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 (C3H8O3). Adults images were taken by a NIKON D90 digital camera, and genitalia were photographed by a Carl Zeiss Discovery V12 system. Plates were compiled by Adobe Photoshop software version 6.0. The type material of all new species was deposited in the Department of Entomology, College of Natural Resources and Environment, South China Agricultural University, Guangzhou, China.

Meganola paramediana Hu, Han, László, Ronkay & Wang sp. nov.
(Figs. 1 and 2)

  • HOLOTYPE: Male, CHINA, Mt. Daming, Guangxi, 11.VIII.2011, Min Wang, Yan-Qing Hu, Wen-Tang Wang & Hou-Shuai Wang; Slide No. hyq 251 (SCAU). Paratypes: 2 males, with the same data as the holotype; Slide Nos. hyq 252, hyq 253.

  • Diagnosis

    Meganola paramediana is externally similar to M. mediana László, Ronkay & Witt, 2010, but easily distinguishable by the following characters: thorax and collar of M. paramediana are white, while those of M. mediana are brown; crosslines of forewing are more obsolescent and median area of forewing is paler than in M. mediana. In male genitalia, M. paramediana has a slender and sharper uncus, a considerably shorter and more rounded proximal lobe of valva, a slightly broader, less rounded cucullus, a more slender tegumen, a significantly longer and more curved ampulla and a shorter, somewhat thicker aedeagus compared with those of M. mediana.

  • Description

    Adult (Fig. 1). Wingspan 18–19 mm. Male. Head, thorax and collar white; antenna brown, bipectinate; 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.

    Male genitalia (Fig. 2). Uncus relatively long, slender, apically pointed; tegumen short and narrow; valva medium-long, proximal lobe short, broadly rounded; cucullus broadened, apical margin more or less straight, covered with long and fine hairs; costal margin sclerotized, concave, basally humped; sacculus short; ampulla rather long extending over ventral margin of valva, reaping-hook-shaped, strongly sclerotized, apically rounded; vinculum relatively broad, medium long, V-shaped. Aedeagus short, relatively thick; vesica without cornuti.

    Female: Unknown.

  • Meganola nankunensis Hu, Han, László, Ronkay & Wang sp. nov.
    (Figs. 3 and 4)

  • HOLOTYPE: Male, CHINA, Mt. Nankun, 8.VI.2005, Min Wang; Slide No. hyq 728 (SCAU). Paratype: 1 male, with the same data as the holotype; Slide No. hyq 727.

  • Diagnosis

    Meganola nankunensis is very similar to M. Paramediana, but distinguishable by following characters: M. nankunensis is smaller in size (wingspan of M. nankunensis 15–16 mm versus 18–19 mm in M. paramediana); dark brown area of forewing in M. nankunensis is conspicuously larger than in M. paramediana, and not restricted to median area as in M. paramediana but also includes basal area; postmedial line is strongly arcuate while that of M. paramediana is wavy. In male genitalia, M. nankunensis has a conspicuously broader and shorter uncus; a more robust, considerably shorter and less arcuate ampulla, and a somewhat longer aedeagus compared with those of M. paramediana.

  • Description

    Adult (Fig. 3). Wingspan 15–16 mm. Male. Head, thorax and collar white; antenna light brown, white at base, bipectinate; labial palpus white. Abdomen medially brownish, anterior and posterior thirds covered by whitish scales. Forewing ground color grayish white, median area and distal half of basal area dark brown.

    Meganola wangi
    Hu, Han, László, Ronkay & Wang sp. nov.
    (Figs. 5 and 6)

  • HOLOTYPE: Male, CHINA, Jianfengling, Hainan, 12.IV.2009, Min Wang; Slide No. hyq 291 (SCAU).

  • Diagnosis

    Meganola wangi is similar to M. postmediana László, Ronkay & Witt, 2010, but easily distinguishable by the following characters: M. wangi is larger in size (wingspan of M. wangi 23 mm versus 17 mm in M. postmediana), and postmedial line is more or less straight in M. wangi while it is arcuate in M. postmediana. Differences between M. wangi and M. postmediana are well-expressed in the configuration of male genitalia. M. wangi has a somewhat longer, apically pointed uncus (shorter, apically rounded uncus in M. postmediana); 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.

    Male genitalia (Fig. 6). Uncus medium-long, broad at base, tapering, apically pointed; tegumen medium-long and broad; valva elongate, rather narrow, slightly shrunk at middle; cucullus less dilated, apically rounded quadrangular; costal margin humped at base, slightly concave medially; sacculus simple, short; ampulla relatively short and robust, very slightly curved medially and rounded apically; vinculum relatively short and broad, V-shaped. Aedeagus simple, tubular, relatively short and thick; coecum short and narrow; vesica without cornuti.

    Female: Unknown.

  • Distribution

    China: Hainan Province.

  • Etymology

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

  • Meganola donglashanensis
    Hu, Han, László, Ronkay & Wang sp. nov.
    (Figs. 7 and 8)

  • HOLOTYPE: Male, CHINA, Donglashan, Sichuan, 23.VII.2009, Min Wang; Slide No. hyq 685 (SCAU).

  • 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 László, Ronkay & Witt, 2010. 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.

    Male genitalia (Fig. 8). Uncus very short, apex pen-point-like; tegumen relatively short and narrow; valva medium-long; cucullus broadly rounded; costal margin concave, slightly sclerotized; a proximal lobe of valva rather large, rounded; ampulla well sclerotized, tapering, slightly arcuate, more or less horn-shaped, apically rounded; sacculus simple, short; vinculum very short, Vshaped. Aedeagus medium-long, slightly curved; vesica without cornuti.

    Female: Unknown.

  • Distribution

    China: Sichuan Province.

  • Etymology

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

  • Diagnosis

    Meganola longshengensis is closely related to M. wilbarka Hu, Han & Wang, 2013, but is smaller in size (wingspan of M. longshengensis 11 mm versus 15–18 mm in M. wilbarka), forewing ground color graphite-gray (grayish white in M. wilbarka). In M. longshengensis, a quadrangular costal patch of forewing is much paler than in M. wilbarka. Differences in male genitalia are as follows: a proximal lobe of valva in M. longshengensis is much shorter and narrower, cucullus is considerably broader and ampulla is somewhat shorter and thinner than in M. wilbarka, and aedeagus of M. longshengensis is characteristically S-shaped, while aedeagus in M. wilbarka is straight.

  • Description
