Barrosocoll., deposited in IBSP 1061.   Diagnosis. Adult males differ from all other species of the genus by the combination of the following characters: gonocoxae conspicuously greater than half the size of the telopodite ( Fig. 14D); absence of indentations in the prefemoral process ( Fig. 14D); absence of a secondary process of the prefemoral process and presence of a lobe in the solenomere, visible in ventral view ( Fig. 14E).   Description.Male ( Holotype, IBSP 1061). Coloration (long-preserved in 70% ethanol): Head and antennae ochre. Body ocher and paranota tip with the same color as the body ( Figs 14A–C). Legs ocher whitish. Telson ocher. Total length: 39.07. Total width: 5.57. Collum, length 2.30, width 5.19. Antennomere lengths (1>7): 0.48; 1.35; 1.10; 1.06; 0.99; 1.00; 0.24. Podomeres lengths (1>7): 0.66; 0.88; 1.50; 0.70; 0.89; 1.10; 0.33. Gonopod aperture, length 1.33, width 2.19. Telson, length 1.05. Gonopod: length 1.58, width 1.68. Gonocoxae: length 0.96, width 1.06. Gonocoxae globose, about 1/2 the size of the telopodite. Telopodite: length 1.44, width 0.74. Prefemoral region short, 1/3 the size of telopodite. Prefemoral process long and falciform, presenting a dorso-basal lobe, starting from an angle of 225°, involving the solenomere in its initial portion, subsequently ascending parallel to the solenomere and partially covering it in ectal view ( Figs 14D–F). Solenomere long and falciform, not reaching the apex of the prefemoral process ( Fig. 14E). Cingulum in basal position ( Fig. 14F). Median portion of the solenomere with a rounded lobe, visible in ventral view ( Fig. 14E). Apex of the solenomere sickle-shaped ( Fig. 14E). Female. Unknown.   Distribution.Known only from the typelocality ( Fig. 18).   Etymology.The species epithet is a reference of the Brazilian folkloric character “Boitatá”. According to the indigenous legend, Boitatá is a large fire serpent that protects the animals and the forests from people who try to burn the vegetation.
