Short summary
Palaeatalasis monrosi gen. at sp. nov. belonging to the subfamily Sagrinae (Chrysomelidae) is described from the Green River Formation (age 53.5–48.5 Ma). The new genus is similar to Atalasis Lacordaire, 1845 from Argentina. It also differs from the Eocene Eosagra Haupt, 1950 and the Paleocene Gallopsis Legalov, Kirejtshuk et Nel, 2019. It is the first record of the Sagrinae from North America and the fourth known species of the family Chrysomelidae from the Green River.
