The exoskeleton ranges from dull to glossy. It is black in colour and is pitted throughout. Male specimens have an obvious depression on the head behind the large mandibles. The head is widest behind the eyes. Setae on the elytra are small. Male mandibles are large and curved with an obvious mid dorsal horizontal tooth

What it does
Larvae are presumed to eat the decaying logs in which they build galleries. Adults of this species have not been recorded feeding, but other Geodorcus species are known to feed on the sap of trees from their mouthpart anatomy.
