Cretopiesma , new genus

DIAGNOSIS: Distinguished from all other genera of piesmatids, Recent and extinct, by the following features: clypeus long, protruding, with a prominent median carina that extends to middle of frons; lack of ‘‘jugal’’ appendices/lobes; rostrum about as long as head, inserted far from clypeal apex, enclosed by bucculae at base; pronotum with pair of paramedian carinae, posterior margin slightly concave; mesoscutellum very large (length 0.21X the body length); coxae of each pair widely separated; corium venation distinctive, where veins Sc, R+M, and Cu are not fused in a vein that runs parallel and proximal to the margin of the membrane and corium, instead with two transverse veins; membrane without ‘‘sutural area’’.

TYPE SPECIES: Cretopiesma suukyiae , new species .

ETYMOLOGY: From Piesma , the type genus of the family; and from the Latin creta, meaning ‘‘white earth’’ or ‘‘chalk’’, which refers to deep, chalky deposits in England that originally defined the Cretaceous Period (145–65 mya) .
