Eoplaytpus jordali gen.n. et sp.n., the first described Platypodinae (Coleoptera: Curculionidae) from Baltic amber

摘要

The frst platypodine beetle from Baltic amber, Eoplatytpus jordali gen.n. et sp.n., is described from two specimens. The species sharesdiagnostic characters with Tesserocerini and a phylogeny reconstructed with morphological and DNA data groups the species with Mitosoma, Cenocephalus, and Chaetastus. The species lacks mesepisternal and mesonotal carinae and has an antennal club wider than long,which is a unique combination of generic characters. Furthermore, the species provides an additional calibration point for dating of platypodine phylogenies. It corroborates the molecular dating of the Mitosoma + Cenocephalus + Chaetastus clade at approximately 50 mya.Finally, the rarity of platypodine Baltic amber inclusions is discussed.
