| الوصف: | A new genus, Palaeatalasis gen. nov. (type species P. monrosi sp. nov.), from the tribe Megamerini (Chrysomelidae: Sagrinae) from the early-middle Eocene Green River Formation is described and illustrated. The new genus is similar to the Recent Atalasis Lacordaire, 1845 but differs from it in the subparallel sides of the pronotum, metafemora without teeth, and non-emarginate eyes. It differs from the Eocene Eosagra Haupt, 1950 in the large, convex, non-emarginate eyes, wide elytra, and transverse pronotum. The new genus is distinguished from the Paleocene Gallopsis Legalov, Kirejtshuk et Nel, 2019 in the wide forehead and convex eyes. It is the first record of the Sagrinae from North America and the fourth known species of the family Chrysomelidae from the Green River. |
