New genus and species of Lamprosomatinae (Coleoptera: Chrysomelidae) from Eocene Baltic amber

[摘要] Fossil records of Lamprosomatinae (Coleoptera: Chrysomelidae) are scarce. Till now only three findings of this subfamily were reported and all originated from Eocene Baltic amber. Based on well-preserved specimen, Damzenius anitae gen. et sp. nov. is described and illustrated from this Lagerstätte. A key to the known extinct species of Lamprosomatinae is provided. Assumed minimum age of Lamprosomatinae is dated as mid-Eocene to Upper Eocene (47.8-33.9 Ma). The diverse fossil Lamprosomatinae representatives provide strong evidence for the presence of thermophilic, humid and mixed forest, and indicative of warm temperate, humid, equable climate with reduced thermal seasonality in the Eocene Europe.
