Abstract
Abstract. 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.
期刊介绍：
Fossil Record (FR) is the palaeontological journal of the Museum für Naturkunde Berlin. This journal was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe and appears with two issues each year. Fossil Record publishes original papers in all areas of palaeontology including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates.
