Diagnosis. This species is very similar to C. brevivittalis ( Figs 17–20, 23, 24 View FIGURE 17 – 26 , 47, 48 View FIGURE 47 – 56 , 58 View FIGURE 57 – 67 , 71 View FIGURE 68 – 78 , 83 View FIGURE 79 – 89 ) inn external appearance, but differs from the latter in having the more distinct white hindwing medial line. In the male genitalia, C. bilineata can easily be distinguished from C. brevivittalis by the valval trifurcate structures being strongly prominent, the distal portion of valva rectangular with a saccular process being elongate; and the broader corpus bursae. Owada (1994) erroneously stated that the male antennal structures differ in both species, i.e.
bipectinate in bilineata and ciliate in brevivittalis . This distinction is inappropriate since the antennae of both species are ciliate with a pair of long bristles (length 3 X diameter of shaft in the median region) in each segment.
Description. Owada (1987: 43–44) gave a detailed description of this species under a misidentified name C. brevivittalis based on Japanese specimen.
Distribution and bionomics. This species was mentioned to occur in Taiwan, Japan, Korea and China (Owada, 2011). The distribution of this species in China need to be revised due to the possible confusions with C. ochreistigma (Leech, 1900) , S. China; 67. C. ilana Wu & Owada sp. nov., Taiwan. Bar scale= 1 mm.

C. brevivittalis . The Taiwanese populations of C. bilineata lives in low to mid-elevations of primary broadleaved forests. The adults occur from June to August, then October and December, possibly bivoltine. It is known that the larvae feed on mosses in Japan (Yamamoto 1965; misidentified as C. brevivittalis ).
Taxonomic notes. The known distribution of C. bilineata (TL: Alishan, Taiwan) and C. brevivittalis (TL: Darjiling, N. E. India) needs to be revised due to possible misidentifications. From our examination of the specimens available, we found that C. bilineata occurs in Taiwan, Japan and Korea, whereas C. brevivittalis occurs in N. India and Nepal (first recorded in the present study: 1 male and 1 female, E. Nepal, Kosi, Pheksinda, 780 m, 6-13-V-1994, leg. M. S. Limbu, ex. H. Yoshimoto coll., coll. NSMT, Figs 23,24 View FIGURE 17 – 26 , respectively). Although the taxon Elyra albifascia (TL: Khasis, N. E. India, female) was regarded as the junior synonym of bilineata by Owada (1994), it should be treated as the junior synonym of C. brevivittalis (syn. nov.) considering the type localities. Chen (1999) included Guangxi (S. China) and Tibet (S. W. China) in the distribution of his “ C. brevivittalis ”; however, the illustrated male genitalia (p. 1298, fig. 685) turned out to be those of C. bilineata .

Diagnosis. This new species can be distinguished from C. ochreistigma by the orbicular and reniform stigmata being dark brown rather than ochreous; by the saccular process being stouter, shorter rather than elongated and slender; and by the aedeagus being shorter rather than slender and longer.
Description. Measures. Wingspan 36–37 mm in males (n= 3); 35–36 mm in females (n= 3). Eye large; antenna ciliate, male with a pair of long bristles on each segment, length of bristle 4 X diameter of shaft in median region. Head, all segments of thorax as well as femur, tibia and 1st tarsal segment chocolate brown. Male labial palpus ( Fig. 76 View FIGURE 68 – 78 ) specialized as follows: 1st segment very long, upcurved along frons, surpassing vertex, smoothly covered with ordinarary scales; 2nd segment bent at a right angle from the 1st, slender, slightly curved, as long as 1st, reaching the medial part of thorax, internally with specialized ochreous scales which are elongated and enlarged at their apices; 3rd long and stout, nearly 0.75 X shorter than 2nd, internally with long ochreous scales which are slender and almost twice as long as those in the 2nd. Labial palpus in female normal, sickle-shaped. Legs normal, male foretibial with presence of a spine at the apex ( Fig. 87 View FIGURE 79 – 89 ). Forewing broad, slightly excurved, apex near right-angled; ground coloration brown; antemedial and postmedial line ochreous, excurved at nearly vein Cu 1+2A and M1, respectively; orbicular and reniform stigmas black the former round, small, the latter moderate size, lunate- shaped; marginal part dark brown; marginal scales brown. Hindwing brown; discal spot short, transverse, dark brown; medial line straight, ochreous; marginal part covered with small black stigma in each cell; marginal scales brown. Abdomen brown, 8th segment unmodified. Male genitalia ( Figs 55, 56 View FIGURE 47 – 56 )- Uncus broad, stout. Tegumen and vinculum long, same in length; saccus V-shaped. Valva trifurcate, costal process stout with lateral semi-circular expansion, distal portion of valva broad, membranous, saccular process small, short, digit-like without hair tufts on apex. Juxta long plate-like, transtilla indistinct. Aedeagus stout, straight, 0.67 X shorter than valva; vesica well scobinated, without cornutus. Female genitalia ( Fig. 67 View FIGURE 57 – 67 )- Ovipositor lobe membranous with short hair-like setae; both pairs of apophyses slender, moderate length; ductus bursae long, with a pair of broad lateral sclerites fused at basal portion. Corpus bursae elliptic, as long as ductus bursae, basal half part wrinkled; ductus seminalis arising from lateral side of corpus bursae, slightly broadened and coiled at basal portion.
Etymology. The species is named after the collecting locality of type series, Ilan County, northern eastern Taiwan.
Distribution and bionomics. This new species, endemic in Taiwan, occurs in low to mid- elevations of northern Taiwan. The adults occur only in May based on collecting records, possibly univoltine.
Taxonomic notes. This new species is superficially similar to C. nigristigmata (Leech, 1900) ( Figs 32 View FIGURE 27 – 34 , 51, 52 View FIGURE 47 – 56 , 65 View FIGURE 57 – 67 , 74 View FIGURE 68 – 78 , 89 View FIGURE 79 – 89 ) in S. China in having the forewing reniform stigma dark brown and V-shaped. The genital structures of this new species actually shows its closest relationship with C. ochreistigma (Leech, 1900) ( Figs 31 View FIGURE 27 – 34 , 53, 54 View FIGURE 47 – 56 , 66 View FIGURE 57 – 67 , 75 View FIGURE 68 – 78 , 88 View FIGURE 79 – 89 ) in S. China rather than C. nigristigmata , which is close to C. hani Chen, 1992 and C. subhani Zhang & Han, 2009 in Xizhang (= Tibet), W. China, in the genital structures. C. ilana and C. ochreistigma form a separate lineage in Cidariplura based on three particular character states of the male genitalia: the costal process heavily sclerotized and broader with a ventral semi-circular expansion; the saccular process digit-like without hair tufts; and a pair of broad lateral sclerites of ductus bursae fused at the basal portion.
