Abstract

The fossil ship-timber beetle, Adamas hukawngensis gen. et sp.n., is described and defined based on one well preserved specimen in mid-Cretaceous amber from the Hukawng Valley in Northern Myanmar. The new species can be readily distinguished from all other extinct and recent members of the family due to the presence of a lozenge-shaped scutellum with a meso-longitudinal groove. Modifications of lymexylid metathoracic wing venation and palaeobiomigratory significance are briefly discussed.
