In Lohmann's original circumscription of the Epiprocta he also included the Tarsophlebiidae in it but Rehn (2003) placed it among the Zygoptera. Cladogram of Epiprocta after Rehn et al. 2003: Epiproctophora is used as the clade containing all odonatans living and extinct more closely related to living epiproctans than to damselflies.
