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...

Revision of the genus Pseudobryobia McGregor, 1950 (Acari, Tetranychidae)

Tea Arabuli, Ivana Marić & Philippe Auger
The species of the tetranychid mite genus Pseudobryobia are revised mainly based on data published in the literature. Following a survey of the classification history of the genus, emphasizing the changes that occurred in the morphological characters used in its definition, we briefly discuss their relative importance for the genus delimitation. As a result, we provide amended diagnoses for the genera Pseudobryobia and Bryobia and transfer 7 species from Pseudobryobia to Bryobia. Species belonging to...

A new mite species of the genus Neottialges (Acariformes: Hypoderatidae) from the black stork Ciconia nigra (Ciconiiformes: Ciconiidae) in Portugal

Sergey V. Mironov & David W.R. Ramilo
Deutonymphs of hypoderatid mites (Astigmata: Hypoderatidae) are subcutaneous parasites of various groups of birds and some rodents. A new hypoderatid mite species, Neottialges (Caloenectes) ciconiae n. sp., is described from the black stork, Ciconia nigra (Ciconiiformes: Ciconiidae), in Portugal. The new species is most similar to but differs from N. (C.) distinctus Fain and Lawrence, 1986 in having smaller prodorsal and hysteronotal shields not encompassing bases of setae si, se, cp, c2, e2 and h1,...

The true identity of Pascal’s mite and the diachronic use of ciron

Henri M. André
The identity of Blaise Pascal’s mite is examined. Linguistics, morphology, habitat and size reveal that Pascal’s mite is not Acarus siro L., as usually thought, but Sarcoptes scabiei (L.). The diachronic use of the popular term ciron is explored from a number of different perspectives. In everyday language and in Pascal’s time, the term used to designate A. siro L. was mite (used singly, in English and French) and not ciron, a word restricted to...

A new species of Arrenurus (Acari, Parasitengona, Hydrachnidia) found in the crop of a Yellow-billed Teal Anas flavirostris in Bolivia

Antonio G. Valdecasas
New findings of organismal dispersal by other organisms can help explain the distribution of species to remote places. In this work, I describe a male and a female of a new water mite species of the genus Arrenurus that were found in the crop of an Anas flavirostris duck near Cochabamba, Bolivia. Both specimens were complete; however, it is unknown if they were alive and, thus, potentially viable at the time of collection. This study...

First record of Poecilochirus mrciaki Mašán, 1999 (Acari, Parasitidae) and its phoretic carriers in the Iberian peninsula

Marta I. Saloña Bordas & M. Alejandra Perotti
We report for the first time the presence of Poecilochirus mrciaki Mašán, 1999 in the South of Europe, in the Iberian peninsula and on new carrier insects. Mites were collected from carrion insects, during a decomposition experiment carried out in the natural park “Aiako Harria” (Errenteria, Gipuzkoa). Most deutonymphs were found on the body of the necrophagous beetle Necrodes littoralis (Coleoptera, Silphidae). Other species of insects in families Geotrupidae, Staphylinidae (Coleoptera) and Calliphoridae (Diptera) were...

Neottialges (Caloenectes) vulturis (Dubinin, 1956) (Acari: Hypoderatidae) from the Eurasian griffon vulture (Gyps fulvus) in Italy: first record in Europe, redescription and pathological changes in the host

Claudio De Liberato, Adele Magliano, Francesco Tancredi, Claudia Eleni, Mario Posillico & Sergey Mironov
Deutonymphs of the astigmatan mite Neottialges (Caloenectes) vulturis (Dubinin, 1956) comb. n. (Astigmata: Hypoderatidae) were found during the anatomo-histopathological study of a Eurasian griffon vulture, Gyps fulvus, found dead in Central Italy. After skinning, numerous cystic formations were visible in the subcutaneous tissue of the vulture, each containing a parasitic mite. Microscopically, subcutaneous tissue showed large areas of severe granulomatous inflammation. To our knowledge, this is the first record of this poorly known hypoderatid mite...

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.

Paraquanothrus n. gen. from freshwater rock pools in the USA, with new diagnoses of Aquanothrus, Aquanothrinae, and Ameronothridae (Acari, Oribatida)

Roy A. Norton & Elizabeth Franklin
Many taxa of mites inhabit long-lived freshwater environments, but the few known to live in small, ephemeral rock pools (lithotelmata) are brachypyline Oribatida. One of these is in the South African genus Aquanothrus (Ameronothridae). We describe adults and juveniles of two new rock-pool species from the USA and propose the sister-genus Paraquanothrus n. gen. to include them. The type-species, Paraquanothrus grahami n. sp., inhabits shallow weathering-depressions (‘pans’) on barren sandstone in the Colorado Plateau, especially...

Great molecular variation within the species Phytoseius finitimus (Acari: Phytoseiidae): implications for diagnosis decision within the mite family Phytoseiidae

Marie-Stéphane Tixier, Victor Dos Santos Vicente, Martial Douin, Carlo Duso & Serge Kreiter
Molecular markers are increasingly used for species identification and new taxa description. However, rules to determine frontiers between populations and species are not clear depending on taxa considered. For mites, few studies deal with molecular diagnoses, making rules for associated decision difficult. The present study focuses on a species of the predatory mite family Phytoseiidae (Phytoseius finitimus), considered for biological control of mites and small insect pests in fruit orchards and vineyards in the Mediterranean...

First records of Phytoseiidae (Acari: Mesostigmata) from one island of the Comoros archipelago

Serge Kreiter, Rose-My Payet, Jacques Fillâtre & Hamza Abdou Azali
The Comoros Archipelago is constituted of four islands. These islands are located in the North Mozambique Channel in the Indian Ocean, one of the world’s hotspots of biodiversity. Despite this status of hotspot, only one species of Phytoseiidae was known from this Archipelago, from Mayotte: Phytoseius mayottae. No species were recorded from the three other islands. We report in this paper the results of a preliminary survey in Great Comoro or “Grande Comore” Island also...
