Abstract
Eucnemidae is a relatively large beetle family belonging to the polyphagan superfamily Elateroidea. Numerous fossil eucnemids have been reported from Cenozoic deposits, but the Mesozoic record of Eucnemidae is much sparser. Here we describe and figure a new eucnemid beetle, Muonabuntor grandinotalis gen. et sp. nov., discovered from mid-Cretaceous Burmese amber (ca. 99 Ma). The new genus resembles extant Jenibuntor and Euryptychus in having simple hypomera and tubular antennomeres 9–11, but differs from the latter genera by its comparatively longer pronotum, weakly striate elytra, and large metacoxal plates. The fossil record and classification system of Eucnemidae are also reviewed.
