Order incertae sedis

Specimen SXMG IV 0479 and SXMG IV 0480: positive and negative imprints of a right wing (presumably forewing), basal part, posterior and distal parts missing; preserved part 12.9 mm long, 6.6 mm wide; anterior wing margin partly visible; only the very distal part of ScP visible, reaching anterior wing margin; RA very strong, emitting few anterior veinlets; RP forked shortly before the end of ScP, posteriorly pectinate, with three branches (anterior-most branch arising obliquely); area between RA and RP broad, with the broadest part 1.3 mm wide; 2–3 rows of cells in the area between RA and RP basal to second fork of RP (then, single row of cells); M neither clearly concave nor desclerotized, forked earlier than RP, with 3 (4?) preserved branches; CuA + CuPa with five strongly preserved branches; except for the RA–RP area, inter-venal areas with a single row of cells (occasionally with
