Article Synopsis
  • - Parasitengona, a diverse group of mites including velvet mites and chiggers, consists of over 11,000 species found in various habitats and is significant due to certain species' roles as disease vectors.
  • - The classification of Parasitengona remains debated, with unclear boundaries between its superfamilies and families, while most species undergo metamorphosis, although the Allotanaupodoidea superfamily shows exceptions.
  • - A recent study conducted phylogenetic analysis suggesting that Parasitengona likely originated on land and led to a new classification within the superfamily Trombidioidea, proposing three new major divisions based on genetic relationships.

Eriophyoid mites represent a hyperdiverse, phytophagous lineage with an unclear phylogenetic position. These mites have succeeded in colonizing nearly every seed plant species, and this evolutionary success was in part due to the mites' ability to induce galls in plants. A gall is a unique niche that provides the inducer of this modification with vital resources.

Metamorphosis is a key innovation allowing the same species to inhabit different environments and accomplish different functions, leading to evolutionary success in many animal groups. Astigmata is a megadiverse lineage of mites that expanded into a great number of habitats via associations with invertebrate and vertebrate hosts (human associates include stored food mites, house dust mites, and scabies). The evolutionary success of Astigmata is linked to phoresy-related metamorphosis, namely the origin of the heteromorphic deutonymph, which is highly specialized for phoresy (dispersal on hosts).

This paper presents ten species of eight genera and four families (Ameroseiidae, Ascidae, Blattisociidae, Laelapidae) of soil-inhabiting mesostigmatic mites in Kazakhstan. Eight of them are species that are recorded for the first time in Kazakhstan: Ameroseius corbiculus (Sowerby, 1806), Antennoseius (Vitzthumia) oudemansi (Thor, 1930), Cosmolaelaps lutegiensis (Shcherbak, 1971), C. markewitschi (Pirianyk, 1959), Gaeolaelaps nolli (Karg, 1962), Laelaspis astronomicus (Koch, 1839), Lasioseius ometes (Oudemans, 1903), and Pseudoparasitus missouriensis (Ewing, 1909).

Eriophyoid, or four-legged mites, represent a large and ancient radiation of exclusively phytophagous organisms known from the Triassic (230 Mya). Hypothesizing phylogenetic relatedness of Eriophyoidea among mites is a major challenge due to the absence of unambiguous morphological synapomorphies, resulting in ten published hypotheses placing eriophyoids in various places in the acariform tree of life. Here we test the evolutionary relationships of eriophyoids using six genes and a representative taxonomic sampling of acariform mites.

This paper outlines an approach that we are taking for elder-care applications in the smart home, involving cognitive errors and their compensation. Our approach involves high level modeling of daily activities of the elderly by breaking down these activities into smaller units, which can then be automatically recognized at a low level by collections of sensors placed in the homes of the elderly. This separation allows us to employ plan recognition algorithms and systems at a high level, while developing stand-alone activity recognition algorithms and systems at a low level.
