Going Asexual: A Survey of Mites of the Genus (Acari: Acaridae) Revealing a Large Number of New Parthenogenetic Species in the Holarctic Region.

Mites of the genus (Acari: Acaridae) are distributed worldwide; they inhabit concealed habitats and include several beneficial and economically important species. However, species identification is difficult because many species are poorly described or delimited and their phoretic stages are unknown or uncorrelated. Furthermore, is interesting because it includes entirely asexual (parthenogenetic) species.

An interesting sexually dimorphic species, Chamobates callipygis Pavlichenko, 1991 (Acari, Oribatida, Chamobatidae), with remarks on sexual dimorphism in Ceratozetoidea.

Based on materials from the leaf litter of a mixed forest in Crimea, a new diagnosis for the sexually dimorphic species, Chamobates callipygis Pavlichenko, 1991, is presented to accommodate its previously unreported females. This is the only species in Chamobatidae showing a distinct sexual dimorphism, which is expressed by the posterior porose region on the notogaster, such that males only have a large protuberance on the posterior part of notogaster bearing a pair of fused porose areas A3, and a densely striated region behind them. The specific function of this structure is not yet known, but the sexual dimorphism is presumably involved in pheromonal communication facilitating sperm transfer.

A transitional fossil mite (Astigmata: Levantoglyphidae fam. n.) from the early Cretaceous suggests gradual evolution of phoresy-related metamorphosis.

Metamorphosis is a key innovation allowing the same species to inhabit different environments and accomplish different functions, leading to evolutionary success in many animal groups. Astigmata is a megadiverse lineage of mites that expanded into a great number of habitats via associations with invertebrate and vertebrate hosts (human associates include stored food mites, house dust mites, and scabies). The evolutionary success of Astigmata is linked to phoresy-related metamorphosis, namely the origin of the heteromorphic deutonymph, which is highly specialized for phoresy (dispersal on hosts).

Phoretic mite communities associated with bark beetles in the maritime and stone pine forests of Setúbal, Portugal.

The phoretic mite communities of prominent bark beetle pests associated with pine stands of southern Portugal were sampled to determine whether they vary across bark beetle species and stand type. Bark beetles were sampled for mites from two primary (aggressive) bark beetle species (Ips sexdentatus and Orthotomicus erosus) and the most common secondary species (Hylurgus ligniperda) in maritime pine (Pinus pinaster) and stone pine (Pinus pinea) in the Setúbal province of Portugal. Twelve mite species, spanning diverse ecological roles, are found associated with these bark beetle systems.
