Hu, Yan-Qing, Yu, Yong & Wang, Min, 2019, Taxonomic study of the genus Meganola (Lepidoptera, Nolidae, Nolinae), with three new species and a new record from China, Zootaxa 4586 (2), pp. 289-294 : 292-293

Meganola wulongensis sp. n.

(Figs 15–17)

Type material. Holotype: male, Wulong, Chongqing, 9–10.vii.2018, Leg. Yong Yu & Yanqing Hu. Two paratypes: 1 male, Fangjia, Nanbu county, Sichuan Prov., 7–8.vii.2018, Leg. Yong Yu & Yanqing Hu; 1 male, Rongjiang county , Guizhou Prov., 16–18.vii.2018, Leg. Yong Yu & Yanqing Hu.

Diagnosis. In the male genitalia, the new species resembles Meganola zegzugminta László, Ronkay & Ronkay, 2014 (Figs 19 & 20), but these two species of wing pattern are completely different (Figs 15 & 18). In the new species, the antemedial and medial lines are poorly visible and fused with medial fascia, the postmedial line is zigzag, the subterminal line is striped, while in M. zegzugminta the antemedial and medial lines are fine and distinct without medial fascia, the postmedial line is wavy, the subterminal is feeble and represented with a row of short lines. In the male genitalia, the new species has a broad uncus, a narrow tegumen, a curved harpe with dentations, a short saccus and aedeagus, while M. zegzugminta has a slender uncus, a relatively broad tegumen, a relatively straight harpe without the obvious dentation, a long saccus and aedeagus.

Description. Adult (Fig. 15). Wingspan 12–15 mm. Head greyish brown; antenna brown, bipectinate in male; labial palpus brown. Thorax darker brown. Collar greyish brown. Abdomen brown. Forewing ground color pale greyish brown, costal margin area darker brown from wing base to the subterminal line, the medial fascia blackish brown; basal line darker brown; antemedial and medial lines poorly discernible; postmedial line blackish brown, excurved to vein R 4, incurved and arched to vein M 3, then incurved to inner margin; subterminal line darker brown, arched. Hindwing more or less greyish brown.

Male genitalia. (Figs 16 & 17). Uncus broad, tapering, sharped apically; tegumen thin, broad basally, medium long; valva slender, narrow medially; costal margin sclerotized; sacculus small; harpe upcurved distally, pointed apically, with dentations at costal margin; saccus relatively shorter than uncus, V-shaped. Aedeagus cylindrical; vesica without cornuti.
