numerous small dark transverse strigulae, posterior half with three
or four marginal streaks alternating with minute transverse marks
and slightly edged below with yellow; this color becoming deeper,
tawny orange posteriorly and forming a well-defined streak below
posterior part of costa and just before apex, halfway to vein 7; a
faint dark suffusion on base of dorsum; a well-defined roundish patch
of dark fuscous irroration on middle of dorsum, reaching to upper
edge of cell,
slightly extended basad along its lower edge; a more or
less defined wedge-shaped patch of dark fuscous irroration before
termen, from below costa almost to tornus, interrupted in its middle
by yellow suffusion along veins; a circular jet-black spot above middle
and against posterior edge of last mentioned patch, containing an
oval pale blue metallic dot towards its lower edge; edge of termen
narrowly fuscous, interrupted between veins, preceded by light yellow,
before these a thick slightly raised shining silvery-leaden streak parallel
to and before edge of wing, from end of vein 9 to that of vein 4.
Cilia pale yellow, a leaden-grey band from apex to 3/4 of termen,
cilia beyond this band irrorated and slightly mixed with dark leaden
grey.
Hindwing rather dark brownish fuscous with some yellowish tinge,
cilia brownish fuscous with pale yellow base and a darker subbasal
band, beyond this band and between ends of veins 6 to 3, cilia pale
yellow, narrowly barred with fuscous opposite these veins.
Male genitalia: Tegumen triangular, strongly down-curved. Uncus
rather rounded and thickened, long-haired in middle, bifid, halves
beak-shaped (broader than in hybristis). Socii absent. Gnathos
strong but arms rather narrow, wide; hood represented by a curved,
denticulate horizontal rod. Vinculum large, elongate (shorter than
in hybristis). Transtilla membranous, ill defined, inverted trapezoidal.
Diaphragma forming a thickened transverse ridge, trapezoidal,
with a granulate structure. Valva long and narrow, simple,
concave lengthwise; costa slightly modified and a little thickened,
3/4, sacculus moderate, under 1/2; cucullus radially wrinkled with
two long thorns on lower edge. Aedeagus moderate and rather
slender, gradually dilated basad and with a rounded base, top obliquely
truncate.
Cornuti, a sheaf of not numerous long and slender spines,
undulate at their bases, and a fasciate patch of dense fine spines.
Female, neallotype, 20 mm.
Fore- and hindwings slightly narrower
than in male. Shining scaling on forehead less extended. Fuscous
suffusion of forewing more extended, transverse strigulae beyond cell
darker, continuous. Otherwise in all respects, also in the length of
palpi, similar to the male.
Female genitalia: Lobi anales slender and elongate. Sterigma inverted
trapeziodal, laterally ill defined; lamella post vaginalis, a simple
