Diagnosis. The presence of a ochreous spot at the tornal area of the hindwing can be regarded as the most distinct character for this species. This species is superficially similar to C. gladiata but differs from the latter in having the smaller body size (wingspan 30–35 mm in C. gladiata ) and the darker coloration. The second segment of male labial palpus of C. shanmeii is very short, ca. 1/3 of the third segment, while it is as long as the third segment in C. gladiata . C. shanmeii can also be distinguished from C. gladiata by the male antenna with the ciliae 2X as long as the diameter of shaft in median region (3X in C. gladiata ); by the three apical parts of the trifurcate valva being prominent and sclerotized; by the narrower aedeagus and the shorter ductus bursae.

Description. Measures. Wingspan 26–28 mm in males (n= 51); 27–28 mm in females (n= 9). Eye large; 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. 69 ) specialized 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, 0.67 X shorter than 1st, reaching the anterior part of thorax, internally with specialized ochreous scales which are elongated and enlarged at their apices; 3rd long and stout, 3 X longer 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, sickleshaped. Legs normal, male foretibial with presence of a spine at the apex ( Fig. 80 ). Forewing broad, slightly excurved, apex near right-angled; ground coloration chocolate brown; antemedial and postmedial line slender, light ochreous, the former obliqua, wave-like, the latter smoothly excurved outward at discal cell part; orbicular and reniform stigmas white, the former small, the latter moderate size, 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 the outerside of tornus area; outer margin ochreous; marginal scales chocolate brown. Abdomen brown, 8th segment unmodified. Male genitalia ( Figs 37, 38 ) – Uncus broad, stout, apex hook-like. Tegumen and vinculum long, same in length; saccus V-shaped, madial part elongated anteriorly. Valva trifurcate, costal process long, heavily sclerotized, apex curved ventrally, distal portion of valva broad, sclerotized, saccular process narrow, elongated, covered with short hair tufts. Juxta plate-like, transtilla indistinct. Aedeagus stout, straight, 1.25 X longer than valva; vesica well scobinated, without cornutus. Female genitalia ( Fig. 64 ) – 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 flatterned at basal portion. Corpus bursae elliptic, 1.33 X longer than ductus bursae, basal half part wrinkled; ductus seminalis arising from lateral base of corpus bursae, broadened and coiled at basal portion.

Etymology. The new species is named after its holotype locality, Shanmei, Chiayi County, Taiwan.

Distribution and bionomics. This is a rather common species endemic in Taiwan. It occurs in lowelevations open canopy forests across the whole island. According to the collecting records, the adults occur in March, May, then reappear from July to November, being possibly bivoltine or multivoltine.

Taxonomic notes. The name ochreimacula was first proposed as an aberration of gladiata by Strand (1919). Based on the comparison under the diagnosis part, this taxon is remarkably different with C. gladiata . Since this name is unavailable (ICZN code 45.6.2.), we describe this distinct species as C. shanmeii Wu & Owada sp. nov.
