Blattoidea

Cretaceous predatory roach Raphidiomimula burmitica, from Grimaldi & Ross (2004).


Belongs within: Dictyoptera.
Contains: Mantodea, Isoptera, Blattaria.

The cockroach superfamily Blattoidea, as used by Vršanský et al. (2002), is paraphyletic to Polyphagoidea, Mantodea and Isoptera, and hence includes all crown-group dictyopterans and some related fossil families. These include the Raphidiomimidae, a Late Jurassic to Cretaceous group of predatory roaches with long slender legs, of which the front pair are raptorial (Grimaldi & Ross 2004). They also include the Upper Jurassic Skok svaba, which exhibited adaptations for jumping (Bohn et al. 2010).

Synapomorphies (from Vršanský et al. 2002): Ovipositor very short externally; eggs laid in two-row packages (in crown taxa at least); size small (body length under 20 mm, fore wing about 8-15 mm); fore wing elongate, with fore and hind margins parallel.
