摘要：
A new caddisfly species, Khasurtia apertalocularis sp. nov., and a Dysoneuridae gen. indet. sp., are described and illustrated, and Utania defecta Sukatsheva, 1982 is redescribed, based on 13 fossil specimens from the Lower Cretaceous Yixian Formation of Inner Mongolia, China. This is the first report of the family Dysoneuridae in China, enhancing the geographical distribution of this family and providing reference to the paleogeography. New specimens show that the species previously classified as Dysoneuridae from the compression fossils and Myanmar amber belong to different families based on the characters of wing, ocelli and antennae; and support that the caddisflies in Myanmar amber be elevated to two families, Burmapsychidae and Cretapsychidae.
