During a short research trip to Armenia in May 2015, 19 spider species were collected. Of them, 15 are new to the fauna of Armenia.

Pseudoscorpiones is one of the oldest arachnid orders, known in the palaeontological record since the Middle Devonian (c. 390 Ma). The following reliable indications of fossil pseudoscorpions occur in Early Cretaceous amber: Lebanese amber (c. 135–125 Ma), Spanish Álava amber (c. 113–100 Ma), Archingeay amber (c. 100 Ma) and Burmese amber (c. 99 Ma...

In this paper, 11 families (Agelenidae, Filistatidae, Hahniidae, Liocranidae, Mimetidae, Mysmenidae, Oecobiidae, Pholcidae, Phrurolithidae, Sparassidae and Uloboridae), 18 genera and 18 species of spiders new to Armenia are reported. one genus, Mesiotelus Simon, 1897 (Liocranidae) is new to the entire Caucasus. Illustrations are provided for six sp...

Miniaturization is one of the important trends in the evolution of terrestrial arthropods. In order to study adaptations to microscopic sizes, the anatomy of the smallest insects was previously studied, but not the anatomy of the smallest mites. Some of the smallest mites are Eriophyidae. In this study we describe for the first time the anatomy of...

Miniaturization is an evolutionary trend observed in many animals. Some arachnid groups, such as spiders and mites, demonstrate a strong tendency toward miniaturization. Some of the most miniaturized spiders belong to the family Anapidae. In this study, using light and confocal microscopy and 3D modelling, we provide the first detailed description...
