DIAGNOSIS. — The same as for the monotypic genus.
MATERIAL. — Holotype, NIGP163538 a, b, part and counterpart of a well-preserved forewing, with posterior wing base and middle-distal wing half preserved (Fig. 2); deposited in NIGPAS.
TYPE LOCALITY AND STRATUM. — Qingyun Town, Yulin City, Shaanxi Province, NW China; Yanan Formation, early Middle Jurassic (c. 174-172 Ma, Aalenian; Zhang et al. 2021).
ETYMOLOGY. — The specific name is after Qingyun Town, main locality in the area where the specimen was found.
DESCRIPTION
Specimen NIGP163538a, b (Figs 2; 3), middle-distal wing part of wing 41.7 mm long, width at level of N 14.4 mm; distance from wing base to Arc 6.6 mm, and from N to Pt 18.8 mm. Median area free of crossveins. CuP strong, separating submedian and subdiscoidal areas at 0.7 mm basal of Arc. DC open. Subdiscoidal area broad and transverse, free of crossveins. CuA separated from MP 9.3 mm from wing base, aligned with MAb basally. Area between CuAa and MP with one row of cells basally, and as wide as postdiscoidal area, 1.9 mm wide, distinctly narrowing distally and very broad in most distal part; CuAa with 1-3 rows of cell between it and posterior wing margin in basal area. MP sigmoidally curved. MAa slightly curved, more or less parallel with MP distal of level of N; postdiscoidal area with one row of large cells basally, expanded distally with two or three cells before N, narrower distally with one row of cells below N, and two rows distally. No secondary antenodal crossveins present between C and ScP near N; three secondary antenodal crossveins present between ScP and RA distal of A×2. Fourteen postnodal crossveins present between C and RA, not aligned with nineteen postsubnodal crossveins between RA and RP1 basal of Pt. Seven antesubnodal crossveins present in distal part of area. Seven postnodal crossveins present distal of Pt. Bqr space between RP, RP2, IR2 and oblique vein ‘O’ very long and narrow, with one row of cells and 15 crossveins preserved. Single oblique vein ‘O’ present, seven cells and 5.8 mm distal of RP2 base. RP2 curved. Nodal structures well preserved; Sn oblique and well aligned with Cr and RP2. IR1 originating seven cells and 5.5 mm distal of RP2 base; IR1 weakly zigzagged basally, more or less parallel to RP1. Pt not braced, long and narrow, sclerotized, 7.7 mm long and 0.8 mm wide. Area between MAa and RP3/4 widened distally, with many cells along below Pt. Area between RP3/4 and IR2 with one row of cells basal of N level, expanded distally with six rows of cells below N. Area between IR2 and RP2 with one row of cells slightly before Pt, expanded distally with 2-4 rows of cell below Pt. Area between RP2 and IR1 with one rows of cells slightly basal of Pt base, widened distally with many rows of cells. Area between IR1 and RP1 with two rows of cells before Pt, widened distally with many rows of cells. Area between RA and RP1 before Pt end, widened distally with two or three rows of cells.
