Abstract
A new genus and species of trigonotarbid (Arachnida: Trigonotarbida) is described from the late Carboniferous (Middle Pennsylvanian, Moscovian) of the Pilsen Basin in the Czech Republic. Doubravatarbus krafti gen. et sp. nov. is assigned to the family Aphantomartidae and is principally diagnosed by its relatively long and gracile legs compared to other trigonotarbids such as for example Eophrynidae and Anthracomartidae.
The specimen is preserved in pale grey volcanic ash fall deposits, a type of entombment which is presumably responsible for the instant burial and nearly complete preservation of the trigonotarbid's body. Its possible habitat in the original ecosystem is discussed in relation to the associated flora and its taphonomic implications.
