Diagnosis. A new subspecies is distinguished from the nominotypical one by darker colouration, reduced white elytral pattern and narrower elytral apex ( Figs 7, 8 View FIGURES 1–14 , 88, 89 View FIGURES 81–98 vs. Figs 1, 3–5 View FIGURES 1–14 , 81–85 View FIGURES 81–98 ), by wider pronotum ( Figs 179, 181 View FIGURES 179–183 ), by the longer hind tarsi—mean HTbL/HTaL = 1.18 in T. f. australis ssp. n. vs. mean HTbL/HTaL = 1.22 in T. f. fruhstorferi ( Figs 179, 180 View FIGURES 179–183 ), and by the shorter aedeagus—mean EL/AL = 2.59 in T. f. australis ssp. n. vs. mean EL/AL = 2.47 in T. f. fruhstorferi ; from dark-coloured specimens of T. f. fruhstorferi ( Figs 6 View FIGURES 1–14 , 86, 87 View FIGURES 81–98 ) the new subspecies is readily distinguished by the shape of aedeagus ( Figs 115–125 View FIGURES 115–135 , 136–151 View FIGURES 136–151 vs. Figs 126–130 View FIGURES 115–135 ). From T. pseudovitalisi sp. n. the new subspecies is differentiated both by the shape and the size of aedeagus ( Figs 126–130 View FIGURES 115–135 vs. Figs 132–135 View FIGURES 115–135 ), by the narrower elytral apex ( Figs 7, 8 View FIGURES 1–14 , 88, 89 View FIGURES 81–98 vs. Figs 9–11 View FIGURES 1–14 , 90–95 View FIGURES 81–98 ), and by the longer hind tarsus ( Figs 182, 183 View FIGURES 179–183 ).
Description. TL = 10.0–12.0 mm in males (mean = 10.95 mm, n = 12), 10.0– 12.4 mm (mean = 11.42 mm, n = 12) in females.
Head shining black-blue with purple-violet reflection, especially bright on vertex, occiput and on smooth, finely or indistinctly striated in posterior third orbital plates; frons convex, semi-circular (see above), slightly downward anteriorly (see at the side), smooth or slightly rugose, frontal sulci deep and slightly convergent in anterior half or 2/3, shallow and distinctly divergent in posterior half or third. Mandibles in males brown underside, yellow or yellow-brown topside with light-brown teeth and apical molar, in females dark-brown except pale base topside. Labial palpomeres 2 and 3 yellow, palpomere 4 dark brown; maxillary palpomeres 1 and 2 yellow, yellow-brown or brown, palpomeres 3 and 4 dark brown or brown-black. Antennae do not extend posteriorly to the shoulders, scape in males yellow or yellow-brown on anterior side and dark-brown on posterior side, in females entirely black or brown-black rarely dark brown on anterior side; antennomeres 3–6 dark brown with narrow light brown apices, antennomeres 9–11 flattened; in males antennomeres 9 and 10 with slightly protruding downward anterior lower margins, antennomere 11 slightly dilated not wider than 10 one, in females antennomeres 9 and 10 slightly dilated on anterior side ( Figs 33, 34 View FIGURES 29–49 ). Labrum indistinctly transverse, LW/LL = 1.0–1.15 (mean = 1.07, n = 24), in males black-brown with medium-sized or small yellow-brown central spot bordered from central apical teeth ( Fig. 56 View FIGURES 50–57 ), in females entirely black or brown-black ( Fig. 57 View FIGURES 50–57 ), rarely with small brown central spot.
Pronotum wider than long, PW/PL = 1.0–1.13 (mean = 1.06, n = 24) ( Figs 179, 181 View FIGURES 179–183 ), shining blue with violet reflection, apical lobe with slightly narrower sides or virtually equal wide throughout; thorax shining blue with light violet reflection.
Fore and middle femora in males pale-yellow with brown violet-tinged posterior side, in females middle femora with more expanded black colour; hind femora bicolored, pale-yellow in basal half or third in males or in basal quarter in females, and black with violet tinge in other portion; fore tibiae light brown on outer sides and brown on inner sides with dark apices, middle tibiae light brown or yellow-brown with brown apices, in some specimens foreand middle tibiae dark-brown with slightly lighter basal third, hind tibiae dark brown with black blue tinged apices, rarely all tibiae dark brown or brown-black; all tarsi black with light blue tinge; HTbL/HTaL = 1.09–1.29 (mean = 1.18, n = 23) ( Figs 179, 180, 182, 183 View FIGURES 179–183 ).
Elytra subparallel, indistinctly divergent toward apex, EL/EW = 1.85–2.06 (mean = 1.97, n = 24); longer in females—EL/PL = 3.41–3.83 (mean = 3.61, n = 12) vs. 3.3–3.72 (mean = 3.45, n = 12) in males; shining blue with purple-violet reflection and narrow bright blue or golden-blue reflection along suture; punctuation deep and regular between basal humps and central dot, shallower behind it, entirely absent in apical quarter; scutellum black with greenish-blue tinge; apical margin gradually rounded. Elytral pattern presented by pale-yellow basal portion of humeral lunule and by small basal dot, in some specimens both of them very small or basal dot barely visible or absent, by elongate, slightly oblique, wide-uniformed central dot, semilunar and slightly curved towards to suture in some females as well as by very narrow dark brown apical edge ( Figs 7, 8 View FIGURES 1–14 , 88, 89 View FIGURES 81–98 ).
Aedeagus with moderately short, straight or indistinctly curved, blunt apex without lateral carinae ( Figs 126– 130 View FIGURES 115–135 ); AL = 2.5–2.8 mm (mean = 2.64, n = 12), EL/AL = 2.38–2.73 mm (mean = 2.59, n = 12).
Etymology. The name of this new subspecies is derived from the Latin, “ australis ”, meaning ‘southern’, which indicate the southern border of distribution of T. fruhstorferi at present time.
Distribution. VIETNAM: Quang Nam, Kon Tum, Gia Lai Provinces ( Fig. 184 View FIGURES 184 ).
