New Caddisflies (Insecta, Trichoptera) of the Families Vitimotauliidae and Philopotamidae from the Khasurty Locality (Lower Cretaceous, Russia) with a Brief Review of the World Fossil Fauna

摘要

New representatives of the family Vitimotauliidae (Multimodus amplussp. nov.,Purbimodus parvulussp. nov.,Burimodus novusgen. et sp. nov.) and a new species of the family Philopotamidae (Juraphilopotamus callidussp. nov.) from the Lower Cretaceous of Russia (Republic of Buryatia, Khasurty locality) are described. Keys to of genera of the family Vitimotauliidae and species of genera ofPurbimodusandJuraphilopotamus, as well as tables showing geological and geographical distribution of fossil caddisflies of families Vitimotauliidae and Philopotamidae, are given. The analysis of the stratigraphic distribution of caddisflies indicates that the age of the Khasurty deposits is no younger than the beginning of the Early Cretaceous.
