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."[1] Due to the poor ability of forewing venation to correctly classify modern cockroaches to extensive homoplasy, the value of this family as a taxonomic unit has been strongly questioned, with some authors considering the family a nomen dubium.[2]
