"Roachoids", also known as "Roachids", "Blattoids" or Eoblattodea, are members of the stem group of Dictyoptera (the group containing modern cockroaches, termites and praying mantises). They generally resemble cockroaches, but most members, unlike modern dictyopterans, have generally long external ovipositors, and are thought not to have laid ootheca like modern dictyopterans.
