genus: ORYCTES
species: boas  Fabricius 1775
origin: Ethiopia, Bedele leg. Petr Malec(4/2002); Zambia, Kabwe leg. Petr Malec(2/2005)
wild imago size: to 50 mm
sexual dimorphism: males with single horn
note: Common dynastid species found all over tropical Africa. Larvae develop in rotten cow mulch. I haven`t reach oviposition either with wild collected adults or captive hatched beetles. According my colleagues breeding in first generation is not complicated.
