(Figs 1–5) Type material. Holotype : male, Longcanggou, 1500 m , Yingjing county , Sichuan Prov., 22–30.vii.2015 , Leg. Min Wang. Three paratypes : 1 male and 1 female , with the same data as the holotype; 1 male , Nanling , Guangdong Prov., Leg. Min Wang. Diagnosis. The new species resembles Meganola seima László, Ronkay & Ronkay, 2014 (Figs 6–8). Both of these species can be distinguished by the postmedial line and the medial fascia of forewing and the male genitalia. In the new species, the postmedial line is relatively broad, distinct and straight to inner margin below vein M 2 , the medial fascia is blackish brown, while in M. seima the postmedial line is thin, feeble and arched below vein M 2 , the medial fascia is brown with black. In the male genitalia, the new species has a clavate and distally arched uncus, a relatively short and widened valva, a relatively short harpe, while M. seima has a tapering and distally sharped uncus, an elongate and relatively slender valva, a long harpe. Description. Adult (Figs 1 & 4). Wingspan 20–22 mm . Head white; antenna brown, bipectinate in male, filiform in female; labial palpus short, with pale greyish brown scales. Thorax brown. Collar pale greyish brown. Abdomen bronze. Forewing ground color pale greyish brown, costal margin area brown from wing base to the postmedial line, medial fascia blackish brown, terminal area greyish brown; basal line absent; antemedial line blackish brown, arched; medial line poorly discernible; postmedial line blackish brown, arcuate above vein M 2 , straight to inner margin below vein M 2 ; subterminal line grayish brown, wavy; cilia grayish brown. Hindwing more or less greyish brown; cilia greyish brown. Male genitalia. (Figs 2 & 3). Uncus clavate, arched at apex, longer than harpe; tegumen thin, medium long; valva relatively short, shrink medially; costal margin slightly sclerotized, humped at basal part; sacculus narrow; harpe sclerotized, curved, tapering, widened basally, round at apex; saccus V-shaped. Aedeagus cylindrical, medium long; vesica without cornuti. Female genitalia. (Fig. 5). Papillae anales moderate; apophysis posterioris slender, longer than apophysis anterioris; apophysis anterioris short; ostium bursae slightly sclerotized, U-shaped; ductus bursae membranous, relatively short, about 2.3 times as long as apophysis posterioris; corpus bursae similarly oval-shaped, membranous, with a narrow and lengthways signum band and a spinule on it. Distribution. China ( Sichuan , Guangdong ). Etymology. The specific name is derived from the species M. seima .
