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
.
