A putative fossil sejid mite (Parasitiformes: Mesostigmata) in Baltic amber re-identified as an anystine (Acariformes: Prostigmata)

Jason A. Dunlop, David E. Walter & Jenő Kontschán
The Acari (mites) is currently interpreted to consist of two superorders. In contrast to the relatively rich history of the mite superorder Acariformes, fossils of the Parasitiformes are extremely rare. This is especially true of the most diverse order, Mesostigmata, with only nine families recorded, including four named species, having been described so far. As part of a wider effort to clarify the diversity of Baltic amber Mesostigmata the historically oldest fossil, Sejus bdelloides Koch...

Fabio Akashi Hernandes
A new feather mite species, Psittophagus hollandicus n. sp. (Acariformes: Pterolichidae), is described from the cockatiel Nymphicus hollandicus (Kerr, 1792) (Psittaciformes: Cacatuidae) kept in captivity in Brazil.

Eriophyoid mites from ferns: description of a new Leipothrix Keifer species (Eriophyidae: Phyllocoptinae) from the Arasbaran forests (Iran) and a key to the world species

Parisa Lotfollahi & Enrico de Lillo
A survey of eriophyoid mites on ferns was carried out in the Arasbaran forests, East Azerbaijan province, Iran. A new species of the genus Leipothrix Keifer (Eriophyidae: Phyllocoptinae: Phyllocoptini) was collected on Polypodium vulgare L. (Polypodiaceae), named as L. pterisfolii, described and illustrated. It is the first record of a mite of the tribe Phyllocoptini on a Polypodiaceae plant. This mite species was found also on a plant of the family Cystopteridaceae, namely Gymnocarpium dryopteris...

Life table of the red spider mite Tetranychus bastosi (Acari: Tetranychidae) on different host plants

R. Pereira de Lima, Marcello M. Bezerra, Gilberto J. de Moraes & Imeuda Furtado
Tetranychus bastosi Tuttle, Baker and Sales was described from Ceará state, northeastern Brazil. It has so far been reported from 25 plant species, among which cassava (Manihot esculenta Crants), common bean (Phaseolus vulgaris L.) and papaya (Carica papaya L). Although there is no information about its impact on crop yield, high population levels have been observed on some crops, leading to suppose that damage might occur in some occasions. In this study, fertility life table...

On the taxonomic status of the water mite genus Spongibates Wainstein, 1978 (Acari, Hydrachnidia, Hygrobatidae)

Petr V. Tuzovskij & Harry Smit
The identity of the water mite genus Spongibates Wainstein, 1978 has been examined. After examination of the holotype, we conclude that Wainstein described an aberrant Hygrobates species, very likely H. nigromaculatus. Therefore, Spongibates should be considered a junior synonym of Hygrobates.

Molecular phylogenetic relationships of halacarid mites suggest the reevaluation of traditional subfamily classification

Hiroko Meguro, Masahiro A. Iwasa, Koichi Goka & Hiroshi Abé
Molecular phylogenetic relationships were examined for marine mites in the subfamilies Halacarinae, Copidognathinae, Rhombognathinae and Halixodinae from the aquatic mite family Halacaridae by using nuclear 18S and 28S ribosomal RNA gene sequences. The analysis revealed incongruences between the clustering obtained in the phylogenetic trees and the current morphological classification in the subfamilies Halacarinae and Rhombognathinae (based on 18S sequences) and in the Rhombognathinae (based on both 28S and combined 18S and 28S sequences). By contrast,...

New records, a completed list and identification key of mites (Acari) associated with the stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae)

Jenő Kontschán & Sándor Hornok
The stable fly, Stomoxys calcitrans (L.) is a blood-sucking muscid fly species, with a worldwide distribution and high veterinary-medical importance. In this study, four mite species were collected from stable flies in Hungary. One mite species (Trichotrombidium muscarum (Riley, 1878)) from the family Microtrombidiidae was parasitic on the flies, collected in high numbers from their bodies. The other three species were found in small numbers on the flies, which they use only for transportation. The...

Typhloseiulus arzakanicus (Arutunjan), found for first time in Italy,...

A predator-prey system: Phytoseiulus persimilis (Acari: Phytoseiidae) and Tetranychus urticae (Acari: Tetranychidae): worldwide occurrence datasets

Alain Migeon, Marie-Stéphane Tixier, Maria Navajas, Vassilis D. Litskas & Menelaos C. Stavrinides
The predator-prey system Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae) and Tetranychus urticae (Koch) (Acari: Tetranychidae) represents the most studied and the most known system among the Acari. Because of the agronomical importance of the two mite species, a wealth of modelling studies investigated the interactions of the two species at the individual level. However, regional or global level works on this system are lacking, which is impeding the investigation of climate change effects on biological control...
