Type material. Male holotype from Nova Xavantina (14°40’24”S, 52°21’11”W), Mato Grosso, Brazil, XI.1949, Instituto Butantan Expedition coll., deposited in IBSP 59 View Materials GoogleMaps   . Paratype: one male with the same data of the holotype, deposited in IBSP 7786 View Materials GoogleMaps   .

Diagnosis. Adult males differ from all other species of the genus by the combination of the following characters: short (about half the length of secondary processes categorized as “elongated”) secondary process of the prefemoral process ( Fig. 7D View FIGURE 7 ) and presence of a lateral row of macrosetae in the gonocoxae, in mesal view ( Fig. 7D View FIGURE 7 ).

Description. Male (Holotype, IBSP 59). Coloration (long-preserved in 70% ethanol): Head and antennae ochre. Body ocher with the edge of the paranota yellow whitish ( Figs 7A–C View FIGURE 7 ). Legs ocher whitish. Telson ocher. Total length: 59.40. Total width: 9.76. Collum, length 2.98, width 9.56 Antennomere lengths (1>7): 0.69; 1.85; 1.50; 1.37; 1.38; 1.55; 0.37. Podomeres lengths (1>7): 0.89; 1.33; 2.84; 1.18; 1.59; 1.99; 0.45. Gonopod aperture, length 1.55, width 3.03. Telson, length 1.68. Gonopod: length 3.17, width 1.88. Gonocoxae: length 0.90, width 1.03. Telopodite: length 3.04, width 0.90. Prefemoral region 1/3 the size of telopodite. Prefemoral process ( Fig. 7D View FIGURE 7 ) length, broad and without indentations, presenting a dorso-basal lobe, starting from an angle of 135°, ascending parallel to the solenomere and partially covering it in mesal view, in the middle part of the process presents a short trianguliform secondary process, acute apex ( Fig. 7D View FIGURE 7 ). Solenomere long and narrow ( Fig. 7F View FIGURE 7 ). Cingulum positioned centroposteriorly ( Fig. 7F View FIGURE 7 ). Apex of the solenomere acute and abruptly descending ( Fig. 7F View FIGURE 7 ).

Female. Unknown.

Distribution. Known only from the type locality ( Fig. 11 View FIGURE 11 ).
