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.

摘要

Nosodendridae 是一个小型多甲目甲虫家族，化石记录稀疏。本文对产自缅甸白垩纪中期琥珀（约 9900 万年前）的 Nosodendridae 化石进行了系统研究。基于胸板的形态，将白垩纪 Nosodendron cretaceum Deng et al. 归入古须甲属（Archaenosodendron），作为 A. cretaceum （Deng et al.）的组合新种。本文还描述并图示了产自缅甸琥珀的古须甲属的 3 个新种：A. explanatum Li Cai sp. nov.、A. remotidens Li Cai sp. nov. 和 A. angulare Li Cai sp. nov.。提供了缅甸琥珀中的须甲目属和种的检索表。
