Three new species of the genus Orthocis Casey, 1898 (Coleoptera: Ciidae) from Eocene Danish amber
Three new species, Orthocis kompantsevi sp. nov., O. vilhelmseni sp. nov. and O. larssoni sp. nov. are described from late Eocene Danish amber. Orthocis kompantsevi sp. nov. differs from O. linearis (J. Sahlberg, 1901) by a glabrous body, smaller body size and shorter antennomere 10. Orthocis vilhelmseni sp. nov. differs from O. kompantsevi sp. nov. in having a bristly body, a densely punctate pronotum and elytra, and longer antennomere nine. Orthocis larssoni sp. nov. differs from O. kompantsevi in larger body size, simple punctate pronotum and coarser and more densely punctate elytra. This is the first Ciidae described from the Eocene, as well as a first proxy for Auriculariaceae in the fossil record.
