A new family, Worcestobiidae fam. nov., is established for two Triassic fossil species of Mecoptera removed from the family Orthophlebiidae: Orthophlebia gigantea Tillyard, 1933 and O. haradai Ueda, 1991. A new genus, Worcestobia gen. nov., is erected and both species are transferred to this genus. The new taxa were established as a result of ongoing taxonomic work on Orthophlebiidae, one of the most problematic families within fossil Mecoptera, considered to be a paraphyletic group of species.
