Hyadesia uncinifer, from Lohmann (1907).

Belongs within: Astigmatina.
Contains: Ensliniellinae.

The Hemisarcoptoidea are a diverse group of astigmatine mites found in various arboreal and aquatic habitats, many being inquilines in nests of Hymenoptera (OConnor 2009).

Characters (from OConnor 2009): Adults with gnathosoma normally formed; chelicerae chelate-dentate, or rarely fixed digit reduced. Subcapitulum and palpi normally formed, rarely elongated. Idiosoma with cuticle smooth, mammillate, microtrichous, or occasionally strongly sclerotised. Propodosomatic sclerite shield-like, sometimes elongate, shortened, or occasionally absent. Ocelli sometimes present on propodosoma. Sejugal furrow present or absent. Dorsal chaetome complete except setae le always absent; paraproctal chaetome complete to strongly reduced. Coxisternal skeleton normally developed; chaetome complete or setae g and/or 4b modified or absent in males. Female with oviporus in form of inverted V, epigynal apodeme often present. Male without paranal suckers; often with modified legs or pretarsi I–II; legs IV strongly modified in some male Algophagidae; males polymorphic in some Chaetodactylidae. Mating position parallel. Leg chaetome always lacking a” and usually ft’ from tarsus I, other reductions common. Pretarsal ambulacra well developed, empodial claws normally developed, enlarged, or absent. Deutonymphs with gnathosomatic remnant variously developed or absent. Idiosoma fusiform or round in outline, well sclerotised, typically with strong pattern of striations, occasionally smooth; propodosomatic ocelli often present; sejugal furrow usually present, rarely absent. Coxisternal skeleton usually normally developed, reduced in some Carpoglyphidae; chaetome complete, or with some or all coxal setae reduced to alveolar vestiges. Attachment organ with ancestral complement of suckers and conoidal setae, strongly reduced in regressive forms. Legs normally developed, or legs IV reduced, lacking pretarsus and with very long tarsal setae; tibia-tarsus IV fused in some; chaetome complete except always lacking a” and ft’ from tarsus I; setal reductions common on tarsus IV. Pretarsi with or without membranous ambulacrum; empodial claws normally present, rarely absent.
