Tambana sp.

( Figs 40 , 104 )

Material examined. MYANMAR, 1 male, Prov. Kachin, road Pan Wa to Phemaw, 2260 m, 25°718′N, 98°660′E, Löffler, Naumann & Langer leg., 9–30.ix.2010, slide GB 7401m, BC ZSM Lep 48894, coll. AB. The specimen labelled as BC ZSM Lep 48894 has been used for barcoding.

Note. Beside the examined and barcoded holotype specimen of T. xilinga , we examined an additional specimen from Myanmar with molecular distance based on the Kimura two-parameter model for COI DNA barcodes between examined specimen and the nearest species T. xilinga is 0,15%. The distance between examined specimen and T. mekonga is 3,63%. The specimen is not included to the type-series of T. xilinga , it is referred in the article as Tambana sp.

Diagnosis. Adult ( Fig. 40 ). Wingspan 42 mm. The examined specimen is close to T. xilinga and T. mekonga , with main element of forewing pattern like in T. mekonga , but differs from both by larger wingspan, well expressed metallic shining; more distinct crosslines and more expressed bronze-whitish dusting on forewing. The main elements of the forewing pattern of T. sp. are closer to T. xilinga by the broader medial area, less waved subterminal line and the paler ground colour. Hindwing differs by more expressed yellow colouration and by narrower and well defined brownish-grey terminal band.

Male genitalia ( Fig. 104 ). By male genitalia this specimen is closer to T. mekonga rather than to T. xilinga sp. n. Uncus relatively short, beak-like, with small apical hook, like in T. mekonga ; tegumen broad, almost equal to vinculum by length, without penicular extensions; vinculum V-shaped; transtilla with broad leave-like lobes; juxta shield-like, broad; valva moderate large, broad basally, gradually constricted apically and rounded in the apex; costa with small protuberance opposite base of harpe. Aedeagus relatively short, thick, slightly curved medially; carina broad, sclerotised, finely scobinate; vesica broadly-tubular with subapical twin patch of moderate cornuti and subapical row of small cornuti.

Female unknown.

Distribution and bionomy. Northeast Myanmar. The moth was collected in September at elevation 2260 m.
