(Figs. 4, 8)
Type material. Holotype. [VIETNAM] ♂, Tam Dao [Village] (930m), 8 Jul 2003, Y.S. Bae et al. (gen. slide JBH-4545; adult photos 15921) (INUC/NIBR).
Diagnosis. This species is distinctive in the white marks of the forewing apex and the subapical bright orange-yellow bar, as well as for the straight horizontal orange-yellow line from the wing base to 1/3. The male genitalia have a very long thin uncus, and the hami are also long and thin, tapering from a bulbous base to a sickle-like acute apex; and the socii are long and thin. Viewed dorsally, this species has the labial palpi approximate to each other (see Fig. 4), while in the other species the palpi are further apart (Figs. 1–3).
Description. Wing expanse: 12mm (n = 1).
Head (Fig. 4): brown-gray, with yellow laterally, but white on caudal eye margin and neck; antenna yellow and brown-gray, with amber venter, with long black ventral cilia in pairs; labial palpus mostly white, with yellow and brown-gray on basal segment, and apical segment with black laterally near apex; head venter white.
Thorax (Fig. 4): brown-gray, with yellow lateral line each side; tegula brown-gray with yellow margin distad; venter white; legs white with dark brown bar marks as in the other species.
Forewing (Fig. 4): black-brown, with median striae white and angled from dorsal margin toward apex; a straight light orange line along radius from base to 1/3, with a corresponding faint shorter pale white line on cubitus; costa with angled white marks from margin to radius, each bordered by black-brown and with orange between, the distad white mark more straight; wing apex with a large white wedge from costal margin to near termen and then sharply recurved back to near costa, margined by black-brown and bordered by orange; a large orange to orange-yellow curved wedge, widening from near costal margin toward termen; termen with thin orange line, interrupted below apex by a white black-margined fringe indentation; tornal quarter with series of white spots and short striae, all curved toward apex, and one larger yellowing-spot on cubitus below end of cell; subtornal orange area with four black spots, with basal two larger; fringe black-brown, with white along apex and inside termen invagination; venter dark brown, with very dull repetition of the dorsal markings, but bright orange-yellow and white dorsal marks repeated in apex and termen.
Hindwing (Fig. 4): dark brown with orange suffused cell area from midwing to near wing base; termen with orange line from apex to tornus; anal sector lightly pale brown; costal sector white; venter dark brown, with orange-yellow on termen and apex, and pale yellow thin line at end of cell.
Abdomen: lustrous bronze-brown; venter lustrous white, but sequentially less white on sternites 3–6; genital tufts brown with white ventrally and laterally; pregential segment (Fig. 8c), truncated, with medial U-shaped invagination; coremata long, from deep lateral pouches.
Male genitalia (Fig. 8): tegumen globular, rounded; uncus (Fig. 8b), very long (ca. 2/3 valval length), sclerotic and thin, from bulbous base quickly thinned and uniform to acute-round apex, overall decumbent and evenly recurved after basal bend; hami (Fig. 8b), long and thin sclerotic, from wide base and tapering distally gradually to sickle-like acute point; socii (Fig. 8b), long and thin, moderately setose; gnathos (Fig. 8b), with short lateral flattened arms, convergent medially to knobbed ends; transtilla (Fig. 8b), a thin band, somewhat arched dorsally; juxta (Fig. 8b), an ovate plate (slightly concave caudally), with dorsal margin truncated and slightly concave, laterally projected narrowly into anellus ring (partially as sclerotized band; aedeagus (Fig. 8a), short, tubular, with short caudal projection and distally blunt; phallobase obsolete; cornutus a long, thin flechette; vesica spinose; ductus ejaculatorius long, with elongate-globular hood; valva (Fig. 8), elongate, oblong with rounded termen, overall setose; sacculus slightly bulging beyond base; vinculum U-shaped quadratic (Fig. 8b has the vinculum twisted out of position and dorsad instead of ventrad); saccus obsolete.
Female unknown.
Etymology. The species is named for the hill station, Tam Dao, now included also in Tam Dao N. P., Vinh Phuc Prov.
Biology. Unknown. Flight period: July. Habitat (Fig. 11) is montane subtropical forest (Sterling et al. 2006).
Distribution. Known only from northern Vietnam.
Discussion. This species is among those species superficially resembling the generic type-species, T. zapyra from New Guinea, but the genitalia are very different. The most similar species by maculation is one from Thailand, Thaumatographa johnbradleyi (Razowski, 2009) (n. comb., originally described in Hilarographa), however, the genitalia are very different. These species form a different species-group from the previous species described herein, but all the Thaumatographa species need further study before species-groups can be assigned.
