Diagnosis. Similar to T. nigrobinotatus in general aspects, T. armatusimilis can be recognized by the anterolateral margins of the pronotum concolorous with the pronotal disc; humeral angles shorter and slender, laterally directed ( Figs 20–22, 24 ); black spots on the apices of radial veins distinctly smaller than in T. nigrobinotatus ( Fig. 20 ), and lateral row of black spots on the urosternites restricted to the anterior margin of each urosternite ( Fig. 22 ); females have a well-defined rounded projection on gonocoxites XIII ( Figs 28, 29 ), secondary thickening of gonapophyses IX sickle-like ( Fig. 30 ), anterior projection of thickening of vaginal intima v-shaped ( Fig. 30 ) and capsula seminalis elliptical ( Fig. 30 ); in males, the mesial portion of ventral rim slightly concave ( Fig. 33 ), and superior process of dorsal rim of pygophore subrectangular ( Fig. 35 ). A differential diagnosis between T. nigrobinotatus and T. armatusimilis sp. nov. is presented on table 1.

Measurements: (n=10). Head length: 1.2 ± 0.10 (1.1–1.5), width: 1.6 ± 0.07 (1.5–1.7); pronotum length: 1.7 ± 0.15 (1.4–1.9), width: 5.55 ± 0.43 (4.7–6.0); scutellum length: 2.7 ± 0.19 (2.3–2.9), width: 2.45 ± 0.18 (2.4–2.8); antennomeres length: I 0.22 ± 0.05 (0.2–0.3), II 0.82 ± 0.5 (0.8–0.9), III 0.65 ± 0.5 (0.6–0.7), IV 0.6 ± 0.0 (0.6–0.6); V 0.5 ± 0.0 (0.5–0.5); labial segments length: I 0.75 ± 0.05 (0.7–0.8), II 0.85 ± 0.04 (0.8–0.9), III 0.58 ± 0.03 (0.5–0.6), IV 0.59 ± 0.08 (0.5–0.6); abdominal length: 3.97 ± 1.07 (3.2–5.8), width: 3.8 ± 0.95 (3.1–5.3); total length: 7.5 ± 0.50 (7.0–8.4).

Etymology. From armatus (Latin) and similis (Latin) in reference to T. armatus described by Thomas (1992), here considered to be a junior synonym of T. nigrobinotatus .

Distribution: Uruguay (Colonia).
