Diagnosis. Adult (Figs 3, 4). The species is similar in appearance to T. variegata, but differs clearly by its larger size, darker brown colouration of forewing with waved dark brown orbicular and crosslines, and by presence of two white spots in the apex and base of reniform, white spot outside reniform toward subterminal line and white mark in the costal margin. Hindwing yellow, in the female with intensive brownish-grey dusting along terminal margin and in basal area.
Male genitalia (Fig. 90). Male genitalia differ from related T. variegata by longer and narrower valva with narrower sacculus and longer harpe. Uncus rather broad, blunt and rounded apically; tegumen somewhat higher than vinculum, bearing short penicular extensions; juxta shield-like, broad, with rounded edges; valva with parallel margins and elongated narrow sacculus, constricted and slightly curved in apical part, rounded on the top; harpe strong, curved, lies in apical half of valva. Aedeagus short, massive slightly curved, with scobinate carina; vesica broadly-tubular, projecting dorsally, bearing two patches of cornuti in subapical and apical parts; apical cluster smaller than subapical, formed by seven larger cornuti. Related species T. variegata well differs by longer aedeagus and broad, unarmed vesica, bearing basally a patch of flat small cornuti.
Female genitalia (Fig. 119). T. arctoides differs from other Tambana species by expressed triangular antrum, rather short ductus bursae, narrow, elongate corpus bursae and prominent sclerotised extension in joining with cervix bursae. Ovipositor quadrangular, papillae anales moderate broad; antrum triangular, weakly sclerotised; ductus bursae rather short, ribbed, sclerotised in joining with cervix bursae, which is extended and sclerotised; corpus bursae long, thin, membranous.
Distribution and bionomy. * Northwest and Southwest China (Provs Shaanxi, Sichuan), North Vietnam, * Myanmar. The species occurs in the montane forest at elevation 1500–2400 m. Moths fly in May and June.
