New records of Micromegistus bakeri, Trägårdh 1948 (Acari: Mesostigmata: Parantennulidae), a mite symbiotic on carabid beetles, and notes on the species’ distribution and host specificity Open
Micromegistus bakeri is a purported commensal mite that spends most of its life on the ground beetle Scarites subterraneus. It is thought to sustain itself by feeding on the beetle’s dermal fluids and opportunistically scavenging on nearby…

Catalogue of the free-living and arthropod-associated Laelapidae Canestrini (Acari: Mesostigmata), with revised generic concepts and a key to genera Open
The cosmopolitan mite family Laelapidae includes both free-living predatory species and species associated with arthropods, mammals or birds. This work presents a list of free-living and arthropod-associated species of laelapids, with corr…

Feeding habits and multifunctional classification of soil‐associated consumers from protists to vertebrates Open
Soil organisms drive major ecosystem functions by mineralising carbon and releasing nutrients during decomposition processes, which supports plant growth, aboveground biodiversity and, ultimately, human nutrition. Soil ecologists often ope…

<strong>New morphological data for <em>Leonseius regularis</em> (De Leon) (Acari: Phytoseiidae) and a description of a new species of the genus from Brazil</strong> Open
The genus Leonseius Chant & McMurtry (Phytoseiidae: Typhlodrominae) was proposed to accommodate Typhloseiopsis regularis De Leon, 1965, a species with a troubled taxonomic history that was previously classified in the genera Typhlodromus S…

Review of the mite genus Ololaelaps (Acari, Laelapidae) and redescription of O. formidabilis Berlese Open
A species of laelapid mite, Ololaelapsformidabilis , is redescribed based on male and female adults from soil in Sumatra, Indonesia. This species is distinguished from other Ololaelaps species by its metapodal platelet narrowly fused with …

Acarine biocontrol agents Neoseiulus californicus sensu Athias-Henriot (1977) and N. barkeri Hughes (Mesostigmata: Phytoseiidae) redescribed, their synonymies assessed, and the identity of N. californicus (McGregor) clarified based on examination of types Open
In 1954, McGregor described two species of phytoseiids from lemon, in California, USA: Typhlodromus californicus McGregor and T. mungeri McGregor, the former represented by one male, and the latter by two females. Since its description, T.…

Spatial and temporal patterns of ground beetle (Coleoptera: Carabidae) activity across habitats at the Mont St. Hilaire Biosphere Reserve, Quebec Open
We investigated the seasonal variation and habitat preference of carabid beetles in mixed and hardwood stands, forest edge and meadow habitats at Mont St-Hilaire, southern Quebec, using pitfall traps from late May until the end of October …
