Abstract
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.
期刊介绍：
Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings.
Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale.
Research Areas include:
• Regional geology
• Stratigraphy and palaeontology
• Palaeobiology
• Palaeobiogeography
• Palaeoceanography
• Palaeoclimatology
• Evolutionary Palaeoecology
• Geochronology
• Global events.
