A new species of canestriniid mite belonging to the genus Ciprusenia Haitlinger, 2022 is described based on the morphological characteristics of male, female, tritonymph, protonymph and larva life stages. It is the sixth species of this genus and was collected from Blaps bushirensis Kaszab, 1959 (Coleoptera: Tenebrionidae) on the surface soil of Sahlak Cave (Fars, Iran). The genus Ciprusenia is a new record for the Astigmata fauna of Iran and the host species is a new host record for the family Canestriniidae. In this study, descriptions are carried out in detailed line drawings and scanning electron microscopic images. The identification key to the world-known species of the genus is also provided.

The genera Aplonobia and Paraplonobia are redefined due to confusion surrounding the classification of several morphologically intermediate species. Following our revision of these genera, their distinction is based on the form of the peritremes, which are anastomosing in Aplonobia and simple in Paraplonobia. As a result, the subgenus Paraplonobia (Anaplonobia) is treated as a synonym of Aplonobia and the subgenus Parapolonobia (Brachynychus) is moved to Aplonobia. A new species of Aplonobia, namely Aplonobia aria sp. nov., is also described and illustrated based on females and a deutonymph collected from Haloxylon ammodendron (Amaranthaceae) in Southern Iran (Kerman Province). Aplonobia tabukensis (Kamran and Alatawi, 2016) is also recorded for the first time from Iran. Paraplonobia (Anaplonobia) ambrosiae (Tuttle, Baker and Abbatiello, 1976) [preoccupied by Aplonobia ambrosiae (Tuttle and Baker, 1968)] is renamed Aplonobia neoambrosiae nom. nov.

Eutrombidium parishanensis Kiany, Seiedy and Hakimitabar sp. n. (Acari: Microtrombidiidae: Eutrombidiinae) is described and illustrated from ectoparasitic larvae found on Sphodromerus luteipes (Orthoptera: Acrididae: Calliptaminae) from Iran. This species belongs to the species group of Eutrombidium, in which lateral coxalae I and coxalae II and III are small and have an incision in their distal half. The current study raises the number of described species in this genus to 45.

This paper reports on eriophyoid mites of the genus Aceria Keifer (Eriophyoidea, Eriophyidae) associated with Tamarisk plants (Tamarix spp., Tamaricaceae) in Egypt and South Africa. Three new Aceria species are described: A. aegyptytamaricis n. sp. causing green galls on buds and twigs of Tamarix senegalensis DC. in Egypt, A. noorspoortiensis n. sp. causing bright pink galls on young shoots of T. usneoides E. Mey. ex Bunge in South Africa, and A. benhaiensis n. sp. living under scaly leaves and causing small green galls and deformation of twigs on T. senegalensis in Egypt and T. usneoides (in South Africa). Sequences of three genes, Cox1, D1D2 28S, and ITS1-5.8S-ITS2, were obtained for A. noorspoortiensis n. sp. and A. benhaiensis n. sp. Blastx search for Cox1 sequences of both new species against Aceria from GenBank (a) indicated the sequence AIT38252.1 of Aceria sp. from Tamarix sp. from India as the most similar with 87–90% identity and 55–56% coverage and (b) revealed one codon deletion about 500 bp in the 3′ direction from the Cox1 start codon, which is the first documented case of a codon deletion in the middle part of this gene in Eriophyinae. Additionally, supplementary descriptions of three other Aceria spp. collected from tamarisks in Egypt are given. They are: A. amrini Joshi from big brown galls of T. aphylla (L.) H. Karst. (first record for Africa), A. dioicae (Keifer) from green galls on buds and twigs of T. senegalensis, and A. tamaricis (Trotter) from green galls on buds and twigs of T. senegalensis (first record for Africa).
本文报道了在埃及和南非与柽柳科柽柳属植物(柽柳属，柽柳科)有亲缘关系的针叶螨属。报道了三种新的针叶虫种:埃及柽柳(aaegyptytamaricis n. sp.)，在塞内加尔柽柳(Tamarix senegalensis DC)芽枝上产生绿瘿。在埃及，noorspoortiensis n. sp.在T. usneoides E. Mey.幼芽上引起亮粉色的瘿。生活在鳞片状叶子下的benhaiensis n. sp.在埃及的T. senegalensis和南非的T. usneoides上造成小绿瘿和树枝变形。在GenBank中对这两个新种抗针叶虫的Cox1序列进行了Blastx搜索(a)，发现印度柽柽树属针叶虫的Aceria sp.的序列AIT38252.1最相似，同源性为87-90%，覆盖率为55-56%;(b)在Cox1起始密码子3′方向缺失约500 bp的密码子。这是第一个记录在案的该基因中部密码子缺失的案例。此外，还对从埃及柽柳中采集的其他三种柽柳属植物进行了补充描述。它们是:A. amrini Joshi来自金黄色葡萄球菌(T. aphylla, L.)的大棕色瘿。h .岩溶。(非洲第一次记录)，A. dioicae (Keifer)来自T. senegalensis芽和枝上的绿色瘿，A. tamaricis (Trotter)来自T. senegalensis芽和枝上的绿色瘿(非洲第一次记录)。

