Papiliontina machaon Shcherbakov , sp.n.

Figs 7, 11.

MATERIAL. Holotype forewing PIN 2555 /2314±; Dzhailoucho (Madygen, northern area), Leilek District , Batken Region, SW Kyrgyzstan; Madygen Formation, Ladinian–Carnian.

DESCRIPTION. Forewing 41 mm long, 17 mm wide (√LW = 26.4 mm). At least 3 weak oblique veins in costal area; slanting postnodal R branch arising just beyond nodus. R forked 3/4 way from basal cell to nodal line. Basal cell closed with X-junction of M and CuA. MP stem longer than MA stem. Nodal m-cu connecting MP and CuA stems before

their forks. Clavus acuminate at apex. Forewing unevenly darkened, more so in posterior and discal areas, without distinct dark pattern.

COMPARISON. Similar to P. spectans sp.n. in the MP stem longer than MA stem, distal R bifurcation, and the clavus not truncate, but differs from it and the type species in the nodal m-cu joining MP stem and the absence of the ocellate spot .

ETYMOLOGY. After the type species of the genus Papilio .
