Genus Oribatodes Banks, 1895

Type species: Oribatodes mirabilis Banks, 1895

Generic diagnosis. Adult. With character states of Cepheusidae (e.g., Sitnikova 1975; Bernini & Bernini 1990; Weigmann 2006; Norton & Behan-Pelletier 2009). Body size: Medium-sized to large (length about 400–1000). Integument: Body and legs covered by layer of gel-like cerotegument, sometimes with bacillar, granulate and tuberculate inclusions. Prodorsum usually foveolate; notogaster without heavy sculpturing, but with simple foveolae which often forming reticulate or polygonate ornamentation; anogenital region with ridges, depressions and foveolae. Prodorsum: Rostrum rounded or narrowly triangular. Lamella broad, distinctly not reaching rostrum, with short cusp having lateral tooth. Translamella absent. Prolamella present or absent. Tutorium present, ridge-like. Rostral and lamellar setae medium-sized/long, setiform, with or without flagellate tip; interlamellar seta medium-sized/long, setiform/robust; bothridial seta with long stalk and slightly developed, barbed and/or shortly ciliate head; exobothridial seta absent. Interbothridial and postbothridial tubercles absent. Dorsosejugal porose area, dorsophragma and pleurophragma absent. Notogaster: Anterior notogastral margin well developed, distinctly convex medially, rarely straight. Humeral region with short tubercle-like process. Pteromorph and octotaxic system absent. Ten pairs of notogastral setae (centrodorsal part of notogaster without setae) short/medium-sized/long, mostly setiform, but sometimes some setae bacilliform or slightly phylliform. Gnathosoma . Subcapitulum diarthric. All subcapitular setae setiform. Palp with setation: 0-2-1-3-9(+ω); solenidion bacilliform, coupled with eupathidium mediodistally. Axillary saccule absent. Chelicera chelate-dentate, with two setae. Epimeral and lateral podosomal regions: Epimeral setal formula: 3-1-3-3; epimeral setae comparatively short, setiform. Pedotectum I represented by large scale, pedotectum II represented by small scale. Humeral porose area not observed. Discidium and circumpedal carina present. Anogenital region: Six pairs of genital, one pair of aggenital, two pairs of anal, and three pairs of adanal setae comparatively short, setiform. Marginal porose area absent. Adanal lyrifissure distanced from anal plate. Legs: All legs monodactylous. Porose areas present on all femora and on trochanters III, IV.
