Diagnosis. The separation of this species and C. gladiata has been given in the diagnosis of the previous species. Cidariplura nanling can be distinguished from the allopatric C. luding sp. nov. by the nearly rounded forewing discocellular spot, rather than the narrowed spot observed in C. luding ; the subcostal region of the forewing postmedial line is incurved rather than slightly excurved; the subtornal region of the hindwing postmedial line is incurved rather than straight; the distal portion of the valva is more rounded rather than tapering; the costal process of the valva is less curved towards ventral part; the scale tufts on the dorsal surface of the saccular process are less developed. The female genitalia have no remarkable difference between these two species.

Description. Measurements. Forewing length 17–20 mm in males (n= 14); 16–17 mm in females (n= 2). Eye round; antenna ciliate, male with a pair of long bristles on each segment, length of bristle 2 X diameter of medial region of shaft. Head, all segments of thorax, as well as femur, tibia and 1 st tarsal segment chocolate brown. Male labial palpus ( Fig. 31 ) modified as follows: 1st segment very long, upcurved along frons, surpassing vertex, smoothly covered with scales; 2 nd segment bent at right angle to 1 st, slender, slightly curved, nearly as long as 1st, reaching the anterior part of thorax, internally with ochreous scales which are elongated and enlarged at their apices; 3 rd segment long and stout, nearly 1. 4 X longer than 2 nd, basal part of labial palpus wider than medial part, internally with long ochreous scales which are slender and almost twice as long as those on 2 nd. Labial palpus in female: 3 rd shorter than 2 nd, slender, tapering towards apex. Legs normal, male foretibia with apical spine. Forewing broad, slightly excurved, apex slightly protruded; ground coloration chocolate brown; white antemedial and postmedial lines slender, the former oblique, wave-like, the latter excurved outward at discal cell part; discocellular spot white, nearly rounded; outer margin white; marginal scales chocolate brown. Hindwing chocolate brown; postmedial line white; outer margin white; marginal scales chocolate brown. Abdomen brown, 8th segment unmodified. Male genitalia ( Fig. 40 )—Uncus broad, stout, apex hook-like. Tegumen and vinculum long, equal in length; saccus Vshaped. Valva trifurcate, costal process heavily sclerotized, curved ventrally at halfway point, distal portion of valva tongue-like, saccular process narrow, stout, nearly 0. 5 X shorter than distal portion of valva, covered with sparse hair tufts. Juxta plate-like, transtilla indistinct. Aedeagus stout, straight, nearly as long as valva; vesica densely scobinate, without cornutus. Female genitalia ( Fig. 50 )—Papillae anales membranous with short hair-like setae; both pairs of apophyses slender; ductus bursae with a pair of broad lateral sclerites. Corpus bursae elliptical, ca. 1. 33 X longer than ductus bursae, basal half surrounded by dense internal spinose patch; ductus seminalis arising from lateral base of corpus bursae, broadened and coiled at basal portion.

Distribution and phenology. China (Guangdong, Yunnan). The species is presumably univoltine and adults occur from June to July.

Etymology. Named after the type locality, noun in apposition.
