Like all Dynastinae species, these beetles are strong flyers, although they never cover long distances during the flight. The body is dark brown, while the ventral part of the body is black and brilliant and the front legs are unusually long.

Their eyes may be white or red and are adapted to low light levels, as this species is nocturnal. In addition to their impressive and ornate protuberance they also have a smaller thoracic horn, also forked. By means of their forked horn they lift other males off the ground and throw them into the air. The long cephalic horn of this species has a characteristic shape in the form of the letter Y and it is used by males during the mating period and to maintain territories. The males are much larger, reaching a length of 40–80 mm, while females can reach a length of about 40–60 mm. Mounted specimen Allomyrina dichotoma male from TaiwanĪllomyrina dichotoma shows a striking sexual dimorphism.
