Note. The specimen labelled as BC ZSM Lep 58655 has been used for barcoding. Molecular distance based on the Kimura two-parameter model for COI DNA barcodes between T. burmana and its nearest species T. glauca is 5,59%; the distance between T. burmana and T. naumanni is 6,26%.

Diagnosis. Adult ( Figs 9–12 ). Wingspan 45–48 mm. The species externally is similar to T. naumanni and T. plumbea , but differs from both by bipectinate male antennae (serrate in T. naumanni and strongly pectinate in T. plumbea ), more intensive silver-grey with metallic shining colouration of forewing (grey without shining in T. naumanni or bronze-grey in T. plumbea ). It also differs from T. naumanni by having contrast white orbicular, outlined by black and from T. plumbea by less dentate ante- and postmedial lines. Hindwing colouration varies from grey with hardly traceable terminal band and discal spot to yellowish with grey dusting, with distinct terminal band and greyish-brown basal area.

Male genitalia ( Fig. 92 ). Compared with related T. naumanni and T. plumbea by broader rounded uncus, narrover constricted apically valva, short harpe and thin aedeagus with unarmed vesica. Uncus short, broad, narrower medially and extended and rounded apically; tegumen twice higher than vinculum, bearing small penicular extensions; vinculum very large, V-shaped; transtilla with broad lobes bearing small spines; juxta shieldlike, broad, valva relatively short, broad basally, curved and prominently constricted apically, bearing a patch of strong setae on the tip sacculus narrow, harpe rather short, broad, almost straight, pointed apically. Aedeagus long, thin, slightly extended apically with carina bearing a patch of strong spines; vesica tubular, with subbasal and subapical diverticula, without cornuti.

Female genitalia ( Fig. 122 ). Differs from other congeners by very small antrum and long ribbed dusctus bursae. Ovipositor quadrangular, papillae anales moderate broad; antrum very small, triangular, shallow, weakly sclerotised; ductus bursae long, moderate wide, sclerotised and ribbed; corpus bursae rounded, membranous, with small lateral extension in caudal part.

Distribution and bionomy. East, Central, Southeast and Southwest China (Provs Fujian, Hunan, Guangxi, Sichuan), Myanmar. Moths fly in February, March, April, May, June, November.
