In an effort to understand the fauna of edaphic mites of the genus Lasioseius Berlese (Blattisociidae) from Brazil, a new species was found and it is here described as Lasioseius biota Barros & Castilho sp. nov. It is rather unusual among the Lasioseius species for having dorsal setae mostly bacillate or saber- to leaf-shapped. The other species considered in this paper is Lasioseius meridionalis Chant, morphologically known only from the original description, based solely on the holotype female (from USA). Information resulting from the reexamination of the holotype and on females collected from Brazil is provided. This is the first record of this species in Brazil. With this publication, the total number of Lasioseius species reported from Brazil adds to 19 and a key for the separation of females of these species is provided.

Mites belonging to the Syringophilidae family are a cosmopolitan and taxonomically diverse group of obligate and permanent parasites. These mites inhabit and reproduce within the hollow quills (calamus) of the wing, tail, and contour feathers. This study presents the first field observations of quill mites parasitising doves of the Turtur genus distributed in sub-Saharan Africa. A total of 145 host individuals from all five Turtur species (i.e., T. abyssinicus, T. afer, T. brehmeri, T. chalcospilos, and T. tympanistria) were examined during ornithological surveys conducted in Ghana, Uganda, Mozambique, and Nigeria. All examined bird species were found to be parasitised by a single oligoxenous syringophilid species, Meitingsunes tympanistria Skoracki & Dabert. Previously, this mite species had only been recorded from T. chalcospilos and T. tympanistria and from Tanzania and Togo; thus, the remaining dove species and countries of origin represent new host and locality records for this quill mite species. In our study, 20 individuals (13.8%) of the Turtur genus were infested by quill mites, with prevalence ranging from 8.8% to 24.2%. Mites were found to inhabit only the quills of wing coverts. No relationship was observed between the host body condition of two analysed host species (T. tympanistria and T. chalcospilos) and infestation by M. tympanistria. The fact that M. tympanistria exploits all representatives of the genus Turtur suggests that this mite species invaded these birds before their radiation, dating back approximately 15 Mya (Middle Miocene).

In recent decades, significant increases and/or drastic changes have been recorded in the prevalence, intensity, and distribution of ticks worldwide, which are known to be fueled by the climate change. However, there are many intertwined drivers affecting ticks, the degree of their influence of which is contingent and difficult to determine, and it is known that elucidating the factors is crucial to understand the current tick ecology and predicting the future trend. This study was carried out to determine monthly dynamics of tick infestation in owned and stray dogs under the influence of hot dry summer sub-type of the Mediterranean climate in Thrace region, European part of Turkey. During the survey performed in 2017 on monthly basis, 1605 different dogs from ten different localities in Thrace were examined for ticks. Infestation was determined in 137 (8.54%) dogs. The highest monthly prevalence (34.03%) was recorded in May. In total, 1033 ticks (1008 adults, 25 nymphs) belonging to the following species have been identified with different monthly and total prevalence and intensity: Rhipicephalus sanguineus sensu lato, Haemaphysalis parva, Ixodes ricinus, Ixodes acuminatus, and Ixodes kaiseri. The results indicated that degradation and destruction of natural habitats under the influence of human effect seem likely to cause/facilitate/accelerate the entering some wild animal species, and therefore their ticks, to the urbanized environments via afforested woodlands and gardens in the periurbans, and dogs in such areas seem to play a supportive role in the maintenance of some tick species, including those with primarily sylvatic cycle, such as I. acuminatus and I. kaiseri.

In this study, the investigation on oribatid fauna of agricultural region is carried out for the first time in Yangchun City, Guangdong Province, southeast China. A list of identified taxa, including 19 species from 18 genera and 15 families, is presented. Of these, one species, Dolicheremaeus variolobatus Hammer, 1981, is recorded in China for the first time. 13 species are newly recorded in Guangdong Province. A new species, Unguizetes yangchunensis sp. nov., is described. In addition, an updated key to all known species of Unguizetes is provided.

