Diagnosis. The new species is externally similar to Leuconola wilsonae (Holloway, 2003), but has a quadrangular transverse black patch at forewing costa, that is triangular in Leuconola wilsonae. According to the structure of the male genitalia, the species has no closer relationship with the genus Leuconola but belongs evidently to Meganola and its closest relative is M. tarkabarka László, Ronkay & Witt, 2010 . The new species can be distinguished from M. tarkabarka by its somewhat longer uncus, conspicuously longer harpe and more elongated basal lobe of valva.

Description. Adult ( Figs. 11, 13 ). Wingspan 15–18 mm. Head white; antenna pale brown, white at base, bipectinate in male, filiform in female; labial palpus short, dorsally white, ventrally pale brown. Thorax brown with grayish white scales. Collar white. Abdomen brown with a few white hair scales. Forewing ground color grayish white, with conspicuous black patch in and above cell; basal line is a pale brown spot; antemedial line brown, light; medial line obsolescent, represented by a few dark scales below cell; postmedial line brown, wavy; subterminal line grayish brown, broad and wavy; cilia grayish brown; terminal area mostly reddish brown. Hindwing ground color pale brown; discal spot blackish gray and small; cilia grayish brown. Male genitalia ( Fig. 12 ): Uncus thin and very long, broad at base, then tapering and pointed at tip; tegumen thin; valva divided into large, rounded basal and much smaller, slender apical part; apical section gradually dilated towards apically rounded cucullus; basal section rounded quadratic; harpe robust, elongated and strongly sclerotized, curved to ventral margin and beyond it, round at top; costa slightly humped at base; sacculus smooth; vinculum small; juxta tongue-shaped. Aedeagus short; coecum short tubular; vesica without cornutus. Female genitalia ( Fig. 14 ): Papillae anales moderate; apophysis posteriores longer than anteriores; ostium bursae arcuate, slightly sclerotized; ductus bursae membranous, as long as corpus bursae; corpus bursae ovoid, membranous with two signum plates, one of them thorn-shaped, the other falciform; appendix bursae small, pyriform.

Distribution. China (Guangdong, Guangxi, Hainan).

Etymology. The specific name is a combination of Leuconola wilsonae and Meganola tarkabarka .
