We describe two species of soil mite of the family Paratydeidae from the late Eocene Rovno amber: Scolotydaeus vlaskini sp. nov. and Tanytydeus pogrebnyaki sp. nov. This is the first formal descrip...

Abstract Microhymenopterans are important components of modern ecosystems, where they act as egg parasites and hyperparasites of arthropods. Mymarommatoidea are among the smallest hymenopterans and their actively flying adults have four wings, like all known members of the order Hymenoptera. Mymarommatoids were first described as fossils, and although their extant 12 species are distributed worldwide, little is known about their biology. They seem to be absent from the tropics presently, and onl...

A new species of the ectoparasitic mite genus Podapolipus Rovelli & Grassi, 1888 from a recently described species of the raspy cricket genus Chauliogryllacris Rentz, in Rentz and John,1990 (Orthoptera: Gryllacrididae) is described. The main distinctions of Podapolipus gryllacridi n. sp. from its described congeners from orthopterans are the larval female and adult male having all dorsal and ventral idiosomatic setae, except the greatly elongated pair of scapular setae (and the caudal setae of t...

Tetrapods are rarely recovered from fossil resins, such as amber, and fossils of parasites are even rarer. We describe the first pre-Quaternary co-occurrence of ectoparasitic mites with hairs of their mammalian hosts, preserved in life-like detail from a piece of Eocene (∼ 40 Ma) Baltic amber. The mites, representing the oldest fossils of the family Myobiidae (Acari: Prostigmata: Eleutherengona), are described as Protohylomysobia erinaceophilus Sidorchuk & Bochkov gen. et sp. nov. and belong to ...

Preparation of a piece of amber is an inevitable step for any paleontologist working with this precious medium. To see the life-like detail of a biological inclusion, the fossil resin itself has to be trimmed to the minimum, then surfaces polished flat for viewing of the fossil, preferably from all sides. This concerns inclusions of any size, but the smallest—mites, collembolans, scale insects and others—are the most challenging to the abilities of the human hand. Making a millimeter-large cube ...

ABSTRACTSmallness being in the essence of a mite, the question is whether it has always been so during the geological history of Acari. Here I assemble measurements of over 260 published mite fossils, distributed from the Early Devonian (410 mya) to the end of the Neogene (5 mya), and compare them to the data available for their extant relatives. A number of fossils are reconsidered: reports of the Ordovician Brachypylina and Permian Astigmata have to be excluded from the fossil record; Jurassic...

Abstract The oldest-known member of a small parasitic mite family Pterygosomatidae (Trombidiformes: Eleutherengona) was found in the Lower Cretaceous (Albian) amber locality of Archingeay-Les Nouillers in Charente-Maritime, France. The majority of the extant members of the family are obligate parasites of lizards, and only one genus of twelve, Pimeliaphilus Tragardh, 1905, is known to infest arthropods – kissing bugs, scorpions, beetles and cockroaches. The excellent preservation of the fossil, ...

Tuckerellidae are suctorial plant feeders with a wide host range, exploiting both aboveground and underground plant parts. A new species, Tuckerella weiterschani n. sp., is described from Eocene (ca. 40 mya) Baltic amber, and Tuckerella fossilibus Khaustov, Sergeyenko & Perkovsky, 2014 from Eocene Rovno (Ukrainian) amber is redescribed, each based on single holotype specimens. The two mites are morphologically distinct, with most striking differences concerning posterior, H-row of idiosomal seta...

This is the first record of the intentional consumption of moss spores by an arthropod. A moss mite Kunstidamaeus lengersdorfi (Oribatida: Damaeidae) was observed in Moscow Province, Russia, as regularly visiting mature capsules of the moss Schistostega pennata (Schistostegaceae) and eating spores from the opened capsules. The spores of Schistostega are thin-walled, sticky, not dispersed by wind, and exposed at the capsule mouth for easy consumption, being very similar in this respect to the spo...
