Type material. Male holotype from Fazenda Sandoval , Porto Nacional (10°42’30”S, 48°25’01”W), Tocantins, Brazil, 28.XI.2013, A. Chagas-Jr and A. Giupponi coll., deposited in IBSP 7600 . Paratype: one male with the same data of the holotype, deposited in CZUFMT 838 .

Diagnosis. Adult males differ from all other species of the genus by the combination of the following characters: absence of indentations in the prefemoral process ( Figs 15D); prefemoral process not reaching the apex of the solenomere ( Figs 15D–F) and the prefemoral process not completely involving the solenomere, in ectal view ( Figs 15E–F).

Description. Male (Holotype, IBSP 7600). Coloration (long-preserved in 70% ethanol): Head ocher, with area around the antennae and the dorsal groove of the head with brownish coloration. Antennae ocher with the dorsal region of each antennomere presenting brown coloration, the seventh antennomere totally brownish. Body presenting metazonite with its anterior portion reddish brown and the posterior portion yellowish whitish, prozonite presenting the anterior portion whitish yellow and the posterior portion brown reddish ( Figs 15A–C). Legs whitish yellow. Telson whitish yellow. Total length: 51.57. Total width: 8.31. Collum, length 2.93, width 8.00. Antennomere lengths (1>7): 0.69; 1.63; 1.65; 1.50; 1.58; 1.40; 0.30. Podomeres lengths (1>7): 0.83; 1.63; 2.35; 0.97; 1.18; 1.44; 0.50. Gonopod aperture, length 1.42, width 2.91. Telson, length 0.97. Gonopod: length 2.33, width 1.75. Gonocoxae: length 0.83, width 1.05. Telopodite: length 2.23, width 0.78. Prefemoral region 1/3 the size of telopodite. Prefemoral process as a short blade, elliptical and acute, presenting a dorso-basal lobe, starting from an angle of 180°, ascending parallel to the solenomere and partially covering it in mesal view ( Figs 15D–E). Solenomere long, broad in the middle portion due to the presence of the cingulum and narrowing at apex zone ( Figs 15D–E). Cingulum in medial position ( Fig. 15F). Apex of the solenomere sickle-shaped ( Figs 15E–F).

Female. Unknown.

Distribution. Known only from the type locality ( Fig. 18).
