Note. The specimens labelled as BC ZSM Lep 48885, BC ZSM Lep 48674 and BC ZSM Lep 48673 have been used for barcoding. Intraspecific variation (n=3) is high, maximum pairwise distance 1,55%. Molecular distance based on the Kimura two-parameter model for COI DNA barcodes between T. glauca and the nearest species T. annamica is 4,77%. Barcode difference between T. glauca and T. indeterminata is 5,28%. T. glauca is not placed on the ID-tree on the same branch as T. annamica and T. indeterminata .

Diagnosis. Adult ( Figs 51–56 , 69–73 ). Wingspan 33–36 mm. This and subsequent two species represent a group of closely related species, hardly separable externally as well as by genitalia. Among them T. glauca can be recognized by yellowish-brown with metallic shining ground colour of forewing, greyish dusting in subbasal, medial and subterminal fields, strongly dentate crosslines, contrast border of subterminal line and yellow with brown-grey terminal band hindwing. Head, tegulae and patagia yellowish-white, patagia bordered with black, thorax pale yellowish-white with brown crest; ground colour of forewing yellowish-brown with metallic shining; basal field filled with yellowish-white, basal line marked as black streak; antemedial line black, waved, with thin whitish inner border; medial field yellowish-brown with diffused medial shadow divided for two parts; orbicular as small white dot encircled by black; reniform small, whitish, brown inside, outlined inwardly with black; whitish dash and suffusion lies outside reniform toward to postmedial line and costal margin; postmedial line dentate, bordered outwardly with thin white line; subterminal field rather wide, yellowish-brown, with metallic shining; subterminal line dentate, blackish-brown, diffused inwardly, outlined with white outwardly; subterminal line with prominent whitish spot between two extensions of subterminal line; terminal line as row of black streaks; cilia yellowish-brown, whitish opposite veins. Hindwing with yellow basal part and broad, brownish-grey terminal band; cilia pale grey-brown.

Male genitalia ( Figs 110, 111 ). Uncus relatively short, thin, curved; tegumen broad, shorter than vinculum, with prominent penicular extensions; vinculum broadly V-shaped; transtilla with broad leave-like lobes; juxta shield-like, broad and high, more or less rounded; valva relatively short, with almost parallel margins, tegumen narrow, elongate, in apical third ventral margin of valva gradually constricted distally, apex rounded; harpe lies in distal third of valva, almost straight, relatively short. Aedeagus relatively short, extended distally, thick; carina sclerotised; vesica broadly-tubular, rather short, bearing large basal diverticulum covered with field of small spines and large apical diverticulum with two patches of small dense cornuti.

Female genitalia ( Figs 129, 130 ). Ovipositor quadrangular, papillae anales rather broad; anterior and posterior apophyses short, broad, equal in length; antrum broadly-triangular, weakly sclerotised, ductus bursae long, very short, membranous; corpus bursae rounded, sclerotised and ribbed in caudal part in joining with ductus bursae.

Distribution and bionomy. North India (Meghalaya); * China (South Yunnan); North Vietnam (Lao Cai, Tonkin), North Myanmar (Putao); North Thailand (Chiang Mai). The species occurs in secondary and primary forest at elevation 800–1500 m. Moth flies in January, March, April, May, June and October.
