The Tydeidae fauna of the Altay (Altayskiy Kray and Respublika Altay) is reviewed. A total of nine species of the genus Brachytydeus were found. Among them, Brachytydeus montanus sp. n., B. altaicus sp. n. and B. brevisetosus sp. n. are new to science. Brachytydeus politus (Kuznetsov), B. reticuloinsignius (Kazmierski and Panou) and B. sleipneri (Momen and Lundquist) comb. n. are recorded from Russia for the first time. Brachytydeus arkadiensis (Panou and Emmanouel), B. magus (Kuznetsov) and B. woolleyi (Baker) are reported from Altay for the first time.

The genus Raphignathus Dugès (Acari: Raphignathidae) of Asian Russia is reviewed. Raphignathus sakhalinensis sp. n. is described based on female and male specimens collected from spruce bark on Sakhalin Island; R. longipes sp. n. is described based on female and male specimens collected from various regions of Russia (Bashkortostan, Tyumenskaya Oblast, the Respublika Altay and Kamchatka). Raphignathus fani Doğan and Ayyildiz and R. ozkani Doğan are recorded from Russia for the first time and redescribed. Raphignathus gracilis (Rack) is recorded from Asian Russia for the first time. A key to the species of Raphignathus of Russia is also provided.

Phoretic deutonymphs of Winterschmidtia tawantinsuyuca sp. n. (Acari: Winterschmidtiidae) are described from Peru. This is the fourth species of the genus recorded in the Neotropical realm. Similar to the three other Peruvian species, the new species is phoretic on bark beetles, but this is the first finding of Winterschmidtia on the beetles of the genus Xyleborus (Coleoptera: Curculionidae: Scolytinae). The new species differs from all others in the ornamentation on of its prodorsal shield.

We describe unusual heteromorphic deutonymph of Mycetinopus striatipedis gen. and sp. n. (Acari: Acaridae) phoretic on the handsome fungus beetle Mycetina marginalis (Coleoptera, Endomychidae) in the Eastern Palearctic. These deutonymphs have a unique combination of character states that make them very distinct in the family Acaridae: an unpaired pigmented spot
on the anterior propodosoma is present; supracoxal setae scx filiform and bifurcate; genu I with two solenidia; tibia-tarsi I–II are distinctly elongated and striated; vertical setae ve are present, and tarsal setae aa are lacking. Our work emphasizes the importance of continued exploration and documentation of the biodiversity of astigmatid mites associated with invertebrate hosts.
