Abstract.
The oldest terrestrial darkling beetle of the opatrine lineage, Palaeosclerum pohli gen. et sp. nov. (subfamily Tenebrioninae) is described from the Middle Paleocene of Menat (France). The complex of characters, combining the peculiar shape of body (robust, adapted to a fossorial lifestyle), structure of fossorial protibia, 5-segmented antennal club demonstrates a considerable similarity of the new genus to the extant representatives of the "sclerina" generic group of the subtribe Opatrina. Palaeosclerum gen. nov. is compared with recent genera Sclerum Dejean, 1834, Platynosum Mulsant and Rey, 1859 and Eurycaulus Fairmaire, 1868.
