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...

Abstract Сomparative analysis of arthropod assemblages found in Cretaceous fossil resins is provided. Arthropod-bearing Cretaceous resin sites are reviewed, and a list of arthropod records (identified to the family level) published up to 2015 is provided. Also, new records of mites, and new arthropod records from the Siberian resins are given. An efficient method for extracting amber from loose sediments in situations of limited infrastructure but easy access to water is described as well. The s...

Summary Symbiosis [1], understood as prolonged interspecific association, is as ancient as the eukaryotic cell [2, 3]. A variety of such associations have been reported in the continental fossil record, albeit sporadically. As for mites, which as a group have been present since the Devonian (ca. 390 mya) [4, 5] and are involved in a tremendous variety of modern-day symbioses, reported associations are limited to a few amber-preserved cases [6–11], with the earliest instance in the Cretaceous (ca...

We describe a fossil member of Heterostigmata of Late Cretaceous age that is the first to show an unexpected array of primitive and derived attributes, some of which are perplexing for a member of this specialized group of trombidiform mites. In contrast, previously published records of heterostigmatic mites of similar age have been of fossils readily classified within moderately derivative superfamilies of this clade. With remarkably preserved details visible, our fossil is a male, from amber o...
