Five New Species and Five New Records of the Genus Meganola (Lepidoptera: Nolidae: Nolinae) from China

Abstract The paper describes 5 new species of Meganola Dyar, 1898 (M. paramediana, M. nankunensis, M. wangi, M. donglashanensis and M. longshengensis spp. nov.) from China. Five described species, M. latiscripta László, Ronkay & Witt, 2005, M. tarkabarka László, Ronkay & Witt, 2010, M. semirufa (Hampson, 1894), M. galsworthyi László, Ronkay & Witt, 2010 and M. indistincta (Hampson, 1894) are reported from China for the first time. Adults and genitalia are illustrated.

The genus Meganola Dyar, 1898 was first described from North America and type species, Meganola conspicua Dyar, 1898, was designated by monotype. Meganola is a large and morphologically rather diverse genus, which is widely distributed on all continents, although it proved to be the most species rich in the mountains of Southeast Asia. The overwhelming majority of Meganola species known to occur in China are represented in historical collections preserved mostly in the Natural History Museum, London, United Kingdom. The Nolinae material of the famous German entomologist Hermann Höne is still largely unidentified, although it was collected in the 1930s and is easily accessible in the Zoologische Forschungs Institute and Museum Alexander Koenig, Bonn, Germany.
Fortunately, the increasing number of Chinese entomologists have assembled a considerable collection of interesting Nolinae taxa of China. Detailed study is now under way by the authors of this paper. Last year, we described 5 new species from China and adjacent regions and summarized the status of research on the genus Meganola (Hu et al. 2013). Recently collected materials from China have resulted in the discovery of 5 new species and 5 new records of previously described species. In addition, the female genitalia of M. tarkabarka and M. galsworthyi are described here for the first time.

Materials and MetHods
All of the material studied was collected by light traps. Abdomens were macerated in 10% sodium hydroxide (NaOH) and mounted in glycerin (C 3 H 8 O 3 (Fig. 1). Wingspan 18-19 mm. Male. Head, thorax and collar white; antenna brown, bi-pectinate; labial palpus white with light brown at base. Abdomen grayish brown. Forewing ground color grayish white; median area brown, significantly darker in costal third. Basal line poorly visible, only represented by pale brown scales; antemedial line inconspicuous, arcuate; medial line pale and closer to postmedial line than to antemedial line; postmedial line wavy; subterminal line pale brown, diffuse, rather broad and slightly wavy. Hind wing pale grayish brown; discal spot blurred.

Distribution
China: Guangdong Province.

Etymology
The specific name is derived from the type locality of the new species: Nankun. ; a considerably narrower valva with a more or less rounded quadrangular cucullus (a welldeveloped, broadly rounded cucullus in M. postmediana); a shorter, slightly thicker, less arcuate ampulla and a much shorter and broader vinculum. The main difference between the 2 species is found in the configuration of aedeagus and vesica, i.e., M. wangi has a rather short, simple aedeagus with vesica lacking cornuti while aedeagus of M. postmediana is rather long, narrow, and vesica is armed by a long, robust cornutus. Description Adult (Fig. 5). Wingspan 23 mm. Male. Head dark gray; antenna brown, bipectinate; labial palpus short, blackish brown. Thorax brown; collar blackish, tegulae pale brownish white; abdomen dark brown. Forewing ground color brownish gray, median area blackish brown. Basal line absent; antemedial line dark brown, smoothly curved; medial line blackish, running closer to postmedial line than to antemedial line; postmedial line blackish, ventral two-third straight, curved at costal third; subterminal line pale brown, wavy; terminal area suffused with pale brown scales; cilia pale brownish white. Hind wing grayish brown, discal spots faint.

Etymology
The specific name is dedicated to Wen-Tang Wang for his kind help in collecting the Nolinae materials.

Diagnosis
The external appearance of M. donglashanensis is reminiscent of certain species of Nola rather than Meganola, but male genitalia clearly indicate that this species belongs to the Meganola indistincta (Hampson, 1894) species-group, and that it is closely related to M. geoffmartini . Differences compared with M. geoffmartini are as follows: forewing ground color of M. donglashanensis is white (gray in M. geoffmartini), a proximal lobe of valva is without dentation (conspicuously dentate on outer margin in M. geoffmartini), and ampulla of M. donglashanensis is more or less straight while ampulla in M. geoffmartini is strongly arched. Description Adult (Fig. 7). Wingspan 15 mm. Male. Head clear white; antenna pale brownish white, bipectinate; labial palpus white with pale brown scales. Prothoracic collar and tegulae yellowish white; thorax and abdomen brownish yellow. Forewing ground color bright white with fine brownish suffusion in median area and yellowish brown patches at costal margin. Basal line faint, represented by only a brown spot at costal margin; antemedial line shadow-like; medial line arcuate, dark brown; postmedial line pale brown, shadow-like; subterminal line rather wavy, faint, diffuse, consisting of groups of pale brown scales; terminal line diffuse, consisting of pale brown scales. Hind wing bright white, discal spot faint.

Distribution
China: Sichuan Province.

Etymology
The specific name is derived from the type locality of the new species: Longsheng.
