Detailed view

"Heavily scaled (? hind) wing. R1 forked at apex, Rs forked, probably with third fork, although origins obscure. Three median veins, obscure towards base. Cu clearly divided. 1A and 2A probably joined; tip of 3A and rest of anal area indistinct. Scales 0.20-0.23 mm long, 0.06-0.08 mm wide. Strongly ridged, ridges vary in width, according to the width of scales, usually 0.002 mm apart. Cross-ribs mostly absent, although some lateral connections between the longitudinal ridges are apparent near base of some scales. Apex of scales smoothly rounded. Two, possibly more, different types of scales. Marginal scales thinner, some thinner scales mixed in with thicker ones on wing membrane. The wing margin has longer scales along the hind margin and probably had a substantial fringe of scales. Fewer ridges on some scales, 12-13 as against 18-22 on others. The ridges on the scales as seen in the stereoscan micrographs (Fig. 58d) are considered to represent the infilling between the original ridges (striae) and their compression, with the dark lines representing the ridges from the original scale. The scales shown in the micrographs are the narrow ones with fewer striae." (Whalley 1985).


No other lepidopterous remnants are known so far from the Sinemurian age. Detailed information see under Archaeolepidae.
