A new genus and species of cucujoid beetle, Pleuroceratos burmiticus Poinar and Kirejtshuk in the Oryzaephilus generic complex of Silvanidae, is described from Early Cretaceous Burmese amber. The new genus is characterized by the head, pronotum and elytra bearing a series of longitudinal costae, large, protruding round eyes, long tri-quadri-dentate mandibles, elongate trochanters, contiguous procoxae, 11- segmented antenna with 3-segmented symmetrical, abrupt, loose club bearing a sensory extension on apical segment, 5 subequal, freely movable, abdominal segments, and elytra covering most of the abdomen. This is the first description of a Mesozoic member of the family Silvanidae.
