Dorcus rectus, the little stag beetle, is a species of beetles in the family Lucanidae. It can be found in China(Liaoning), Korea, Japan, Taiwan and 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]
