Diagnosis. Adult ( Figs 1, 2 ). Wingspan 60–65 mm. The species has odd appearance having bipectinate antennae and forewing pattern dissimilar to other species of Tambana . Forewing ground colour black-brown; wing pattern formed by pale antemedial line, black hardly traceable orbicular and reniform; white mark behind the reniforn toward thin, white antemedial line, blackish-brown subterminal line, white subapical streak and thin pale subapical line with black-brown streaks and terminal line as row of black semilunar streaks outlined with white. Hindwing yellow, with clear blackish terminal band.

Male genitalia ( Fig. 89 ). The armature of male genitalia is similar to T. bella , but differs by longer valva with longer sacculus and less curved harpe. Uncus rather broad, square-tipped; tegumen higher than vinculum; juxta broad, with rounded edges; valva constricted apically, rounded on the top; harpe strong, lies in apical third of valva. Aedeagus slightly curved, with scobinate carina; vesica tubular, projecting dorsally, without cornuti. In related species T. bella aedeagus much thinner and longer, vesica unarmed, carina bearing a patch of thin spines.

Female genitalia ( Fig. 118 ). The female genitalia of T. albiplaga differs from those of its congeners by short sclerotised ductus bursae and small membranous rounded bursae. Ovipositor with very broad papillae anales; anterior and posterior apophyses moderate and equal in length; antrum deep cup-like; ductus bursae very short; corpus bursae small, rounded.

Distribution and bionomy. North India ( Hindustan, Sikkim, West and East Ghats, Meghalaya), * Vietnam, North Thailand. Moths occur in medium-high montane forest, flight period: April and May.
