Dorcus rectus, the little stag beetle, is a species of beetles in the family Lucanidae. It can be found in China(Liaoning), Korea, Japan, Russia.[2][3] These beetles have a distinctive red shell that separates them from Dorcus curvidens. Males of this species have been observed to have mandible trimorphism,[1] a characteristic that has only been described in two species of Lucanidae—with the other one being Odontolabis cuvera—"and a small number of other invertebrates" as of 2017.[4] The mandibles are used by males as weapons.[4]
