Description. Measurements: CL: 1.5; CW: 1.5; DSL: 5.5; DSW: 4.4; Fe: 2.8, 6.0, 4.4, 5.3; Pa: 0.7, 1.0, 1.0, 1.4; Ti: 2.0, 5.0, 2.4, 3.7; Mt: 3.1, 6.0, 4.2, 6.2.
diagnosis
Diagnosis. Dorsal scutum elongated β-type. Smooth ocularium. Color pattern typical easel formed by a compact equuleus. Area III of dorsal scutum with a pair of minute tubercles. Anal operculum with a low and blunt protuberance. A single dorso-apical apophysis on coxa IV. Femur IV retrolaterally armed with four prominent tubercles, the medial pair longer and acuminate (spine-shaped). Comparisons: Taito mayoruna spec. nov. can be differentiated from T. galaga, T. honda, T. kakera, T. medinae, T. osmari, T. rorschachi, T. unapuntatus, T. litteratus and T. curupira spec. nov. by presenting a typical easel on the dorsal scutum. With regard to remaining species of Taito, which share the same type of color pattern, T. mayoruna spec. nov. can be distinguished from T. insperatus, T. juruensis, T. oblongatus, T. serriperna and T. kawaiikei by presenting a protuberance on anal operculum (which is absent in species previously mentioned); and from T. spaceinvaders by the shape of that protuberance on the anal operculum, that is slightly bifid in T. spaceinvaders, and not bifid in T. mayoruna spec. nov.; by armature of femur IV which is present only retrolaterally in T. mayoruna spec. nov. and by the absence of armature on tibia IV in T. mayoruna spec. nov. Finally, this new species is differentiated from T. adrik by armature of patella IV (unarmed in T. mayoruna spec. nov.) and by armature of femur IV which is formed by five retro-distal spines in T. adrik and only two in T. mayoruna spec. nov.
