Note. The specimens labelled as BC ZSM Lep 58663, and BC ZSM Lep 58664 have been used for barcoding. Molecular distance based on the Kimura two-parameter model for COI DNA barcodes between T. subflava (based on short sequences only of 307bp) and T. helmuti is 4,91%.

Diagnosis. Adult ( Figs 17–21 ). Wingspan 50–56 mm. This species and T. succincta are very similar by externally, but differ well By structure of the male genitalia. Antennae of male simple. Head, patagia and tegulae whitish, thorax bronze-brown. Forewing somewhat narrower compared with allies, having oblique outer margin. The ground colour of forewing is bronze-brown with intensive greyish and whitish dusting in medial and subterminal fields; crosslines dark brown, dentate and waved; orbicular small, white; reniform prominent, bronzebrown inside, with two white spots in basal and apical parts, encircled inwardly by brown; two well defined white spots lie outside of reniform toward postmedial line; subterminal line broad, dentate, subterminal field bronzebrown, with 3–4 pale greyish spots. Hindwing yellow or orange-yellow, with narrow diffused terminal band (in some specimens terminal band is not expressed).

Male genitalia ( Fig. 95 ). Male genitalia of T. subflava differ from related T. succinta and T. tibetica by beaklike shape of uncus, rather broad shape of valva, large, massive harpe positioned on apical half of ventral margin of valva and by structure of aedeagus, which is rather long and thinner compared with related species, with broad sclerotised carina and broad unarmed vesica. Uncus rather short, massive, beak-like; tegumen broad, somewhat shorter than vinculum, with prominent penicular extensions; vinculum V-shaped, with saccus; transtilla with moderate lobes; juxta shield-like; valva large, moderate long, curved basally, with parallel margins, constricted distally, having oblique distal margin; harpe lies in distal third of valva, very large, massive, slightly curved apically and; slightly extends distal margin of valva. Aedeagus large, straight, extended apically; carina broad, sclerotised, with scobinate patch; vesica bulbous-tubular, bearing sclerotised ribbed patches in subapical area.

Female genitalia ( Fig. 125 ). The female genitalia of T. subflava are similar to those of T. naumanni having short triangular antrum, short membranous ductus bursae and ribbed sclerotised patch in the caudal part of corpus bursae. Ovipositor quadrangular, papillae anales moderate broad; anterior and posterior apophyses moderate long, equal in length; antrum triangular, weakly sclerotised; ductus bursae short, membranous, in joining with corpus bursae sclerotised; corpus bursae elongated sack-like, with sclerotised ribbed patch in joining with ductus bursae and small extension in caudal part.

Distribution and bionomy. Northwest, Central, Southeast and Southwest China (Prov. Shaanxi, Jiangxi, Taiwan Isl. Guangdong, Sichuan, Yunnan), North India ( Hindustan, Assam, West- and East Ghats, Meghalaya), Nepal, Thailand, Vietnam. The species occurs in montane forest at elevation 900–2000 m. Moths fly in April, May, June, July, August.
