Occurrence in Corsica of a thermophilous Coleoptera belonging to the “Canthydrus diophthalmus” species-­complex in the Middle Holocene, possible witness of a climate optimum at c. 6 500 yrs BP (Cavallo island, Corse-du-Sud, France)

The discovery of subfossil fragments of Canthydrus Sharp, 1882 (Coleoptera, Noteridae) in Holocene sediments (c. 6 500 yrs BP) from the coastal retrodunal Greco pond, on Cavallo island (Lavezzi archipelago, Corse-du-Sud, France), is the first French citation for this thermophilous water beetle genus. This discovery raises issues about the factors that led to the probable extinction of this taxon at a local scale.
