Note. The specimen labelled as BC ZSM Lep 48884 have been used for barcoding. Molecular distance based on the Kimura two-parameter model for COI DNA barcodes between T. indeterminata and the nearest species T. annamica is 4,44%. Barcode difference between T. indeterminata and T. glauca is 5,28%.
Diagnosis. Externally T. indeterminata is very similar to T. glauca, but differs by somewhat bigger size, darker and duller yellowish-brown with metallic shining ground colour of forewing, less developed greyish dusting, less dentate and more contrast whitish transversal lines and by deep yellow with dark black-brownish terminal band hindwing. The new species well separated from T. glauca by the differences in their DNA barcodes.
Description. Adult (Figs 57–60, 74–78). Wingspan 36–38 mm. Head, tegulae and patagia yellowish-white, patagia bordered with black, thorax dark yellowish-grey with brown crest; ground colour of forewing dark yellowish-brown with metallic shining, much darker than in T. glauca; basal field black, with white bordering; subbasal field dark yellowish-brown; antemedial line black, less waved than in T. glauca, with thin white inner borderline; medial field dark yellowish-brown with diffused medial shadow expressed as black patches in costal and ventral part of wing; orbicular as small orange-yellowish dot on black background; cell between stigmata filled with black; orbicular small, like yellow-brown or brown streak encircled with white line; small orange or yellowish dash lies from reniform towards postmedial line; postmedial line black, less dentate than in T. glauca, outlined inwardly by white contrast borderline; forming prominent white mark in costal area above reniform; subterminal field rather wide, dark yellowish-brown, with metallic shining; subterminal line less dentate and less contrast than in T. glauca, marked by bordering with brown terminal field, which forms clear whitish-brown triangular mark; between two extensions of subterminal line; terminal line as row of thin black streaks, bordered with thin orange line; cilia dark yellowish-brown, whitish opposite veins. Hindwing with deep yellow basal part and dark broad brownish-black terminal band; cilia grey-brown, pale.
Male genitalia (Fig. 112, 113). Male genitalia very similar to T. glauca, but slightly differ by narrower valva, higher juxta, shorter and more straight harpe, narrower aedeagus and more developed subapical fields of cornuti. Uncus short, thinner than in T. glauca, 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 higher the in T. glauca; valva relatively short, somewhat narrower than in T. glauca, with parallel margins, sacculus narrow, elongate; in apical third ventral margin of valva rounded and gradually constricted distally, apex rounded; harpe lies in distal third of valva, straight, relatively short. Aedeagus relatively short narrower than in T. glauca, 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 more developed than in T. glauca.
Female unknown.
Etymology. The specific name is given by the difficulty in identification of the species and separation it from T. glauca.
Distribution and bionomy. North India (Arunachal Pradesh), Southwest China (Provs. Yunnan: Mekong valley; Xizang=Tibet), North Thailand (Chiang Mai). The species occurs in secondary and primary forest at elevation 2000–2400 m. Moths fly in May and August.
