RESUMO
The new genus Pedoniphis gen. nov. (Acari: Mesostigmata: Eviphididae) is described from soil detritus in Sabalan Mountains, northwest Iran, with P. persicus sp. nov. as type species. Among known eviphidid genera, the new genus is the most similar to Scamaphis Karg and Scarabacariphis Masán and it can be distinguished especially by the dorsal chaetotaxy (setae J2 absent, setae J5 rudimentary) and the specific form of the peritrematal-dorsal scutal complex (peritrematal shields reduced; peritremes well developed, fused to lateral margins of dorsal shield).

Varroa mites, notorious for parasitizing honeybees, are generally classified as Varroidae. Their extremely modified morphologies and behaviors have led to debates regarding their phylogenetic position and classification as an independent family. In this study, two different datasets were employed to reconstruct the phylogenies of Varroa mites and related Laelapidae species: (1) 9257 bp from the whole 13 mitochondrial protein-coding genes of 24 taxa, (2) 3158 bp from 113 taxa using Sanger sequencing of four nuclear loci. Both mitochondrial and nuclear analyses consistently place Varroa mites within the Laelapidae. Here we propose to place Varroa mites in the subfamily Varroinae stat. nov., which represents a highly morphologically adapted group within the Laelapidae. Ancestral state reconstructions reveal that bee-associated lifestyles evolved independently at least three times within Laelapidae, with most phoretic traits originating from free-living ancestors. Our revised classification and evolutionary analyses will provide new insight into understanding the Varroa mites.

This paper reports on five species of mites of the genus Gymnolaelaps associated with ants and soil in Iran--G. artavilensis sp. nov. from Pheidole pallidula, G. laevis (Michael) and G. myrmecophilus (Berlese) from Tetramorium caespitum, G. myrmophila (Michael) from Formica sp., and G obscuroides Costa from soil. Gymnolaelaps australicus Womersley and G. hospes (Berlese) have also been reported from Iran, in association with P. pallidula, but those records are incorrect. A key to the species of Gymnolaelaps occurring in the Western Palaearctic Region is presented. We review the related genus Laelaspisella Marais & Loots, and transfer Gymnolaelaps kabitae Bhattacharyya and G. canestrinii (Berlese) sensu Costa to Laelaspisella.

The new species is described and illustrated based on morphological characters of the adult females and males and compared with known congeners. This new species is the first record of Julolaelaps from Republic of Korea. In addition, an updated key to all known species of the genus is presented.
RESUMO
Although the juvenile instars of oribatid mite family Lohmanniidae are well known compared to the other families of the infraorder Enarthronota, information on morphological ontogeny most known species is still lacking. Herein, a new species of the genus Lepidacarus is proposed from soil-litter of the Maafushi Island, Maldives, based on all ontogenetic instars. A comparative analysis of ontogenetic instars of species belonging various genera of Lohmanniidae is given, and the major characteristics of juvenile instars of 21 species are presented. From this analysis, it can be generalized that the juvenile morphologies of lohmanniid genera are quite similar and uniform, there is no significant features separating different genera of Lohmanniidae, and the juveniles of various genera differ from one another in the same characteristics as the adults.

This study provides additional morphological information and new illustrations for three species of Ololaelaps Berlese described by Bregetova Koroleva (1964) from RussiaO. caucasicus, O. sellnicki and O. ussuriensisto supplement the original descriptions. Since holotypes for these three species were not designated, a lectotype is chosen from among the syntypes of each examined species. We describe the adult male and female of Ololaelaps altaiensis Joharchi sp. nov., from specimens collected from moss on the shore of the Teletskoye Lake, in Altai Mountains, Russia. The new species is distinguished from other Ololaelaps species by its short peritremes, ending near the middle of coxae II. The new species also has elongate paradactyli, extending well beyond the pretarsal claws; this feature appears to be correlated with the species semiaquatic habitat, and such correlation between tarsal morphology and ecology occurs in other species of Ololaelaps and of Gaeolaelaps with similar habitats.

