First record of paguroid anomurans (Crustacea) from the Tithonian-lower Berriasian of Štramberk, Moravia (Czech Republic)

Abstract

For the first time, paguroid remains are recorded from the Tithonian (latest Jurassic) to early Berriasian (Early Cretaceous) Štramberk Limestone in the eastern Czech Republic. On the basis of carapaces and a sixth abdominal tergite, new representatives of the families Diogenidae (Bachmayerus cavus n. gen., n. sp.), Parapylochelidae (Housacheles timidus n. gen., n. sp.) and Pylochelidae (Pylochelitergites stramberkensis n. sp.) are named and described. Data are added on the morphology of a new member of the Gastrodoridae, Gastrodorus kotoucensis n. sp.; on the basis of this record, the family is reassigned, as a basal group, to the Paguroidea.
