New Archostemata (Insecta: Coleoptera) from the French Paleocene and Early Eocene, with a note on the composition of the suborder

The paper deals with descriptions of four new species of Archostemata from the Paleocene and Earliest Eocene amber, Cupes manifestus n. sp., C. orbiculatus n. sp., C. ponomarenkoi n. sp. and Micromalthus eocenicus n. sp., the latter representing the oldest member of genus Micromalthus Leconte 1878 (Micromalthidae). The position, composition and origin of the genera Cupes and Micromalthus are considered. Cupes seemed to appear during Cretaceous or very close to this period, while Micromalthus could originate somewhat later. The synonymy of Cupedini and Priacmini is grounded. The genus Crowsoniella Pace 1975 (Crowsoniellidae) could be excluded from the suborder Archostemata and transferred into the infraorder Cucujiformia (Polyphaga).
