Asuridia rubripennis: Inoue, 1988, Tyo to Ga 39(2): 102, fig. 8.; Chang, 1989: 53, fig.; Inoue & Kishida, 1992: 167; Wang, 1994: 130; Fu et al., 1995: 58; Wang, 1996: 229, fig.
Asuridia carnipicta: sensu Matsumura, 1931: 969, fig.
Material examined. Type material. Holotype, male, TAIWAN, “ Taoyuan Hsien ” (correctly Ilan County, not Taoyuan County), Chihtuan (= Mingchih), 23-IV-1983, leg. B. S. Chang (coll. BMNH).
Additional material. TAIWAN. 1 female, with the same collecting data as the holotype, slide NMNS1282-1266; 1 male, [Ilan County], Chihtuan (= Mingchih), 14-V-1982, leg. B. S. Chang, slide NMNS1282-1067 (coll. NMNS); 1 male, Nantou County, Beidongyenshan, 2000 m, 22-VI-2009, leg. Y. M. Chen, slide TFRI117015 (coll. TFRI); 1 male, Kaohsiung County, Tengchih, 1600 m, 10-VIII-2004, leg. M. C. Lin (coll. ESRI).
Diagnosis. A. rubripennis can easily be separated from A. inouei sp. nov. and A. kishidai sp. nov. by the more strongly curved forewing postmedial line. In the genitalia: by the presence of a sclerotized costal process; the absence of a subapical costal extension (digitus); and the ventral opening of the ostium bursae being U-shaped, rather than V-shaped as in A. kishidai.
Description. Adult (Figs 1, 3, 4). Wingspan 23–25 mm in male (n= 4); 25 mm in female (n= 1).
Head: Antenna ciliate, male with a pair of long bristles on each segment, bristles as long as the diameter of antennal shaft in median region. Head, thorax and distal part of abdomen light rosy-red, remaining part of abdomen pinkishochreous. Forewing ground apex pointed; outer margin smoothly excurved; ground color light rosy-red; costal margin dark grey; transversal lines prominent, dark grey, antemedial line double-peaked; medial line nearly straight, postmedial line protruded outwards near discal cell then curved inwards mostly to CuA 1, finally curved outwards to tornus; submarginal striae short; marginal scales dark ochreous. Hindwing light pinkish-ochreous; medial line less prominent, wide, pale grey; marginal scales dark ochreous. Male genitalia (Figs 11, 12). Uncus strongly sclerotized, curved downward, apex tapering; tegumen long and narrow; vinculum short; saccus U-shaped with apex slightly protruded; juxta small and plate-like; valva sclerotized, apicalcostal process long, sclerotized, cuneate-digitiform; distal portion of valvae round, membranous; sacculus long, stout, apex of saccular process shortly conical. Aedeagus stout, spinose patches arising from ventral side of manica; vesica expanded basaly and gradually tapering distally, dorsal surfaces scobinate, two short spinose patches arising from dorsal part of vesica; medial section with small scletotized plate. Female genitalia (Fig. 15). Ovipositor lobe membranous with short hair-like setae; gonapophyses elongated, length of anterior and posterior ones equal; ostium bursae sclerotized, stout, ventral part strongly incised, rather U-shaped; ductus bursae very short, heavily sclerotized; corpus bursae sac-like, posterior half covered with dense spinose scobination; ductus seminalis arising from medial part of corpus bursae.
Notes. The examined material is all from Taiwan, and the species appears endemic there, its range encompassing low to mid-elevation primarily broad-leaved forests. The adults occur from April to June, and in August. The immature stages remain unknown. The female is described here for the first time. The holotype of rubripennis in the BMNH was re-examined in this study. In the original description of rubripennis, Inoue (1988) gave incorrect figure numbers that should be transposed (Figs 7, 8) for one male paratype and the holotype. The latter is illustrated herein (Figs 1, 2). We also dissected one male and one female specimen recently collected from the type locality of rubripennis (Chihtuan = Mingchih) that had similar wing pattern to the holotype. The newly dissected male genitalia are remarkably different from the male genitalia illustrated in Inoue’s (1988: 103, fig. 9) paper under the name “ A. rubripennis,” and in fact his illustrated paratype belongs to a new species, described next.
