Characters of a new species of the Cretaceous genus † Loeblitoides affirm affinities to the extant ' Syndicus group' of Stenichnini (Coleoptera: Staphylinidae: Scydmaeninae)

A new species of Cenomanian Stenichnini is described, based on an inclusion in Myanmar amber: dagger Loeblitoides latus sp. nov. As a close relationship between dagger Loeblitoides and the extant genera Syndicus Motschulsky, Loeblites Franz, and Horaeomorphus Schaufuss was postulated, we used 3D visualization techniques based on micro-computed tomography to search for otherwise impossible to observe morphological details and find arguments supporting this hypothesis. A novel structure, a pair of basal elytral foveae connected in a peculiar way, found in dagger L. L. latus, , indeed supports the previous views, as it is unique for the extant ' Syndicus group'. The diagnosis of dagger Loeblitoides is emended to include new findings.
