Type material. Male holotype from Usina Hidrelétrica Guaporé (15°07’00”S, 58°58’00”W), Vale São Domingos and Pontes de Lacerda, Mato Grosso, Brazil, 08.X.2002, I. Knysak coll., deposited in IBSP 1569 .

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. 8D ), absence of a lateral row of macrosetae in the gonocoxae, in mesal view ( Fig. 8D ) and prefemoral process with a more flat aspect in relation to the other species of the genus ( Fig. 8E ).

Description. Male (Holotype, IBSP 1569). Coloration (long-preserved in 70% ethanol): Head and antennae ocher whitish. Body ocher and paranota tip with the same color as the body ( Figs8A–C ). Legs ocher whitish. Telson ocher. Total length: 47.78. Total width: 7.06. Collum, length 2.07, width 6.69. Antennomere lengths (1>7): 0.60; 1.34; 1.39; 1.26; 1.44; 1.37; 0.20. Podomeres lengths (1>7): 0.67; 1.00; 1.96; 0.848; 1.09; 1.48; 0.47. Gonopod aperture, length 1.23, width 2.08. Telson, length 1.07. Gonopod: length 2.00, width 1.65. Gonocoxae: length 0.74, width 1.03. Telopodite: length 1.98, width 0.63. Prefemoral region 1/3 the size of telopodite. Prefemoral process ( Figs 8D–F ) long and ventrally wide, presenting a dorso-basal lobe, starting from an angle of 135°, ascending parallel to the solenomere and partially covering it in ventral view, in the middle part of the process presents a short secondary process in oval form ( Fig. 8D ). Prefemoral process ending in an acute apex ( Figs 8D–E ). Solenomere long, but not reaching the apex of the prefemoral process ( Fig. 8F ). Cingulum in medial position ( Fig. 8F ). Apex of the solenomere abruptly descending ( Fig. 8D ).

Female. Unknown.

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

Etymology. The species epithet is a reference of the Brazilian folkloric character “Caipora”. According to the indigenous legend, Caipora is considered the protector of the animals and guardian of the forests. Its origin is in the Tupi-Guarani indigenous mythology and means “inhabitant of the bush” in the Tupi language. Noun in apposition.
