Dorcus is a genus of beetles in the family Lucanidae (stag beetles). Of the 30-odd species, most occur in Asia and India; two are found in southern Europe, and two species are from North America.[1] Previously, specimens with serriform teeth on the mandibles and sable pigment were called Serrognathus whereas specimens with but a singular or multiple bulky notches on the mandibles and lustrous sable pigmentation were called Dorcus. Serrognathus was recently reclassified and merged into the genus Dorcus.[2]
