  First fossil of the pseudoscorpion family Chernetidae Menge, 1855 (Arachnida, Pseudoscorpiones) from mid-Cretaceous Burmese amber Abstract Pseudoscorpions ( Arachnida : Pseudoscorpiones ) are amongst the oldest terrestrial lineages but their fossil record is still very sparse. In recent years, Upper Cretaceous Burmese amber has emerged as an important source for fossil pseudoscorpions. In this study, we extend the fossil record of the family Chernetidae Menge, 1855 – one of the most diverse pseudoscorpion families – by at least 20 million years through the description of a new genus and species, † Burmachernes gen. nov . for the new species † Burmachernes cenomanium sp. nov . from this amber deposit. Although † Burmachernes exhibits the principle synapomorphy of Chernetidae , namely venom glands in the movable chelal finger, it is distinguished from all 121 extant genera as well as the Eocene fossil genus † Oligochernes Beier, 1937 by a unique combination of characters, inc...