The feather mite Pterolichus obtusus Robin, 1877 (Astigmata: Pterolichidae) is associated with Gallus gallus domesticus (L.) worldwide. Here, we report new records of this species from rustic chickens in Brazil after a gap of 45 years, and for the first time in a northern area of this country. The major role of Brazil as one of the main chicken meat producers and exporters highlights the importance of these new findings. Knowing and keeping track of the distribution of this ectoparasitic species might offer valuable information for the development of animal health programs and policies aimed at mitigating mite pest infestations, in addition to support decision-making processes regarding research funding to study the damage caused by P. obtusus in domestic and wild fowl populations, contributing to the advancement of aviculture.

Two new species of oribatid mites of the genus Trichogalumna Balogh, 1960 (Acari: Oribatida: Galumnidae), Trichogalumna pseudoohkuboi sp. nov. and Trichogalumna vittateata sp. nov. are described from China based on adult morphology. Trichogalumna pseudoohkuboi sp. nov. can be distinguished from other closely related species by the very small porose areas A2 and A3 on the notogaster, the surface of gnathosoma with large granules, five pairs of epimeral setae and epimeral setal formula 1-0-2-2, wide granular band on notogaster with the central part extending forward, the base of pteromorphs smooth, the surface of notogaster porose areas without stripes and the surface of genital plate with stripes. Trichogalumna vittateata sp. nov. is characterized by notogaster with four pairs of very small porose areas, the presence of longitudinal stripes on prodorsum, and the surface of pteromorphs with distinct ridge-like stripes.

Studies on the mites from the Franz Josef Land Archipelago have become strongly belated and impeded because of the archipelago’s highly remote location (1,500 km from the mainland) and logistics barriers. Material collected during five expeditions (1981−2016) has revealed a total of 48 species of free-leaving mites, yet two species are added based on literature data (absent in the present material). Altogether, 17 families, 22 genera, and 23 species are reported for the first time to inhabit the archipelago. The presence of 16 from 26 previously recorded species must be confirmed. Like in the other parts of the polar desert zone, arachnids (52 species, including two spider species found in previous works) generally appear to be more diverse than insects (14 species, found in previous and present works), this being a unique feature of that natural zone. Prostigmatic mites (19 species) are twice as diverse as oribatid mites (10 species). The mesostigmatic mite genus Arctoseius Thor, 1930 is the most species-rich (8 species of all 13 mesostigmatic mite species collected), as previously reported throughout the Arctic. The acarofauna is strongly fragmentary, 23 of all 30 genera (76.7%) being represented by one species each. The fauna of Mesostigmata is much more specialized (in terms of cryophily) in comparison to Oribatida, true arctic and arctic-montane species amounting to 92% versus 10%, respectively. The total mite abundance varies between 120 and 3,760 ind./dm2, being the maximal in a tundra-like habitat on a south-faced slope in Tikhaya Bay, Hooker Island. Small and thin-tegumented members of Eupodidae, Tydeidae and Nanorchestidae, all using liquid food alone, predominate everywhere across the archipelago as they do throughout the polar deserts of both Hemispheres. Small oribatids (Liochthonius spp., Brachychthoniidae) are often also abundant. All these taxa represent the most ancient lineages of the superorder Acariformes known to date back to the early or middle Devonian. The rather large and well-sclerotized members of the oribatid family Ceratozetidae are abundant only in the best heated habitats with an extended vegetation season.
