The ground beetle genus Bembidion Latreille in Baltic amber: Review of preserved specimens and first 3D reconstruction of endophallic structures using X-ray microscopy (Coleoptera, Carabidae, Bembidiini).

ABSTRACT: The ground beetle genus Bembidion is a highly diverse group of small predators with more than 1.200 described extant species. In contrast, only two representatives of Bembidion are known from the amber fossil record and their position within this mega-diverse genus is dubious. Here, we address the taxonomic position of these two extinct Bembidion species (B. succini Giebel, 1856 and B. christelae Ortuño & Arillo, 2010). Based on the insufficient description and the missing type specimen, B. succini, nomen dubium, cannot be assigned to the genus Bembidion and/or to the tribe Bembidiini with certainty. The subgenus Archaeophilochthus Ortuño & Arillo, 2010 was erected for the second extinct species, B. christelae, based on external chara
