areae porosae or sacculi; Drymobates silvicola is distinctive in possessing both, with anterior sacculi and posterior areae porosae (Balogh & Balogh 1992a). In members of Mochlozetidae and Haplozetidae, the octotaxic system may be multiplied, with up to fifty pairs of areae porosae in some Mochlozetidae (Norton & Behan-Pelletier 2009).

The habitat preferences of oripodoids are varied. Symbioribates papuensis is known from the elytra of weevils found in cryptogamic plants (Norton & Behan-Pelletier 2009).

Characters (from Norton & Behan-Pelletier 2009): Prodorsum with lamellae well deveoped, reduced to a narrow carina, or absent; tutorum and translamella present or absent. Bothridium often covered by anterior margin of notogaster. Genal notch absent. Prodorsum and notogaster separate or fused. Dorsophragmata and pleurophragmata present. Chelicerae chelate-dentate or pelopsiform; palpal eupathidium acm attached to solenidion; subcapitular mentum without tectum. Axillary saccule of subcapitulum absent. Discidium and custodium present or absent; postanal porose area absent. Pedotectum I small, usually not covering acetabulum I, pedotectum II small or absent. Circumpedal carina present. Notogaster with or without lenticulus, without tectum posteriorly; pteromorphs present or absent, if present, with or without hinge. Notogastral setation 9-15 pairs. Octotaxic system diverse, often with more or fewer than four pairs, rarely absent. Genital setation 1-6 pairs. Genital plates well removed from anal plates and virtually bisecting epimere IV. Usually with porose organs on tibiae and tarsi. Genu IV shorter than tibia IV; tibia IV with solenidion. Immatures apheredermous; unideficient; some or all opisthonotal setae usually with excentrosclerites; humeral organ absent; seta d absent from tibiae and genua when respective solenidion is present.
