Little gem cockroach Aglaopteryx gemma, copyright Jeff Garner.

Belongs within: Blattaria.
Contains: Ischnoptera, Parcoblattini.

The Blattellidae are a diverse group of small to medium-sized, mostly fast-running cockroaches. A small number of species have become cosmopolitan domestic pests, including the German cockroach Blattella germanica and the brown-banded cockroach Supella longipalpa.

Characters (from Roth 1991): Size usually small to medium; antennae longer than half body length. Legs long, slender, spiny, ventral surfaces of tarsi spined. Tegmina and wings fully developed or with reduced wings in both sexes, sometimes with small tegmina only. In fully alate forms, hind wings with or without an apical triangle; R usually well developed, with simple, regularly spaced anterior rami; CuA unbranched (simple), or with complete branches only, or with both complete and incomplete rami. Cerci fairly long, tapering, extending well beyond body. Male abdominal terga unspecialised, or with one or two modified terga used in sexual behaviour. Male subgenital plate (S9) asymmetrical or symmetrical, usually with two styles; hooklike genital phallomere on right or left sides. Female subgenital plate broad, rounded, rarely bivalvular. Oviparous or ovoviparous.
