New Larval Cases of Caddisflies (Insecta: Trichoptera) from the Albian of Western Siberia

New fossil caddisfly larval cases from the Albian of Western Siberia (Kemerovo Region, Dmitrievka locality) are described: a new indusigenus Plumatindusia Sukatsheva et Vasilenko, indusigen. nov. with a new species Pl. vinogradovi Sukatsheva et Vasilenko, sp. nov., Folindusia (s. str.) singularia Sukatsheva et Vasilenko, sp. nov., and Folindusia (Profolindusia) syncarpia Sukatsheva et Vasilenko, sp. nov. The material indicates the allochthonous character of oryctocenoses and supplements the scarce data on mid-Cretaceous insects of Western Siberia. The work highlights the importance of larval cases as indicators of paleoenvironments.
