“…It is hygrophilous [47], with some range of tolerance towards moisture [48], but according to Rajski [23], with narrow tolerance towards pH and preferences of its low values. The acidity is considered the main factor for abundant occurrence of N. coronata, and this species has been mainly reported from raised bogs and swamps [15,[17][18][19][20]22,[49][50][51][52][53][54][55][56][57], less from other acidic forest soils and heaths [8], and it was absent from eutrophic mires [49,58]. Some studies show however that it has been abundant in beech forests [59], deciduous and birch forests [60], and in Scots pine forests [61].…”

Nanhermannia coronata Berlese, 1913, is a common and abundant oribatid species in peatlands but can be easily mistaken for N. sellnicki Forsslund, 1958, as an adult. Therefore, the identity of adults of N. coronata from several sites in Norway and Ireland was supported by the COI sequence data, and based on this material, the morphological ontogeny of this species is described and illustrated to highlight the differences between N. coronata and N. sellnicki. In all juvenile stages of N. coronata, the bothridial seta is absent, but two pairs of exobothridial setae are present, including short exp and exa reduced to its alveolus. In the larva, seta f1 is setiform, but in the nymphs, it is reduced to its alveolus. Most prodorsal and gastronotal setae of larva are short, and of nymphs they are long. In all instars, the leg segments are oval in cross section and relatively thick, and many setae on tarsi are relatively short, thick and conical, except for longer apical setae. Seta d accompanies solenidion σ on all genua, φ1 on tibia I and φ on other tibiae. We found some morphological characters that clearly differentiate N. coronata from N. sellnicki, like the number of setae on femora of adults and tritonymphs, the shape of insertions of prodorsal seta in and all gastronotal and adanal setae of juveniles; in N. sellnicki, these setae are inserted in small individual depressions, whereas in N. coronata, these depressions are absent. Our ecological observations confirm a common occurrence of N. coronata in raised bogs, a high percentage of juvenile stages in its populations and a preference of this species for humid microhabitats, whereas N. sellnicki is less common than N. coronata and occurs in drier habitats.

The present study is based on oribatid mite material (Acari, Oribatida) collected from moss (Sphagnum sp.) on the seepage area below a permanent spring in South Africa. A list of identified taxa, including 17 species from 15 genera and 11 families, is presented; of these, six species (Haplochthonius simplex, Trhypochthoniellus longisetus, Tyrphonothrus maior, Neoamerioppia polygonata, Trachyoribates ovulum, Trichogalumna nipponica) and three genera (Haplochthonius, Trhypochthoniellus, Trachyoribates) are recorded in the fauna of this country for the first time, and three species (Malaconothrus hexasetosus, Mucronothrus braziliensis, Limnozetes ciliatus,), three genera (Mucronothrus, Limnozetes, Nesozetes) and one family (Nesozetidae) are recorded in the Ethiopian region for the first time. Two new species belonging to the genera Trhypochthoniellus and Hydrozetes are described. Trhypochthoniellus malaconothroiformis sp. nov. differs from the morphologically most similar species, Trhypochthoniellus ramosus Hammer, 1982 by the absence of strongly branched notogastral and leg setae, and the presence of seven pairs of genital setae. Hydrozetes sphagnicolus sp. nov. differs from all known species of Hydrozetes by the much longer notogastral setae with attenuate tips.

Memoirs of the Entomological Society of Canada 169:13 -88 (1994) This paper reviews and summarizes preliminary data on the taxonomy, distributionr and ecology of oribatid mites of Canadian peatlands, primarily those of eastem Canada. This fauna is a heterogenous assemblage comprising 7 1 species in 49 genera and 34 families, found in four main types of habitats: aquatic, mesic, xeric, and epigeal. About half ofthe oribatid fauna of peatlands, and most aquatic species, are restricted in distribution to the Nearctic. Oribatid taxa known or suspected to be parthenogenetic are much better represented in peatlands than in the general Canadian fauna. Data on the feeding habits of odonate Iarvae in Newfoundland bog pools, based on gut content analysis, show that oribatid mites, in particular species of Limnozetes Hull and Hydrozetes Berlese, are common prey of species of Aeslzna Fabricius, Leucorrhina Brittinger, and Libellula L.
