- Abstract
Based on a well-preserved specimen from Eocene Baltic amber, a new weevil – Baltacalles triumurbium gen. et sp. nov. – is described and illustrated. The new fossil genus is similar to the extant Acalles Schoenherr, 1825 but differs from it in the denticulate femora, abdominal ventrites 1–2 combined about 2.8 times as long as ventrites 3–4 combined, distinct scutellum, narrow, subparallel metepisternum, not flattened rostrum, and narrow forehead. This is the first described representative of the Tylodina (Molytinae: Cryptorhynchini) described from Baltic amber. The data on the geographically and stratigraphically distinct local sources of Baltic amber in the Kaliningrad Region are provided; the main sampling localities are listed and photographed. The importance of the possible exact labeling of the material is emphasized.
