Sergey G. Ermilov & Leonila Corpuz-Raros
A new species of the genus Hardybodes (Oribatida, Carabodidae) is described from the nest of an unknown species of ants (Formicidae) in soil in Luzon Island, Philippines. Hardybodes minutus n. sp. differs from all species of the genus by the localization of notogastral setae (lm and h2 inserted in the same longitudinal rowdorsocentrally together with da, dm, dp, lp and h1 versus lm and h2 in dorsolateral positions and da, dm, dp, lp and h1...

The Tenuipalpidae (Acari: Trombidiformes) of Israel

Edward A. Ueckermann, Eric Palevsky, Uri Gerson, Eitan Recht & Pieter D. Theron
An annotated list and key to the 26 species of phytophagous false spider mites (Trombidiformes: Tenuipalpidae) known from Israel is provided. About two thirds are exotics, having invaded Israel within the last 35 years. Eight species, namely Brevipalpus californicus, B. lewisi, B. obovatus, B. phoenicis, B. yothersi, Raoiella indica, Tenuipalpus granati and T. punicae are agricultural pests. The others have little economic impact, or are possibly controlled by natural enemies. A key to all the...

Susceptibility to acaricides and detoxifying enzyme activities in the red spider mite, Oligonychus coffeae Nietner (Acari: Tetranychidae)

Somnath Roy, Anjali Km. Prasad, Gautam Handique & Bipanchi Deka
Susceptibility of red spider mite, Oligonychus coffeae Nietner (Acari: Tetranychidae), collected from conventionally-managed (synthetic acaricide usage) versus an organicallymanaged (no acaricide usage) tea plantations in Assam, India, to five synthetic acaricides was determined in laboratory bioassays. Activity of three principal detoxifying enzymes of these mite populations was also assayed. The median lethal concentrations (LC50) of ethion, dicofol, propargite, fenpropathrin, and fenazaquin were 1049.75, 599.21, 232.03, 11.44, and 6.75 ppm, respectively. Field rates of these acaricides...

A new Aceria species (Acari:Trombidiformes: Eriophyoidea) from West Asia, a potential biological control agent for the invasive weed camelthorn, Alhagi maurorum Medik. (Leguminosae)

Biljana Vidović, Hashem Kamali, Radmila Petanović, Massimo Cristofaro, Philip Weyl, Asadi Ghorbanali, Tatjana Cvrković, Matthew Augé & Francesca Marini
A new species of eriophyoid mite Aceria alhagi n. sp. inhabiting the weed Alhagi maurorum Medik., is described from the type locality in Iran, but it was also collected from Uzbekistan, Turkey and Armenia. This mite causes changes of the leaves and inflorescence. Infested plants develop cauliflower-like galls on the inflorescence and leaves deforming the reproductive structures and inhibiting seed production. The potential reduction in seed set suggests that this mite could constitute a potential...

Julien K. N’Dri, Pacôme K. Pokou, Fabrice A. Séka, Rodolphe A. G. N’Da & Jan Lagerlöf
The objective of the investigation was to determine the response of different taxa of mites across the land use types and demonstrate that soil mites could be used as an indicator of environmental change after the conversion of secondary forests into rubber plantations. The sampling was performed during the dry season on 12 sampling areas, consisting of four land use types: secondary forests, 7-year-old rubber plantations, 12-year-old rubber plantations, and 25-year-old rubber plantations, with three...

Bisexual and oedipal reproduction of Macrocheles muscaedomesticae (Acari, Macrochelidae) feeding on Musca domestica (Diptera, Muscidae) eggs

Sara Farahi, Parviz Shishehbor & Alireza Nemati
Macrocheles muscaedomesticae (Scopoli) is a predatory mesostigmatic mite that inhabits different manure microhabitats and preys mostly on housefly (Musca domestica L.) eggs. When a virgin female colonizes a new manure substrate, it produces male offspring through parthenogenesis (arrhenotoky); when her sons reach maturity, oedipal mating takes place and the female begins to produce bisexual offspring. In order to examine the consequence of oedipal reproduction on population development, we designed two separate experiments to compare life...

Morphological observations of fluorescence in different tick species (Family: Ixodidae)

Dakota A. Shade
Ticks are important ectoparasites due to their ability to transmit harmful pathogens and their study is thus significant for medical and veterinary practices around the world. Fluorescence has been found in numerous biological organisms, including ticks. However, the overall function, evolutionary significance, and distribution of fluorescence in ticks are unknown. This study examined tick fluorescence in purchased, unfed adult Amblyomma americanum (Linnaeus), A. maculatum Koch, Dermacentor variabilis (Say), D. andersoni (Stiles), Ixodes scapularis Say, and...

Two Eocene species of peacock mites (Acari: Tetranychoidea: Tuckerellidae)

Ekaterina A. Sidorchuk & Alexander A. Khaustov
Tuckerellidae are suctorial plant feeders with a wide host range, exploiting both aboveground and underground plant parts. A new species, Tuckerella weiterschani n. sp., is described from Eocene (ca. 40 mya) Baltic amber, and Tuckerella fossilibus Khaustov, Sergeyenko and Perkovsky, 2014 from Eocene Rovno (Ukrainian) amber is redescribed, each based on single holotype specimens. The two mites are morphologically distinct, with most striking differences concerning posterior, H-row of idiosomal setae. Tuckerella fossilibus has unusually large,...

Use of predatory mites in commercial biocontrol: current status and future prospects

Markus Knapp, Yvonne van Houten, Elmer van Baal & Thomas Groot
Predatory mites play the leading role in commercial augmentative biological control. They are mainly used in protected vegetable and ornamental cultivation systems to control phytophagous mites, thrips and whiteflies. Use in open-field systems and in animal husbandry is still limited. Phytoseiidae species are by far the most important group of commercially available mite biocontrol agents with about 20 species offered worldwide. Out of these, Amblyseius swirskii, Phytoseiulus persimilis, Neoseiulus cucumeris and Neoseiulus californicus are the...

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...

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.

Andre V. Bochkov
eginabstractMites of the family Chirodiscidae (Acariformes: Sarcoptoidea) are permanent mono- or stenoxenous symbionts of mammals living in the fur of their hosts. Among three genera included in the tribe Schizocarpini (Labidocarpinae), members of the genus Lutrilichus Fain inhabit small carnivores of the families Mustelidae and Viverridae (Carnivora). The external morphology of postembrionic stages of Lutrilichus javanicus Fain, 1970 (Acariformes: Chirodiscidae), collected from Melogale moschata (Gray, 1831) (Mustelidae) in Vietnam, is described. This is the second...

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...

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...

Distribution of microarthropods across altitude and aspect in the sub-Antarctic: climate change implications for an isolated oceanic island

Elizabeth A. Hugo-Coetzee & Peter C. Le Roux
Current climate change is altering the distribution of species across both broad and fine scales. Examining contemporary species distributions along altitudinal gradients is one approach to predicting species future distributions, as species occurrence patterns at cold, high altitudes are expected to resemble the species distribution patterns currently observed at warmer, lower altitudes if warming occurs. Strong changes in climate have been observed in the sub-Antarctic over the last 50 years, with a 1.5 °C increase...
