Similar species
There are some species that resemble M. hagenii . Micrathyria didyma , Micrathyria aequalis and Pachydiplax longipennis are somewhat smaller and have a more distinctive chest mark. The slightly larger Dythemis velox and Dythemis nigrescens , on the other hand, can be differentiated by the points on the wing tips. Emetic Morhoga mendax is significantly larger and therefore easy to distinguish. It is more difficult to distinguish the females from Erythrodiplax berenice , which can be done via the ovipositor , which is more developed in this species .
