Notes. Wu et al. (2013) described C. shanmeii with the illustration of the holotype of C. shanmeii , however the illustrated structures in Wu et al. (2013: figs 37, 38, male; 64, female; 69, labial palpus; 80, male foreleg), actually belong to the new species, C. hbun sp. nov., described below.

Diagnosis. Externally C. shanmeii and C. hbun are difficult to be separated, but the former species can be distinguished from the latter by the narrowed white forewing discocellular spot, rather than a wider and more yellowish-white spot; the costal process of the valva is digitiform rather than stouter and curved downwards; the distinctively shorter distal portion of valva rather than nearly equal in length as costal process; the digitiform, straight costal process rather than curved ventrally and tapering; the saccular process is extremely small and curved rather than robust and rod-like pointing parallelly with distal portion of valva; the ductus bursae is extremely narrowed compared to the moderate width of other species in the complex.

Re-description. Due to the existence of specimens belonging to both C. shanmeii and C. hbun sp. nov. in the paratype series of C. shanmeii (sensu Wu & Owada, in Wu et al., 2013), we re-describe C. shanmeii herein to clarify the identity of that species. Measurements. Forewing length 12–14 mm in males (n= 17); 12–14 mm in females (n= 5). Eye round; antenna ciliate, male with a pair of long bristles on each segment, length of bristle 2 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. 28 ) modified as follows: 1st segment very long, upcurved along frons, surpassing vertex, smoothly covered with ordinary scales; 2nd segment bent at a right angle from the 1st, slender, slightly curved, 0. 5 X shorter than 1st, reaching the anterior part of thorax, internally with specialized ochreous scales which are elongated and enlarged at their apices; 3rd segment long, 3 X longer than 2nd, basal part of labial palpus as wide as medial part, internally with long ochreous scales slender and almost twice as long as those in the 2 nd segment. Labial palpus in female: 3 rd shorter than 2 nd, slender, tapering towards apex. Legs: male foretibia with apical spine. Forewing broad, slightly excurved, apex nearly forming right angle; ground coloration chocolate brown; antemedial and postmedial line slender, light ochreous, the former oblique, wave-like, the latter smoothly excurved outward at discal cell part; discocellular spot white, slender and lunate-shaped; submarginal line slender, ochreous, wave-like; outer margin ochreous; marginal scales chocolate brown. Hindwing chocolate brown; medial line ochreous with one ochreous spot situating at outside of tornal area; outer margin ochreous; marginal scales chocolate brown. Abdomen brown, 8th segment unmodified. Male genitalia ( Fig. 43 )—Uncus broad, stout, apex hook-like. Tegumen and vinculum long, equal in length; saccus V-shaped, medial part elongated anteriorly. Valva trifurcate, costal process, straight and digitiform, distal portion of valva broad, saccular process short, curved and digitiform. Juxta plate-like, transtilla indistinct. Aedeagus stout, straight, 1. 25 X longer than valva; vesica densly scobinate without cornutus. Female genitalia ( Fig. 53 )—Papillae anales membranous with short hair-like setae; both pairs of apophyses slender, moderate length; ductus bursae as long as corpus bursae, with a pair of slender lateral sclerites. Corpus bursae elliptical, basal half part surrounded by dense internal spinose patch; ductus seminalis arising from lateral base of corpus bursae, broadened and coiled basally.

Distribution and phenology. Endemic to Taiwan. The adults occasionally occur from March to November.
