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 View FIGURE 9 ). 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 View FIGURE 9 ).
