Figure 7. Holotype of Anglophlebia gigantea (Zeuner, 1962) (NHMUK In.51030 pt and cpt); Stonebarrow, Dorset (Sinemurian); photograph and reconstruction. AA = anterior anal; Ax1 = second branch of primary antenodal crossvein; Ax2 = third branch of primary antenodal crossvein; CuA = anterior cubitus; CuP = posterior cubitus; DC = discoidal cell; IM = intercalary medial vein; MA1 = anterior branch of anterior median; MA2 = posterior branch of anterior median; MP = posterior median; RA = anterior radius; RP = posterior radius; T = triangle.
in some Campterophlebiidae (Nel et al., 2008), or (2) that we have a forewing with some hindwing characters (as in the Liassogomphidae Tillyard, 1935 and modern Anisoptera in which the discoidal cell is divided into a hypertriangle and a discoidal triangle in the forewings, compared to the
Heterophlebiidae Handlirsch, 1906, in which this is only true in the hindwings). Either way, and although the specimen is only the basal fragment, it is unique among the British materials (checked at all known repositories of British Late Triassic– Early Jurassic material in the UK and the USA), the Liassic
