Diagnosis.
The new species resembles
Meganola ohsunghwani
László, Ronkay & Ronkay, 2014
(Figs 12–14). Externally, the new species has an arched postmedial line between vein Cu
2
and vein A, while
M. ohsunghwani
has a straight postmedial line between vein Cu
2
and vein A. In the male genitalia, the differences of configuration are obvious: in the new species, uncus is elongate at basal part and 2/3 time as long as saccus; valva is relatively slender and widened basally; the dentations of harpe are small and short; saccus is short; cornutus is straight. In
M. ohsunghwani
uncus is short at basal part and 1/3 time as long as saccus; valva is relatively broad and narrow basally; the dentations of harpe are long; saccus relatively broad and long; cornutus is curved.
Description.
Adult (Fig. 9). Wingspan
20 mm
. Head greyish white; antenna brown, bipectinate in male; labial palpus brown. Thorax darker brown. Collar greyish white. Abdomen brown. Forewing ground color pale greyish brown, costal margin area blackish brown, terminal area brown; basal and antemedial lines poorly discernible; medial line feeble, wavy; postmedial line blackish brown, represented with dots above vein Cu
2
and a wavy line below vein Cu
2
; subterminal line darker brown, wavy. Hindwing more or less greyish brown.
Male genitalia.
(Figs 10 & 11). Uncus stripe-shaped basally, leaf-shaped distally, sharped at apex, shorter than saccus; tegumen thin, medium long; valva slender, broad basally; costal margin slightly sclerotized; sacculus small; harpe sclerotized, distally upcurved, with dentations at costal margin; saccus relatively slender, V-shaped. Aedeagus cylindrical, slender and curved; cornutus clavate, flake-shaped apically, 3/8 time as long as aedeagus.
