On the Nosodendridae from mid-Cretaceous amber of northern Myanmar (Coleoptera: Nosodendroidea).

Nosodendridae is a small polyphagan beetle family with a sparse fossil record. Herein, the fossil Nosodendridae from mid-Cretaceous Burmese amber (ca. 99 Ma) are systematically reviewed. Nosodendron cretaceum Deng et al. is transferred into Archaenosodendron Li Cai gen. nov., as A. cretaceum (Deng et al.) comb. nov., primarily based on the morphology of prosternum. Three new species of Archaenosodendron from Burmese amber, A. explanatum Li Cai sp. nov., A. remotidens Li Cai sp. nov., and A. angulare Li Cai sp. nov., are also described and illustrated. A key to nosodendrid genera and species from Burmese amber is provided.
