Redescription.

Measurements (10 males, 9 females). Body length (from apex of head to tip of forewings): male 11.7-13.4 mm, female 13.0-14.9 mm; head length (from apex of cephalic process to base of eyes): male 1.33-1.50 mm, female 1.50-1.65 mm; head width (including eyes): male 1.30-1.60 mm, female 1.48-1.75 mm; forewing length: male 9.4-10.8 mm, female 10.2-11.9 mm.

Coloration. General coloration as in generic description (Figs 1A View Figure 1 , 2G-H View Figure 2 ). Vertex dark brown with five light ochraceous streaks: along median carina in anterior third (in some specimens, the whole median carina is light), along each lateral carina subapically and along each lateral carina basally, the latter streaks being sickle-shaped and curved to median carina at the base (Fig. 8A View Figure 8 ). Frons light ochraceous with small dark brown spots along intermediate and lateral carinae, frons base slightly infuscated (Fig. 8C View Figure 8 ). Forewing membrane pattern as in Fig. 3D View Figure 3 . Hind wing membrane with a dark brown streak along the apical portion of CuA1 vein, extending along hind wing apical margin.

Structure. Head with cephalic process moderately long, not inflated (Figs 8A-C View Figure 8 ). Vertex (Fig. 8A View Figure 8 ) with ratio of length at midline to width between eyes 1.6-2.0. Transition of vertex to frons relatively sharp, almost angular in lateral view (Fig. 8B View Figure 8 ). Frons relatively narrow, with ratio of length at midline to maximum width 2.6-3.0.

Male genitalia. Pygofer, in lateral view (Fig. 8E View Figure 8 ), with dorso-posterior margin produced into a short and broad lobe; in ventral view (Fig. 8F View Figure 8 ) much longer than in dorsal view (Fig. 8D View Figure 8 ) with ratio of ventral to dorsal length about 4.0. Gonostyles (Fig. 8E-F View Figure 8 ) large, broad medially, with dorsal margin weakly sinuate. Aedeagus (Fig. 8G-I View Figure 8 ) with endosomal processes extended posteriad and strongly curved dorso-anteriad, relatively short, their apices not reaching the base of phallobase; phallobase with one pair of large, strongly inflated dorsolateral lobes (Fig. 8H View Figure 8 ), their apices blunt, and one pair of small, thumb-like ventral lobes, directed posteriad (Fig. 8I View Figure 8 ). Segment X, in lateral view, narrow basally, widening to apex beyond middle, apex subacute (Fig. 8E View Figure 8 ); in dorsal view, relatively short and broad in dorsal view, widest medially, with ratio of length to maximum width 1.2-1.3 (Fig. 8D View Figure 8 ).

Female genitalia as in generic description.

Distribution.

Widely distributed in tropical, subtropical and temperate eastern Asia (Japan, China, Korea, Vietnam, Laos, northeastern India and Nepal).

Ecology and economic importance.

Adult O. lunulifer was reported as a minor pest of leaves of Morus alba L. ( Pu and Mao 2012) and Camellia oleifera Abel in southeastern China ( Zhao et al. 2013). Matsumura (1910) listed " Anagnia splendens " among pests of sugarcane in Taiwan; this record perhaps also refers to O. lunulifer .

Remarks.

Erroneously according to Metcalf (1946), Matsumura (1905a, b) considered O. lunulifer to be a junior synonym of Anagnia splendens (Germar). As he probably studied material from Japan, the description and illustration of " Anagnia splendens " in Matsumura (1905a) probably refer to O. lunulifer (i.e., the only Orthopagus species currently confirmed from Japan). The same is probable for the records and a figure of " Anagnia splendens " from Okinawa and Taiwan published in Matsumura (1905b and 1910, respectively).

Melichar (1912) differentiated O. elegans , O. helios and O. lunulifer based on slight differences in the transparency of the forewing membrane, extent of the dark brown apical band on the forewing and the shape of frons. Based on a study of material from Taiwan, Schumacher (1915) suggested that Orthopagus helios and O. elegans described by Melichar (1912) belong to the same species. However, his synonymisation of O. helios var. diffusus Melichar and O. elegans Melichar under O. helios Melichar was not widely accepted ( Metcalf 1946). We have examined the corresponding type specimens and additional specimens from the same series collected by H. Sauter in Taiwan and currently deposited in HNHM, MFNB, MMBC, SDEI, and SNSD, and confirm here Schumacher’s conclusion. Simultaneously, we suggest that O. helios should be treated as a junior synonym of O. lunulifer because we consider the differences among these taxa listed by Melichar (1912) to represent intraspecific variation. We designate here the lectotypes for O. elegans , O. helios and O. helios var. diffusus to stabilize the nomenclature according to Article 74 of ICZN (1999).

Liang (1996) designated the lectotype for O. lunulifer , and provided a left lateral view of male genitalia for this species. Detailed illustrations of the male and female genitalia (but no detailed description) were also provided for O. lunulifer by Song et al. (2016d, 2018).

The single male specimen examined from Nepal (Chitwan National Park) is identical in external characters to specimens of O. lunulifer from Japan, China, Taiwan and Vietnam. However, it differs in the shape of the lobe on the dorso-posterior margin of the pygofer which is smaller (shorter and simply angular) than in the rest of O. lunulifer males studied. The phallobase of this specimen could not be sufficiently compared as its membranous lobes failed to inflate during the preparation. More specimens and data are needed to confirm the identification.
