Abstract
An auger beetle, Poinarinius burmaensis gen. et sp. nov. of the subfamily Dinoderinae (Bostrichidae) is described from Cretaceous Burmese amber. The new genus differs from other genera of this subfamily by the concave anterior margin of the pronotum, head visible from above and wider than the anterior margin of the pronotum, elongate and widely separated procoxae, antennae with 9 antennomeres, and body covered with long erect setae. It is distinguished from the genus Stephanopachys Waterhouse, 1888 by the transverse antennal club, protibiae with teeth, long tarsomeres 1–3, and elytra with a lobate convexity behind the middle. This is first record of the subfamily Dinoderinae (Bostrichidae) in Burmese amber.