A new species viz. Molothrognathus acus sp. nov., collected from litter and soil under Pinus brutia (Pinaceae), Molothrognathus tauricus Khaustov, 2021 is recorded for the first time in Turkey and the unknown male of Prostigmaeus amplius Doğan et al., 2020, collected from litter and soil under Olea europaea (Oleaceae) in Manisa province, Türkiye, is described and illustrated. A key to the species of Molothrognathus from Türkiye is provided.

Storchia pacifica (Summers, 1964) is redescribed from specimens intercepted by staff of the Australian Department of Agriculture, Fisheries and Forestry from Cambodia, Fiji, India, Indonesia, Kiribati, Laos, Pakistan, Papua New Guinea, New Zealand, Nigeria, Samoa, Singapore, Solomon Islands, Tonga, Uganda, Vanuatu, and Vietnam. Most of the specimens were intercepted on products made from woven natural fibre such as mats and baskets. The specimens show variation in the form of their dorsal setae, which are slender and tapered to strongly clavate distally. Otherwise, dorsal and leg chaetotaxy is consistent, as is the characteristic pattern of body striation of this species.

Five mites of the genus Sennertia Oudemans, 1905: Sennertia alfkeni (Oudemans, 1900), Sennertia eximius sp. nov., Sennertia horrida (Vitzthum, 1912), Sennertia lauta Klimov and OConnor, 2007, Sennertia taiwanensis sp. nov., which are phoretic on carpenter bees (Genus Xylocopa) from Taiwan and Kinmen area, are described and illustrated. The species delimitation among the five Sennertia species using phylogenetic tree and genetic K2P distance analyses is well-defined. The species groups to which these bee mites belong, and their hosts in this area, are as follows: S. alfkeni (japonica-group): Xylocopa (Alloxylocopa) nr. appediculata, X. (Alloxylocopa) phalothorax and X. (Koptortosoma) ruficeps; S. eximius sp. nov. (cerambycina-group): X. (Biluna) auripennis, X. (Zonohirsuta) dejeanii and X. (Biluna) tranquebarorum; S. horrida (horrida-group): X. (Biluna) auripennis and X. (Biluna) tranquebarorum; S. lauta (horrida-group): X. (Zonohirsuta) dejeanii and X. (Biluna) tranquebarorum; S. taiwanensis sp. nov. (horrida-group): X. (Bombioxylocopa) bomboides.

A new feather mite species, Megniniella gruophila sp. nov., is described from the Common Crane, Grus grus (Gruiformes: Gruidae), in the Stavropol Krai, European Russia, and this is the first record of the genus Megniniella from the family of cranes. The new species is most close to M. ratcliffi Mironov and Galloway, 2002 and readily differs from this species in having the following features: in both sexes, supracoxal setae scx are absent; in males, the scapular shield lacks suprategumental extensions, the hysteronotal shield bears longitudinal striae only in a small area anterior to the supranal concavity; in females, setae c3 are situated off the humeral shields, coxal setae 4b are situated posterior to the tips of the epigynum, setae e2 do not extend to the posterior margin of the opisthosoma. Taxonomic notes on the genus Megniniella and corrections of its species contents are provided. The genus was established by Gaud (1958) without designation of a type species; therefore, according to Article 13.3 of the current code of the International Commission on Zoological Nomenclature (ICZN 1999), the authority and year of Megniniella should be referred to the subsequent paper where it was designated (Gaud & Mouchet 1959). Dimorphus calcaratus Haller, 1882, formerly included by Gaud (1968) in the genus Megniniella, is removed and placed in the genus Metanalges Trouessart, 1919 (Analgidae) with the new combination Metanalges (Agrialges) calcaratus (Haller, 1882) comb. nov. Megniniella porzanae Gaud, 1958 and M. limnocoracis Gaud and Mouchet, 1959, formerly synonymized by Gaud (1968) with Megniniella calcarata (Haller, 1882), are restored as valid species. The subspecies Megninia gallinulae maior Berlese, 1886, formerly referred by Hull (1934) to the genus Diplaegidia Hull, 1934 (Analgidae) and treated as a full species D. major, is transferred to the genus Megniniella with the new combination Megniniella maior (Berlese, 1886) comb. nov.
