Macrocoma is closely related to the African genus Pseudocolaspis, and has sometimes been treated as a junior synonym of it historically. The two genera are distinguished by the exposure of the pygidium and the shape of the anterior edges of the prosternum: in Macrocoma, the pygidium is covered by the elytra and the anterior edges of the prosternum are flat, while in Pseudocolaspis, the pygidium is more than half-exposed and the anterior edges of the prosternum are convex.[2] Currently, several species are not arranged according to these characters.[8]
