A new genus and tribe of Cretaceous net-winged beetles from Burmese amber (Coleoptera: Elateroidea: Lycidae)

With over 4,600 species distributed worldwide, the net-winged beetles belong among the most speciose elateroid lineages. Despite this, beetles of the family Lycidae are rare in the fossil record. A new genus and species of Lycidae, Cretolycus praecursor gen. et sp. nov., is herein described based on a single specimen preserved in mid-Cretaceous Burmese amber. Cretolycus praecursor represents the second known lycid from the Mesozoic. A new tribe, Cretolycini trib. nov., is erected for the species, characterised by 11-segmented filiform antennae, 3-segmented labial palpi with an enlarged apical palpomere, and elytra without costae. A catalogue of fossil net-winged beetles is appended.
