摘要：
The new oldest representative of the subfamily Sagrinae, Gallopsis perita gen. et sp. n. from the Paleocene of Menat (France), is described and illustrated. It is distinguished from the genus Neodiaphanops Blackburn, 1899 by the metafemora without teeth, wider pronotum, weakly widened tibiae, bilobed tarsomere 2, subparallel elytra, and narrower metanepisterna. It differs from the Australian genus Carpophagus Macleay, 1826 in the head without rostrum, weakly widened metafemora without teeth, and gently sculptured pronotum and elytra. The new genus differs from the Eocene genus Eosagra Haupt, 1950 in the longer antennomere 2, wider pronotum and elytra, dense and diffuse elytral puncturation, and weakly inflated metafemora.
