A new genus of lined flat bark beetles in Early Eocene amber from northern France (Coleoptera: Laemophloeidae)

A new genus and species of fossil lined flat bark beetles (Cucujoidea: Laemophloeidae) is described and figured from the lowermost Eocene (Ypresian) amber of Oise, northern France. Oisephloeus resinatus gen. & sp. n. is quite similar to the genus Lathropus Erichson but may be distinguishable by the tarsal formula and the pro- and mesocoxal cavities. Further determination awaits extensive phylogenetic analysis of the family and additional fossil data. While relationships may be obscure, Oisephloeus gen. n. nonetheless provides an important calibration point for understanding the history of Laemophloeidae.
