Eremaeoidea

Eremaeus cordiformis, from Seniczak et al. (2013).

Belongs within: Holonota.
Contains: Eueremaeus.

The Eremaeoidea are a group of oribatid mites characterised by the presence in nymphs of an apodemato-acetabular tracheal system. The largest family within the Eremaeoidea is the Eremaeidae, members of of which often exhibit anal neotrichy with up to nine pairs of anal setae (Norton & Behan-Pelletier 2009). The genus Proteremaeus is exceptional in only having two pairs of anal setae, together with three pairs of adanal setae. Members of the European genus Tricheremaeus also have a higher number of setae on the notogaster than other species (more than eleven pairs), with the setae being particularly long.

Characters (from Norton & Behan-Pelletier 2009): Adult prodorsum usually with costulae. Genal notch absent. Dorsophragmata and pleurophragmata absent. Pedotecta I–II present; discidium and circumpedal carina absent. Notogastral setation 7–11 pairs, or neotrichous. Notogastral cerotegument usually with large tubercles (globules). Palpal eupathidium acm separate from recumbent solenidion. Axillary saccule of the subcapitulum occasionally present. Epimere II with 1–3 pairs of setae. Anal and/or adanal neotrichy present or absent. Tarsi I–IV ofen with porose areas present ventrally; tarsus I with 2–3 solenidia; legs IV may be modified for jumping. Larva unideficient. Nymphs with platytracheae or brachytracheae; eupheredermous; opisthonotal setation quadrideficient, quinquedeficient, or neotrichous. Preanal organ hollowed as caecum.
