Abstract

Here we describe two new fossil species and one new genus of pseudoscorpions, found in the late Eocene Baltic amber. Baltochthonius andrushchenkoi gen. et sp. nov. and Heterolophus eridanus sp. nov. are assigned to the subfamily Tridenchthoniinae (Pseudoscorpiones: Chthoniidae). We present an updated diagnostic key for the tribes, genera and subgenera of Tridenchthoniinae. The biogeographic, paleohabitat and ecological features of new species are presented and compared to the related extinct and extant species of the subfamily Tridenchthoniinae.
