Diagnosis. Adult males differ from all other species of the genus by the combination of the following characters: presence of a secondary process at the apex of the prefemoral process ( Figs 23D View FIGURE 23 ); absence of a lateral expansion in the solenomere ( Figs 23D–E View FIGURE 23 ) and the prefemoral process involving the solenomere, in ectal view ( Fig. 23F View FIGURE 23 ).

Description. Male (Holotype, IBSP 1699). Coloration (long-preserved in 70% ethanol): Head reddish brown with the labrum yellowish. Antennae reddish brown. Body reddish brown with the edges of the paranota whitish ( Figs 23A–C View FIGURE 23 ). Legs ocher whitish. Telson reddish brown. Total length: 59.44. Total width: 9.64. Collum 3.04 length, 8.85 width. Antennomere lengths (1>7): 0.72; 1.68; 1.52; 1.78; 1.73; 1.44; 0.29. Podomeres lengths (1>7): 0.92; 1.25; 2.30; 0.95; 1.21; 1.56; 0.55. Gonopod aperture 1.70 length, 3.03 width. Telson 1.82 length. Gonopod: 3.15 length, 2.25 width. gonocoxae: 1.00 length, 1.27 width. Telopodite: 3.09 length, 0.95 width. Prefemoral region short, 1/4 the size of telopodite. Prefemoral process ( Figs 23D–F View FIGURE 23 ) long and narrow, presenting a dorso-basal lobe, starting from an angle of 180°, involving the solenomere in its initial portion, subsequently ascending parallel to the solenomere and partially covering it in ectal view, apex dividing into two acute projections ( Fig. 23D View FIGURE 23 ). Solenomere long, but not reaching the apex of the prefemoral process ( Fig. 23D View FIGURE 23 ). Cingulum in basal position ( Fig. 23F View FIGURE 23 ). Apex of the solenomere sickle-shaped with sigmoid curvature ( Fig. 23D View FIGURE 23 ).

Female (Paratype, IBSP 1699). Body as in male. Total length: 69.15. Total width: 9.62. Collum 3.43 length, 9.60 width. Antennomere lengths (1>7): 0.72; 2.00; 1.77; 1.51; 1.61; 1.44; 0.42. Podomeres lengths (1>7): 0.92; 1.12; 2.22; 1.00; 1.13; 1.60; 0.49. Telson 1.47 length. Epigyne rounded with regular edges. Vulvae ( Figs 27A–B View FIGURE 27 ): 1.50 length, 0.70 width. External valve: 1.16 length, 0.29 width. Internal valve: 1.04 length, 0.34 width. Operculum: 0.37 length, 0.54 width.

Distribution. Tocantins, Brazil ( Fig. 25 View FIGURE 25 ).

Etymology. The species epithet is a reference of the Brazilian folkloric character “Mapinguari”. According to the indigenous legend, the “Mapinguari” is a hairy giant with one eye on the forehead and the mouth at the navel, living in the Amazon rainforest of Brazil. Noun in apposition.
