Belongs within: Psoroptidia. The Pterolichidae are a group of astigmatine mites found living in the feather vanes of a range of bird orders. Females either have the legs inserted laterally or have anterior tarsi less than twice the length of the tibiae, and lack ad setae. A little piece of feathery paradise Published 13 June… Continue reading Pterolichidae


Belongs within: Acaroidea.Contains: Acarus, Rhizoglyphinae. The Acaridae are a diverse group of often generalised astigmatan mites. Many species are insect associates with a phoretic hypopus (deutonymph) stage in the life cycle (Philips 1990). Members of the basal subfamily Acarinae appear to be vertebrate nidicoles (i.e. living in vertebrate nesting structures such as nests, burrows or… Continue reading Acaridae


Belongs within: Psoroptidia.Contains: Alloptidae, Avenzoariidae, Pteronyssidae, Proctophyllodidae, Sarcoptoidea, Pyroglyphidae, Turbinoptidae, Xolalgidae, Analgidae. The Analgoidea are a group of astigmatan mites usually found as parasites or paraphages of birds, more rarely as nidicoles or in synanthropic habitats (OConnor 2009). They are closely related to the mammal-associated Sarcoptoidea and may possibly be paraphyletic to the latter group. A… Continue reading Analgoidea


Belongs within: Holonota.Contains: Histiostomatidae, Canestrinioidea, Hemisarcoptoidea, Acaroidea, Hypoderatidae, Psoroptidia, Glycyphagidae. The Astigmatina are a group of soft-bodied mites lacking respiratory tracheae (Philips 1990). Many have rapid life cycles, and may be significant scavengers of decomposing matter. Most astigmatines (excluding the vertebrate-associated Psoroptidia) have a modified non-feeding deutonymph (hypopus) stage in the life cycle that is… Continue reading Astigmatina


Belongs within: Astigmatina.Contains: Acaridae. The Acaroidea are a group of mites commonly associated with nests of vertebrates or Hymenoptera though members of the family Acaridae have become more diverse in habits. Females of the Acaroidea have a strongly folded pseudovipositor that they use in egg deposition (OConnor 2009). Species of Lardoglyphus are best known as… Continue reading Acaroidea


Belongs within: Rhizoglyphinae.Contains: Schwiebea. The Rhizoglyphini are a group of acarid mites characterised by the lack of seta aa on the first tarsus. Klimov (1998) divided this lineage into two tribes, Rhizoglyphini and Thyreophagini, based on the appearance of seta ba on the first two tarsi (stout and spine-like in ‘Rhizoglyphini’, weak and stick-like in… Continue reading Rhizoglyphini


Belongs within: Acaridae.Contains: Rhizoglyphini. The Rhizoglyphinae are an ecologically diverse group of astigmatan mites, commonly associated with moist temporary habitats. With the exceptions of the basal genera Acotyledon and Viedebanttia, many rhizoglyphines exhibit male polymorphism with major males developing modifications for fighting. The genus Sancassania includes species found in fungal fruiting bodies, root crops and… Continue reading Rhizoglyphinae


Belongs within: Astigmatina. The Hypoderatidae are a group of astigmatine mites found in vertebrate nests, many of which are only known from parasitic deutonymphs (OConnor 2009). Characters (from OConnor 2009): Adult with body cuticle usually smooth or with scale-like ornamentation; palpi reflexed inward; propodosoma with lamellar (le) setae absent; discrete coxal apodemes III–IV present, projecting… Continue reading Hypoderatidae


Belongs within: Astigmatina.Contains: Histiostoma. The Histiostomatidae are a group of astigmatan mites found on wet substrates, most commonly feeding by filtering organic particles and microorganisms from the water film. Most species are associated with isolated or ephemeral habitats and some may have the shortest development times of any astigmatan mites, going through their entire life… Continue reading Histiostomatidae


Belongs within: Astigmatina. The Canestrinioidea are a group of astigmatine mites that live as paraphages on beetles (OConnor 2009). Characters (from OConnor 2009): Adults with gnathosoma normally developed, palpi and chelicerae occasionally elongated; chelicerae typically chelate, rarely elongate and edentate. Idiosoma with cuticle smooth, striate, reticulate, scaly, or sometimes well-sclerotised; sejugal furrow inconspicuous; chaetome complete… Continue reading Canestrinioidea
