Blattulidae is an extinct family of cockroaches known from the Triassic to the Late Cretaceous. Their distinguishing characteristics include "forewing has long Sc, regular venation with distinct intercalaries and hindwing has simple CuP, branched A1."{{Cite journal|last1=WANG|first1=TIAN-TIAN|last2=LIANG|first2=JUN-HUI|last3=REN|first3=DONG|date=2007-04-09|title=Variability of Habroblattula drepanoides gen. et. sp. nov.
