Diagnosis. Males from Masteria sabrinae n. sp. resemble those of Masteria spinosa , M. simla and M. galipote n. sp. in having a paraembolic apophysis ( Fig. 27B–C View FIGURE 27 ), but differ in having a conical tooth in the embolar base ( Fig. 27B View FIGURE 27 ). Females resemble those of Masteria manauara and M. petrunkevitchi in the unilobed spermathecae, but differ in the elongated lobe, thickened duct and apex curved to ectal side ( Fig. 27D–F View FIGURE 27 ).

Etymology. In honor of the biologist Sabrina de Souza Ferreira , the senior author`s fiancée.
