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.

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 .
