New ichnotaxon Megascolytinus zherikhini (Coleoptera: Curculionidae: Scolytinae) from upper cretaceous deposits of mongolia

Gallery systems of Scolytinae on a petrified Araucaria trunk fragment from the Late Cretaceous of Gobi, Mongolia, similar to those of extant members of the supertribe Hylesininae, but exceptionally large (esti mated body length of the beetle about 20 mm), are described as a new ichnotaxon, Megascolytinus zheriknini
