A complementary description of Neoseiulus longilaterus (Athias-Henriot) is presented based on adult female specimens collected in Iran, marking the first record of this species in the country. Specimens of this species were collected in galls of an unidentified eriophyid mite on desert thorn leaves (Lycium shawii Roem. & Schult., Solanaceae). While Chant & McMurtry (2003) categorized this species within the cucumeris species group of Neoseiulus Hughes, its morphological characteristics align more closely with some species from the paspalivorus group. Therefore, we provisionally classify N. longilaterus within the paspalivorus group. In addition, an updated and revised key for identifying the known species in the latter group is also provided. We also consider N. engaddensis syn. nov. as a junior synonym of N. longilaterus.

Two new species of eriophyoid mites were found and described from south China: Shevtchenkella wudongensis sp. nov. and Rhinotergum largituberis sp. nov. Both new species infest Juglans regia L. (Juglandaceae) and are vagrants on lower leaf surface of host plants with no particular symptom.

A new mite species of the stigmaeid genus Eustigmaeus Berlese, 1910, E. asper sp. nov., is described from Honshu, Japan. Additionally, E. rhodomelus (Koch, 1841), which is broadly distributed in the Holarctic region, and E. pseudolacunus Khaustov, 2023, which was originally described from Russia, are recorded from Japan for the first time.

The present study is based on the oribatid mite material collected from litter in Limu Mountain National Forest Park in Hainan Island, China. A list of 55 species and four subspecies, belonging to 37 genera and six subgenera in 29 families, is presented. Among them, two genera and 17 species are newly recorded in China, and one new species, Phthiracarus limuensis sp. nov. (Phthiracaridae), is described. The new species is easily distinguished from other congeneric species by the presence of distinct median crista and longitudinally striae on surface of prodorsum. In addition, an identification key to all known species of Phthiracarus from China is presented.

A new genus Proathyreacarus gen. nov. with the type species Athyreacarus staturosus is described. The genus Athyreacarus is divided into three subgenera: Athyreacarus sensu stricto, Athyreacaroides subgen nov. with the type species Athyreacarus brevisetosus, and Parathyreacarus subgen. nov. with the type species Athyreacarus magnificus. Four new species are described: Proathyreacarus argentiniensis sp. nov. from Argentina phoretic on the beetle Zefevazia rosascostai (Bolboceratidae); Athyreacarus (Athyreacaroides) australiensis sp. nov. and A. (Athyreacaroides) squamosus sp. nov. from Australia phoretic on the bolboceratid beetles Australobolbus pseudobscurius and Australobolbus rotundatus rotundatus, respectively; and Athyreacarus (Parathyreacarus) aequalis sp. nov. from Bolivia phoretic on the beetle Neoathyreus lobus (Bolboceratidae). The Athyreacaridae was described from Australia for the first time. A revised and updated key to genera, subgenera and species of Athyreacaridae is also provided.
