Diagnosis. T. annamica stumpfi is similar to the nominate T. a. annamica but differs by duller and paler, grey ground colour of forewing, more coarse wing pattern, predominantly black, without, or with weak whitish bordering crosslines and by grey-brownish, without yellow dash colour of hindwing,

Description. Adult ( Figs 65–68, 84–88 ). Wingspan 31–33 mm. Head, tegulae and patagia whitish, patagia bordered with black, thorax whitish, with brown crest; ground colour of forewing grey or pale brownish-grey without shining; basal field filled with yellowish-white, basal line marked as black streak; antemedial line black, usually less waved than in T. a. annamica , with thin diffused whitish inner border; medial field greyish-brown with diffused blackish medial shadow forming prominent black patch on costal area and between orbicular and reniform stigmata (it some specimens blackish patch not expressed); orbicular as white dot on blackish surrounding; reniform as blackish vertical streak with white bordering; whitish dash lies outward reniform to submedial line; the last is less prominent and less dentate than in T. indeterminata and T. a. annamica ; subterminal field greyish with short blackish streaks along veins; subterminal line black, dentate, stronger than in T. a. annamica outlined with diffused whitish line outwardly, with prominent whitish spot between two extensions of subterminal line; cilia grey between veins, whitish opposite veins. Hindwing uniformly grey, in some specimens pale in central part with hardly traceable whitish or yellowish patch in centre of wing and with whitish tornal mark; cilia grey with whitish.

Male genitalia ( Figs 116, 117 ). The male genitalia of T. a. stumpfi are very close to T. a annamica , small differences found in proportions of valva, stronger penicular extension and the shape of vesica. Uncus relatively short, thin, curved; tegumen broad, shorter than vinculum, with prominent penicular extensions; vinculum broadly V-shaped; transtilla with broad leave-like lobes; juxta shield-like, broad and high; valva with parallel margins, sacculus rather narrow, elongate, in apical third ventral margin of valva gradually constricted distally, apex rounded; harpe lies in distal third of valva, almost straight, relatively short. Aedeagus relatively short, not extended distally, somewhat shorter and narrower than in T. a. annamica ; carina sclerotised; vesica broadly-tubular, very big bearing large basal diverticulum covered with field of small spines and large subapical diverticulum covered with field of small spines and two smaller diverticula bearing two patches of small dense cornuti.

Female unknown.

Etymology. The subspecies name is dedicated to Johann Stumpf, German Noctuidae collector and good colleague of the authors.

Distribution and bionomy. Northwest and Southeast China (Provs Shaanxi: Qinling=Tsinling Mts; Guangdong: Nanling Mts.; Guangxi: Dayao Shan). The moths were collected in primary forest at elevation 1700– 1900 m. Flight period March, June, September and November.
