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

Abstract

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.
