Cockroaches are members of the superorder Dictyoptera, which includes the termites and mantids, [5] a group of insects once thought to be separate from cockroaches. Currently, 4,600 species and over 460 genera are described worldwide.
Cladistic analysis of five DNA sequences in 107 species representing all the termite subfamilies, all six cockroach families, including 22 of the 29 subfamilies, and five of the 15 mantis families (as out-groups) showed that the termites are nested within the cockroaches, and that the Cryptocercidae is a sister group to the termites.
