Marçal, 1♂( MPEG 35500).   Etymology.The specific name is a noun in apposition after the typelocality.   Diagnosis.Males of  Tupirinna mutum  sp. nov.resemble those of  T. platnicki  sp. nov.by the presence of a subapical embolar reinforcement ring ( Fig. 11A), but can be recognized by the presence of a large, blunt sub-apical tegular process superposed to the embolar base ( Fig. 11A, B). Females resemble those of  T. araguaia  sp. nov.by the continuous border of the copulatory opening, but can be recognized by the smaller size of the copulatory opening and by the convex epigynal plate the posterior margin ( Figs 11C, D).   Description. Male holotype(MPEG 19945). Carapace orange, with brown stripe extending over ocular area, and dark brown lateral stripes. Chelicerae dark brown. Labium brown. Endites brown. Sternum and borders yellow, with anterior lateral excavations brown. Legs yellow, with lateral surfaces of patellae black; proximal and distal regions of lateral surfaces of tibiae black. Abdomen dorsum grey, with pair of black longitudinal spots in cardiac area; in median region a pair of black transversal spots, followed by three black transverse spots; after that, one black transverse spot and black spot close to spinnerets, venter yellow ( Fig. 4A).
