The Family Orthophlebiidae ranges from the Middle Triassic to the Early Cretaceous. The Wealden Mecoptera have added to our knowledge of the Mecoptera from the Early Cretaceous of southern England, but have been comparatively little studied. Here we present the description of the first orthophlebiid from the Wealden of England. Mesopanorpa brooksorum sp. nov. from England is the earliest Cretaceous representative of this genus.
