The family Parasitidae (Acari: Mesostigmata) - history, current problems and challenges

Kamila Hrúzová & Peter Fenďa
The family Parasitidae comprises two subfamilies, Parasitinae and Pergamasinae. A generic concept of this family is not stable and requires a revision. The number of genera varies depending on authors and their view on the systematics of the family, especially on the rank of taxa. We recognize 23 genera within Parasitinae and 22 genera within Pergamasinae, 4 of them are subdivided into subgenera. A dichotomous key for separation of genera and subgenera is provided. A...

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...

G.C.P. Diyes, N.B. Karunarathna, T.H.S.E. Silva, W.A.I.P. Karunaratne & R.S. Rajakaruna
Many pathogens, parasitoids and predators have been documented as natural enemies of ticks, but their impact on tick populations are rarely evaluated. Here, we report the predatory behaviour of ants on the spinose ear tick, Otobius megnini. Ticks were collected from the ear canal of stabled horses in Nuwara Eliya and were brought to the laboratory. Eggs, unfed and engorged larvae, engorged nymphs and adults were naturally exposed to ants under laboratory conditions and the...

Nasal mites from specimens of the brown-headed cowbird (Icteridae: Molothrus ater) from Texas and Arkansas, U.S.A.

Alexis D. Hilario-Pérez & Ashley P.G. Dowling
Avian nasal mites are obligate parasites that spend their entire life in the respiratory system of birds. In North America, four families in three orders parasitize birds: Rhinonyssidae (Mesostigmata), Ereynetidae (Prostigmata), Cytoditidae (Astigmata) and Turbinoptidae (Astigmata). Mechanisms of nasal mite transmission among hosts is still unclear and brood parasites like the Brown-headed Cowbird (Molothrus ater Boddaert, 1783), which utilize multiple bird species as hosts, are interesting for the study of parasites such as nasal mites....

Changes in a soil microarthropod community in the vicinity of dominant tree species under trampling management at the Safari Zoological Center, Israel

Rentao Liu, Roy Meller & Yosef Steinberger
Tree-canopy and trampling management are reported to influence soil arthropod abundance and diversity. However, there is limited understanding of their interactive effects on a soil microarthropod community at the Safari Zoological Center, central Israel. This study assessed the spatial influence of three dominant tree species (Cupressus sempervirens, Eucalyptus camaldulensis, and Tamarix aphylla) under contrasting trampling and enclosure treatment on soil microarthropod abundance and diversity during a wet Mediterranean winter. There was a significant interactive effect...

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...

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...
