The oldest Cenozoic passandrid (Coleoptera: Cucujoidea: Passandridae) from the Paleocene of Menat (France)

The new oldest representative of the subfamily Passandrinae (Passandridae) was found in materials from Menat (Puy-de-Dôme, France). It was preliminarily assigned to the genus Passandra Dalman in Schönherr, 1817, although the new species (?) Passandra plenaria sp. n., in contrast to other congeners,...

Summary:The new oldest representative of the subfamily Passandrinae (Passandridae) was found in materials from Menat (Puy-de-Dôme, France). It was preliminarily assigned to the genus Passandra Dalman in Schönherr, 1817, although the new species (?) Passandra plenaria sp. n., in contrast to other congeners, demonstrates an exposed labrum and an absence of preapical groove or impression on the hypopygidum. Some notes on fossil records and classification of the family Passandridae are made. The distinctiveness of the families Passandridae and Laemophloeidae in light of the new data on fossils is considered, and the attribution of Mesopassandra Jin, Ślipiński, Zhou and Pang, 2019 (type genus of Mesopassandrinae) to the family Passandridae is regarded as problematic. Le nouveau représentant le plus ancien de la sous-famille Passandrinae (Passandridae) est décrit du Paléocène de Menat (Puy-de-Dôme, France). Il est attribué de manière préliminaire au genre Passandra Dalman in Schönherr, 1817, bien que la nouvelle espèce (?) Passandra plenaria sp. n., contrairement à ses congénères, possède un labrum exposé, mais n’ait, ni sillon préapical, ni impression hypopygidale. Le registre fossile et la classification des Passandridae sont discutés. La séparation entre les deux familles Passandridae et Laemophloeidae à la lumière des nouvelles données sur les fossiles est discutée. L’attribution de Mesopassandra Jin, Ślipiński, Zhou et Pang, 2019 (genre type des Mesopassandrinae) aux Passandridae est considérée comme problématique.
