Figures 14 , 18 urn:lsid:zoobank.org:act: 47505136-DC93-40BB-A9A8-E0821B2F7B03 Type material. Male holotype from Parque Nacional das Emas ( 18°22’01”S , 52°47’59”W ), Mineiros , Goiás , Brazil , X.1992 , M. Barroso coll., 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 type locality ( 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. Noun in apposition.
