Diagnosis. Most specimens of T. f. fruhstorferi are clearly distinguished from other congeners by a complete humeral lunule, distinct basal dot, medium-sized or narrow apical dot as well as by partly pale hind tibiae and tarsi (Figs 4, 5, 83). In some specimens the humeral lunule is divided on the basal and apical portions (Fig. 85) or present only by the basal portion (Figs 1, 3, 81, 82, 84). Dark-coloured specimens of T. fruhstorferi (Figs 6, 86, 87) are differentiated from the similarly coloured T. ziyardamensis sp. n. (Fig. 12) and T. pseudovitalisi sp. n. (Figs 9–11) by the shape of aedeagus (Figs 115–125, 136–151 vs. Fig. 131 and Figs 132–135, respectively) as well as by the longer hind tarsi, especially in males (Figs 175–178).
Redescription. TL = 9.2–12.0 mm (mean = 10.5 mm, n = 45) in males, 9.8–12.8 mm (mean = 11.5 mm, n = 43) in females.
Head shining black with distinct violet reflection; orbital plates indistinctly or finely striated in posterior third; frons smooth, frontal sulci deep and slightly convergent in anterior 2/3, shallow and sharply divergent in posterior third. Mandibles brown or light-brown underside, pale-yellow in basal half of topside, with light-brown teeth and apical molar. Labial palpi pale-yellow except brown apical palpomere; maxillary palpi brown except yellowish palpomeres 1 and 2. Antennae do not extend posteriorly to the shoulders, scape pale anteriorly, brownblack posteriorly, in some females entirely dark-brown or black; antennomeres 9 and 10 with protruding downward anterior lower margins, more distinct in males (Figs 29–32). Labrum varies from sub-quadrate to slightly transverse, LW/LL = 0.94–1.14 (mean = 1.05, n = 88), from dark-brown to black with large or medium-sized yellow central spot usually not extending to the border of the central apical teeth in males but to the border in females (Figs 50–54), in some females central labral spot small and dark brown (Fig. 55).
Pronotum as wide as long, PW/PL = 0.92–1.1 (mean = 1.03, n = 88), shining black-blue with violet reflection, apical lobe slightly wider in middle part; thorax black-blue with violet reflection.
Fore femora pale-yellow with brown violet-tinged posterior side and apices, middle femora pale-yellow with brown anterior side and light violet tinge, hind femora bicoloured, pale-yellow or light brown in basal half or third and black with blue tinge in apical half or 2/3; tibia often pale-yellow with brown-black apices or apical half, sometimes light brown, dark brown or even entirely black with light blue tinge; tarsomeres 1 and 2 or only tarsomere 1 of all legs in most specimens pale-yellow with brown apices, other tarsomeres dark-brown or black, in some specimens two basal tarsomeres brown with dark-brown apices and brown-black other tarsomeres, sometime only first fore and middle tarsomeres or only fore-tarsomere dark-brown while others including all hind tarsomeres black, rarely all tarsomeres black; HTbL/HTaL = 1.15–1.33 (mean = 1.22, n = 77) (Figs 175, 176).
Elytra indistinctly divergent towards apex; EL/EW = 1.86–2.09 (mean = 1.98, n = 71); EL/PL = 3.14–3.57 (mean = 3.37, n = 45) in males, 3.14–3.75 (mean = 3.48, n = 42) in females; brown-black or black with violet or blue-violet reflection; punctuation deep and regular between basal hump and central dot, then shallow and sparse, apical quarter virtually smooth; scutellum dark-brown or black with blue tinge, apical margin shortly cut. Elytral pattern presented by relatively large or dramatically small yellow or light brown humeral lunule complete in one specimens (Figs 4, 5, 83) or divided on basal and apical portions in others (Fig. 85), sometimes apical portion undeveloped (Figs 1, 3, 81, 82, 84, 86, 87), by yellow basal dot well developed in most specimens (Figs 1, 3–5, 81–85) and barely visible to absent in others (Figs 6, 86, 87), by transverse slightly oblique central dot (Figs 1, 3–6, 81–87), as well as by narrow apical dot along elytral margin (Figs 3–5, 83, 85), in some specimens only by thin yellow, yellow-brown (Figs 1, 81, 82, 84, 87) or rarely dark-brown (Figs 6, 86) apical edge.
Aedeagus in most specimens with moderately long and narrow slightly sinuate rounded apex (Figs 115–118, 120–125, 136, 137, 139, 141–149, 151), in some specimens with very thin (Fig. 150) or dramatically short blunt apex (Figs 119, 138, 140) without lateral carinae; AL = 2.4–3.0 mm (mean = 2.67, n = 40), EL/AL = 2.19–2.68 mm (mean = 2.47, n = 40).
