Type material. Holotype: BRAZIL: Mato Grosso: ♂, Alta Floresta [‑9.8760, ‑56.0860], 8 August–20 September 2009, J.S. Oliveira leg. ( IBSP 246434 View Materials ) GoogleMaps   . Paratypes: BRAZIL: Mato Grosso: 1♀, Cotriguaçu, Fazenda São Nicolau (‑9.8333, ‑58.2333), 14 October 2010, A.J. Santos leg. ( UFMG 7834 View Materials ) GoogleMaps   ; 1♀, same locality as previous specimen, January 2018, G. Almeida leg. ( IBSP 233316 View Materials ) GoogleMaps   .

Etymology. The specific name refers to the Kaiabi indigenous people, whose former territory included the distribution areas of this species; noun in apposition.

Diagnosis. Males of S. kaiabi   spec. nov. resemble those of S. punicea   ( Figs 45–47 View FIGURES 45–50 ) and S. yuyapichis   spec. nov. ( Figs 83–85 View FIGURES 83–85 ) by the palp with embolus arising from tegulum at 4 o’clock position ( Fig. 14 View FIGURES 13–18 ). They are distinguished from both species by the RTA tapering and pointed ( Fig. 15 View FIGURES 13–18 ) and conductor tip barely surpassing the anterior margin of the alveolus ( Fig. 14 View FIGURES 13–18 ) (RTA roughly the same width throughout, not pointed and conductor tip surpassing the anterior margin of the alveolus by at least half its length in S. punicea   and S. yuyapichis   spec. nov.). Females resemble those of S. keyserlingi   ( Figs 27–29 View FIGURES 24–29 ) by the epigyne with MS triangular, wider than long, widest anteriorly ( Figs 16 View FIGURES 13–18 ). They are distinguished from the those of the latter species by the vulva with FW slender, slightly wider than the ducts between first and second turns (FW dilated, four times wider than ducts between first and second turns in S. keyserlingi   ) ( Fig. 17 View FIGURES 13–18 ).

Description. Male (holotype): Total length 10.3. Prosoma: 5.0 long, 5.1 wide. Opisthosoma: 5.0. Long, 3.0 wide. Eyes: diameters: 0.40, 0.34, 0.25, 0.30; interdistances: 0.35, 0.22, 0.55, 0.55, 0.37, 0.25. Legs: I: 29.7 (8.0, 3.0, 8.1, 8.5, 2.1); II: 31.6 (8.5, 3.1, 8.7, 9.0, 2.3); III: 21.8 (6.5, 2.5, 5.5, 5.7, 1.6); IV: 24.3 (7.1, 2.4, 6.2, 6.7, 1.9). Spination follows the generic pattern, except tibia II: d1-0-1 and patella III: p0. Palp: RTA two times longer than wide, disto-ventrad in retrolateral view; PTA triangular, as wide as long; subtegulum not visible in ventral view; tegulum rounded; conductor 1.5 times longer than wide; roughly the same with throughout ( Figs 13–15 View FIGURES 13–18 , 19–21 View FIGURES 19–23 ).

Female (IBSP 233316, paratype): Total length 17.8. Prosoma 6.8 long, 6.3 wide. Opisthosoma 10.8 long, 7.0 wide. Eyes: diameters: 0.55, 0.46, 0.34, 0.42; interdistances: 0.43, 0.25, 0.70, 0.70, 0.40, 0.28. Legs: I: 29.0 (8.2, 3.1, 7.6, 8.0, 2.1); II: 30.8 (8.8, 3.4, 8.1, 8.4, 2.1); III: 22.6 (6.8, 2.7, 5.8, 5.5, 1.8); IV: 25.1 (7.4, 2.7, 6.3, 6.7, 2.0). Spination follows the generic pattern. Epigyne: EF wider than long; MAB embedded in EF ( Fig. 22 View FIGURES 19–23 ); LL touching each other posteriorly; TP roughly two times wider than long ( Figs 16 View FIGURES 13–18 , 22 View FIGURES 19–23 ). Vulva: internal ducts with FW posteromediad; GP short, rounded, emerging from ducts at second turn; SP spherical; FD laterad ( Figs 17–18 View FIGURES 13–18 , 23 View FIGURES 19–23 ).

Variation. Females (n = 2): total length 15.4–17.8; prosoma length 6.8–7.2; femur I length 8.2–8.6.

Distribution. Known from northern state of Mato Grosso, Brazil ( Fig. 90 View FIGURES 89–90 ).
