Papiliontina spectans Shcherbakov , sp.n.

Figs 5–6, 10.

MATERIAL. Holotype forewing PIN 2555 /2137± (very base and apex and most of clavus missing); Dzhailoucho (Madygen, northern area), Leilek District , Batken Region, SW Kyrgyzstan; Madygen Formation, Ladinian–Carnian.

DESCRIPTION. Forewing 38 mm long, 21 mm wide as preserved, reconstructed length ~ 42 mm and width ~ 23 mm (√LW ~ 31 mm). At least 3 weak oblique veins in costal area; slanting postnodal R branch arising just beyond nodus. R forked just before nodal line. Basal cell closed with very short arculus. MP stem longer than MA stem. Nodal m-cu connecting MP2 near base and CuA stem before fork. Clavus acute at apex. Prenodal part dark, anterior margin mostly light, postnodal part with dark apical band and ocellate spot; the eyespot with dark and inner light rings developed only on outer side, and inner light ring with extension up to RA; dark central part stretching from MA2 up to MP2, in inner half with 7 light flecks in two transverse rows.

COMPARISON. Differs from the type species in the longer MP stem, more distal R bifurcation, acute apex of the clavus, and the colour pattern, including the structure of ocellate spot .

ETYMOLOGY. Latin spectans (watching).
