Four new psychodid flies, Yantarpsychodus szadziewskii gen. et sp. nov., Sakhalinopsychoda krzeminskii gen. et sp. nov., Sakhalinopericoma russiaensis gen. et sp. nov., and Tonnoira sakhalinensis sp. nov. are characterised, illustrated and described from the Late Cretaceous Santonian Yantardakh amber and the Paleogene mid-Eocene Sakhalin amber.
