Diagnosis. This species is similar to Meganola mediofascia (Inoue) , but can be distinguished by the elongated, ovoid, dark brown costal patch, and inner edge of medial band angled medially and more narrow; male genitalia with pseudouncus thumb-shaped, bulbous valva, with basal appendix lobe; horn-shaped harpe, saccus U-shape; aedeagus relatively short and thick; female genitalia with the ostium bursae tubular with cervix bursae; and corpus bursae relatively large with a thorn-shaped signum and no horizontal broad band-shaped signa.

In M. mediofascia (Inoue) , antemedial line not arcuate, outer edge of medial band relatively more angled. In male genitalia, Pseudouncus ovoid, weakly covered with setae on dorsal side; weakly sclerotized a pair of arms in basal area of pseudouncus, which arms covered with thin spines. Valva not bulbous with hairy basal area; fingershaped harpe with dentated; saccus V-shape; aedeagus relatively long and slender. In female genitalia, ostium bursae weakly sclerotized funnel-shaped without cervix bursae, corpus bursae with two triangular signa and horizontal band-shaped signa.

Description. Adult ( Figs 11a, b ). Wingspan 16–19 mm in both sexes. Frons white, with brownish scales on lower position. Labial palpi dark brown, with white scales on dorsal area. Thorax white, with irrorate brown tip. Forewing ground color of male pale gray, paler in female, with an elongated, ovoid, dark brown costal patch in to one-forth from basal; two black tufts on subcostal line between antemedial to medial area; black median band with slightly arcuate outer edge in discal area; dark brown subterminal line waved three times; dark brown series of terminal patches rectangular; cilia gray. Hindwing ground color gray; cilia gray. Abdomen gray in both sexes. Male genitalia ( Fig 22 ). Pseudouncus thumb-shaped, hairy, half-length of tegumen. Tegumen bell-shaped, with one-third from basal area tumescent. Valva stout, with rounded apex; costal margin sclerotized, gently curved inwardly; basal appendix lobe of valva rectangular. Sacculus bulged, membranous. Harpe horn-shaped, apex blunt, especially enlarged basal area. Saccus broadly blunt, V-shaped. Aedeagus stout syringe-shaped, without cornutus. Female genitalia ( Fig 34 ). Papillae anales weakly sclerotized. Apophyses posteriores almost 1.5 times longer than anteriores. Ostium bursae membranous, straight, tubular. Ductus bursae membranous, tubular, broaden near corpus bursae. Cervix bursae present. Corpus bursae large, ovoid, with a thorn-shaped signum.

Distribution. Korea (GG, JJ).

Hostplants. Unknown.

Remarks. This new species named for the unpublished Oh (1991) name.

László et al. (2015) and Kim et al. (2016) erroneously listed this unpublished species from Dr. Oh’s Ph.D Thesis. In this study, we formally report M. parki from Jeju Island.

Etymology. This species name is dedicated with gratitude to Prof. Kyu-Tek Park, one of the most famous Korean lepidopterist.
