Comment. Among Tertiary amber genera (and species) of handsome fungus beetles, only Discolomopsis dominicana (Anamorphidae) from mid-Miocene Dominican amber (not included in the key) is known/ described from outside Eocene European amber.
New handsome fungus beetles (Coleoptera: Coccinelloidea: Anamorphidae, Endomychidae) from European amber of the Upper Eocene
Plain Language Abstract
This work describes eight new species of handsome fungus beetles in Baltic and Bitterfeld ambers (Eocene, 55–34 million years old). The beetles belong to five genera that are new to science and two Recent genera. The paper also contains the determination key all currently described handsome fungus beetles in Eocene amber.
