Figs 1–4, 8–9, 12–13.

MATERIAL. Holotype PIN 2555 /2136, insect with one forewing and both hind wings spread (positive impression); Dzhailoucho (Madygen, northern area), Leilek District , Batken Region, SW Kyrgyzstan; Madygen Formation, Ladinian–Carnian.

DESCRIPTION. Forewing 45 mm long, 19 mm wide (√LW = 29.3 mm; different length to width ratios in the holotype forewings of three new species are not diagnostic due to rock distortion); wingspan ~ 10 cm. At least 4 weak oblique veins in costal area; slanting postnodal R branch arising well beyond nodus. R forked 2/3 way from basal cell to nodal line. Basal cell closed with X-junction of M and CuA. MP stem more than twice shorter than MA stem. Nodal m-cu connecting MP2 near base and CuA bifurcation. Clavus obliquely truncate at apex. Prenodal part slightly darkened, anterior margin mostly dark, postnodal part with dark apical band and ocellate spot; the eyespot with dark and inner light rings complete, and outer light ring extended up to RA; dark central part not reaching MA2 and extended posterior to MP2 , with two light flecks at MP1 and MP2 . Hind wing 29 mm long (2/3 forewing length), 22 mm wide, costal area projecting crescent-like, anterior margin with more than ten close-set hooks before coupling lobe and deeply sinuate at lobe; anal area small, CuP and Pcu rather short; membrane light with dark narrow transverse band before midlength, broader apical band, and several radial streaks arising from inner margin of apical band. Pronotum 15 mm wide, 6 mm long, convex, shield-like, transverse oval with humeral angles triangularly projecting, covered with sparse transverse wrinkles. Meso- and metanotum very short, their posterior margins bisinuate with small triangular medial projections (rudimentary meso- and metascutellum). First abdominal tergites very short (1st–3rd preserved) .

ETYMOLOGY. From Greek drakon (fabulous lizardlike animal) and mimos (imitator, actor).
