E–F, 4A–B)
Diagnosis.
Body relatively small sized. Forewing: Rs stem originated from R1 distant to the wing base; separation of MA from Rs distant to base.
Description.
Head deformed, eyes protruded; antenna filiform, scape inflated, flagellum not beyond the forewing as preserved. Thorax. Prothorax short; meso- and metathorax with well developed sclerite.
Abdomen with 9 visible segments as preserved, while the recent species generally have 10 segmented abdomen. The caudal segment preserved poorly, approximately coniform.

length,

width. Forewing hyaline; pterostigma light colored; nygmata and trichosors undetected because of poor preservation; cross-veins r1-rs edged with fuscous spots in base; costal cross-veins simple, with few distal forks; area between Sc and R1 slightly broadened close to the wing base; six cross-veins r1-rs (right forewing); separation of Rs from R1 distant to the base; MP forks close to the separation of MA from Rs, distant to the wing base; MP field with 3 cross-veins, MP2 with well defined distal dichotomies; Cu forked at base; CuA long, pectinately branched distally; CuP shorter than CuA, with 4 distal pectinately branches; A1 well developed, the length exceeding half of CuP; A2 and A3 not preserved. Hindwing hyaline, without any marks; costal field narrow; Rs with 12 branches.
