“…One hypothesis claims a separation of the terrane during the Devonian and a collision with Eurasia during the Jurassic, so that the amber forest would have been part of Eurasia during the Cretaceous. This view is to some degree supported by Müller et al (2019) in connection with the paleobiogeography of schizomids. Another hypothesis is that the West Burma terrane separated from Australia during the Jurassic and collided with Eurasia at ca.…”

“…Burmese amber is one of the most important geological archives for terrestrial arthropods from the Cretaceous and comprises representatives of all present-day arachnid orders (reviewed by Selden & Ren (2017): recently complemented by Müller et al (2019) with the first detailed description of a member of the Schizomida). This amber is mined in the Hukawng Valley in northern Myanmar.…”

Pseudoscorpions are amongst the oldest terrestrial lineages but there is a major gap in the fossil record between the oldest fossils from the Devonian (ca. 385 million years ago) and rich fossil communities in amber that mostly originate from the Eocene of Europe. Burmese/Myanmar amber (or Burmite) from the middle Cretaceous preserves a diverse community of pseudoscorpions but these remain poorly documented, despite their exceptional preservation and potential to offer unique insights into evolutionary history. Here we describe a new genus and species of pseudoscorpion with a unique morphology of the chelicerae, Prionochthonius burmiticus gen. et sp. nov., from Burmese amber. Although some key characters remain obscure, the fossil can be confidently attributed to the basal pseudoscorpion family Chthoniidae, but it cannot be assigned to any extant or other fossil genus. Based on trichobothria patterns, it is most similar to extant genera that are found only in the Southern Hemisphere; findings that are in line with previous studies suggesting Gondwanan origins for at least some of the Burmese amber invertebrates. The fossil provides further evidence for a diverse community of litter-and soil-dwelling pseudoscorpions in the Late Cretaceous that comprises many extinct genera but represents many of the modern families. It also suggests that the diversification of chthoniid pseudoscorpions occurred well before the middle Cretaceous, and that the principle gestalt of its members has changed relatively little over time.

Despite a global distribution throughout the tropics and sub-tropics, the order Schizomida (Arachnida) is heavily understudied and the phylogeny of the group is poorly understood. Identification keys are only available for some regions or genera but not for the entire order. (1) comprehensively reviewed the entire schizomid fauna and established a suite of characters to define all genera known at this time. This suite of characters still depicts the foundation of modern descriptions, supplemented by recently established characters, most of them documenting setation patterns on pedipalps, flagellum and chelicerae. In this paper, we present the Schizomida Trait Data Base (STDB) containing data for 25 characters based on the entire body of schizomid literature. Characters were chosen based on their use for modern taxonomic description and availability of the data. The STDB is a powerful tool that can be used by both amateurs and experienced researchers to categorise newly found specimens, both extant and fossil, down to genus level easily. Analysis using the new database gives insight into biogeographical patterns of characters. Furthermore, we are describing a new species, †Annazomus jamesi, a fossil specimen from Burmese (Kachin) amber and investigate a small collection of extant schizomids from Ecuador, which includes the previously unrecorded female of Surazomus palenque, herein described for the first time. The taxonomic assignment of both specimens is based on the STDB, highlighting the utility of the new data base approach to schizomid systematics.
