Cratacanthus dubius
Dubious Harp Ground Beetle
Cratacanthus dubius is a species of ground beetle in the family Carabidae, and the sole member of the genus Cratacanthus. It is a moderately-sized beetle with a distinctive harp-like pronotal shape that gives the genus its name. The species has a broad distribution across North America, with records from both Canada and the United States. Its common name reflects both its taxonomic placement in the harp ground beetle lineage and the uncertainty that surrounded its early classification.
