Etymology. The name is a patronym in honor of our friend and colleague, the arachnologist Regiane Saturnino (nicknamed “Regi”).

Diagnosis. Males of Tupirinna regiae sp. nov. differ from those of T. rosae by the apical spur inserted apically on ventral lobe of RTA and by the absence of a TEP; they differ from those of other species with ventral lobe of RTA not divided basally ( T. platnicki sp. nov., T. mutum sp. nov. and T. araguaia sp. nov.) by the presence of a tegular retro-apical acute projection (TRP in Fig. 9A–B ). Females resemble those of T. rosae by the copulatory duct developed anteriorly to the copulatory opening, but can be recognized by the copulatory opening represented by a transversal straight slit ( Fig. 9C ).

Description. Male holotype (MPEG 35486; Fig. 3A ). Carapace yellow, with brown median stripe extended over ocular area, and two lateral brown stripes. Chelicerae brown. Labium brown. Endites brown. Sternum yellowish-white and anterior lateral excavations brown. Legs white. Abdomen dorsum yellowish-white, with pair of black longitudinal spots in cardiac area; in median region, two pairs of black spots on each side, after which three black spots followed by one black transversal spot; venter yellowish-white.
