Figs. 1–2

Diagnosis. As for the genus. Forewing board, MP forking beyond the separation of MA from Rs.

Description. Only forewing preserved. Forewing board, the apex missing; 9.4mm wide. Forewing covered with fuscous markings, forming 7 distinct hyaline fenestrated spots and some fragmentary small fenestrated spots on the margin. Trichosors present in posterior margin, and partly close to the wing apex in anterior margin. Pterostigma fuscous. sc-r cross-vein not preserved, only 2 cross-veins between R and Rs due to poor preservation. Rs branches numerous, cross-veins arranged irregularly. Cu forked at the base, Cu2 with many pectinated branches. A1 forming numerous branches, and A2 also with many distal branches.

Holotype. CNU-NN99032. Only the forewing preserved with the apex damaged.

Occurrence. Jiulongshan Formation, the Middle Jurassic, Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China.

Etymology. The name of the new species refers to the distinct large fenestrated spots on wings, which is the combination of the Latin septem (meaning “seven”) and maculatus (meaning “spots”).