We describe a new monotypic genus in the mite family Laelapidae, Hyposternus gen. nov., to accommodate a new species, H. ceylonicus sp. nov., on the basis of female, male and protonymph specimens collected from soil-litter in Sri Lanka. The female of the new genus differs from other genera of Laelapidae by having a strongly desclerotised sternal shield, essentially represented by a narrow anterior and lateral sclerotised ridges. Other distinctive features of the new species include the absence of dorsal shield seta z3, an epistome projecting anteriorly, movable digit of the chelicera tapered apically, an elongate anal shield, thorn-like opisthogastric setae, an anteriorly widened hypostomal groove, and long dorsal macrosetae ad1 on femora IIIV.

We describe a new genus in the mite family Melicharidae, Mycomelichares Masán Joharchi gen. nov., to accommodate two new species, Mycomelichares polypori Masán Joharchi sp. nov. and Mycomelichares reductus Masán Joharchi sp. nov. on the basis of specimens collected on wood-decaying fungi and/or mycophagous beetles of the genera Triplax Herbst and Tritoma Fabricius (Coleoptera: Erotylidae) in Slovakia and European part of Russia, respectively. Moreover, two previously described Proctolaelaps species-P. cyllodi Samsinák, 1960 and P. slovacus Masán, 1998 are transferred to the newly established genus. The new genus is characterized by specific characters in tritosternum (enlarged and brush-shaped, having their laciniae thickened, basaly fused and distally densely pilose), chelicerae (slightly dish-shaped digits with long, narrow and sharp denticles), ventral hypostome (setae h1 enlarged, thickened and distally flattened), setation (tendency towards placement of R series setae on soft integument, and reduction of some setae on idiosoma and legs), and unusual ecological specialisation on fungal substrates. Mycomelichares polypori sp. nov. is adapted to the life in sporophores of the basidiomycete bracket fungus, Polyporus squamosus (Polyporaceae). Mites of this species can be abundantly found on the lower fertile surface of the fungus, including large spore-bearing pores. Furthermore, keys to the melicharid genera reported from Palaearct, and the species of the genus are provided.

This paper reports on three species of mites of the genus Gaeolaelaps from Altai Mountains, Russia. Gaeolaelaps altaiensis sp. nov., G. lenis Vatankhah Nemati were collected from nests of Lasius sp. and Formica sp. (Hymenoptera: Formicidae), respectively, and G. euparadactylifer sp. nov. from moss on the shore of the Teletskoye Lake. The new species have the unusual character state of short peritremes, ending near the middle of coxae II. In G. euparadactylifer sp. nov., the pretarsal paradactyli on legs II-IV are strongly elongated, apically pointed and with their tips projecting well beyond the claws. Both new species are described based on morphological characters of the adults. In addition, the male of Gaeolaelaps lenis is described for the first time.

Typhlodromus (Anthoseius) tetraporus sp. nov., collected on grasses in Crimea, is proposed as a new species for science. The new species can be separated from all known species of Typhlodromus (Anthoseius) by the combination of following characters; peritreme extending almost to level of setae j1, four pairs of solenostomes on dorsal shield, two pairs of setae on sternal shield, a sclerotised v-shaped plate posterior to sternal shield, four pairs of pre-anal setae, a pair of small rounded pre-anal solenostomes, differentiated and larger atrium of spermatheca and eight setae on genu II. In addition, T. (A.) montanus Chant Yoshida-Shaul (Acari: Phytoseiidae), a species only known based on its original description from Canada is reported for the first time in Russia. The new record is redescribed and illustrated based on female specimens collected from Prunus padus L. (Rosaceae) where it was associated with eriophyid mites in Pereval Seminskiy, Altai Republic. This species may be an important predator as a potential biological control agent of eriophyid mites.
