Abstract

Abstract Molecular dating estimates the appearance of the family Oedemeridae in the Early Cretaceous. Several fossil representatives are known from Spanish (105 Ma) and Myanmar (99 Ma) ambers. The family also has been mentioned by several authors to occur in Eocene Baltic amber, but virtually no species was described until now. Here, we provide a description of the first fossil oedemerid species from Eocene Baltic amber, which is classified within subfamily Oedemerinae, in the extant genusOedemeraOlivier asOedemera(s. str.)girulskiin. sp. The presence of appendiculate pretarsal claws and relatively large eyes separate the new species from its extant congeners. UUID: http://zoobank.org/24b0b919-8684-4908-b002-9521b071dcc8 .
