摘要
Elmadulescens rugosus Peris, Maier et Sanchez-Garcia n. gen. n. sp. is described based on a single specimen from Spanish amber (El Soplao outcrop, Early Albian, Early Cretaceous). The discovery of this specimen in amber is very interesting, since aquatic beetles are not common in fossil tree resin. This fossil pushes back the oldest known specimen of Elmidae from the Eocene (similar to 40 Ma) to at least the Early Cretaceous (similar to 110 Ma). (C) 2015 Academie des sciences.
