Appearance
"Chalcosoma atlas", like other beetles of the genus "Chalcosoma", is remarkable for its size, that can reach a length of about 25–60 millimetres in the females. As common in some Scarabaeidae, the males are larger than the females, reaching a length of about 60–130 millimetres. The males have specialised horns on the head and thorax that they use to fight with each other to gain mating rights with females. The Atlas beetle differs from other "Chalcosoma" species in the end of the cephalic horn of the Atlas, which is broadened.Naming
