Note. The specimen labelled as BC ZSM Lep 58662 has been used for barcoding. Molecular distance based on the Kimura two-parameter model for COI DNA barcodes between T. entoxantha and the nearest species T. burmana is 6,91%.

Diagnosis. Adult ( Figs 28, 29, 30 ). Wingspan 45–55 mm. Dimorphic species, female much larger than male. T. entoxantha differs from its congeners by distinct whitish or yellowish subtornal and tornal marks on blackbrown forewing and wide black-brown terminal band, much wider than in other species. Forewing pattern blackish-brown with variegate ante- and postmedial lines and with suffusion formed by whitish and bluish scales, especially in medial and subterminal fields; medial shadow dark-brown; clear yellowish tornal and subtornal mark present in tornal angle. Hindwing yellow in basal third, with wide (about two third of wing), blackish-brown terminal band.

Male genitalia ( Fig. 99 ). The male genitalia of T. entoxantha are rather different from other Tambana species. Uncus rather short, massive, rounded, tipped; tegumen broad, almost equal to vinculum, without penicular extensions; vinculum V-shaped, with saccus; transtilla with moderate lobes; juxta small, shield-like; valva relatively small compared with other Tambana , constricted distally; sacculus broad; harpe lies in distal third of valva, vertically to axis of valva, straight and strongly curved distally. Aedeagus large, rather thin, with prominent coecum, slightly curved, with long, scobinate carina; vesica bulbous-tubular, with subbasal and subapical diverticula, without cornuti.

Female genitalia ( Fig. 127 ). The female genitalia of T. entoxantha differ from other congeners by membranous triangular antrum, short sclerotised ductus bursae and weak, membranous elongate corpus bursae. Ovipositor quadrangular, papillae anales broad; anterior and posterior apophyses short, equal in length; antrum triangular, membranous, antevaginal plate separated for two small lobes; ductus bursae short, sclerotised and slightly; corpus bursae membranous, elongated sack-like, with extension in caudal part.

Distribution and bionomy. China (Jiangxi, Fujian, Hainan Isl.), India ( Hindustan, Assam, Punjab, Sikkim, Himachal Pradesh, Simla), Nepal, Thailand, Vietnam, Laos, Indonesia (Sumatra, Java). The species occurs in meso-montane forests at elevation 650–1800 m. Moths fly in January, March, April, May, June, September and October.
