Blapsium is an extinct genus of beetles from the Middle Jurassic of England.[1][2] The only described species is B. egertoni,[3] which is known from a single specimen found by the Earl of Enniskillen at the Taynton Limestone Formation, also known as the Stonesfield Slate.[4] The specimen is deposited in the Natural History Museum, London. It is incompletely preserved, lacking a head, pronotum and legs. It has a broad, convex body. It has a very short metathorax, which may suggest that it was apterous.[1][5]

In his original description of the genus, John O. Westwood compared Blapsium to the darkling beetles and ground beetles.[3] Ponomarenko (2006) redescribed the holotype of B. egertoni and referred it to the tribe Notocupedini in the family Ommatidae (considered in the paper to be a subfamily of Cupedidae), which was followed by Kirejtshuk (2020).[1][5]
