Very large. Body length 30-40 mm (males, without mandibles), 45-60 (males, including mandibles), females are 30-35 mm. Males are distinctive with elongated mandibles, huge size. Females are similar, but without huge mandibles. Differentiate from Lucanus capreolus by dark legs, smooth (not punctate) pronotum. Mandibles of female L. elaphus have several small teeth, just one tooth in male (and female?) L. capreoulus. Labrum (upper "lip") is triangular in Lucanus elaphus (male and female), blunt in Lucanus capreolus(male and female).
This specimen is a male. Also known as "giant stag beetle."
