Type material. Holotype: BRAZIL: Mato Grosso: ♀, Alta Floresta [‑9.8760, ‑56.0860], 8 August–20 September 2009, J.S. Oliveira leg. ( IBSP 246428 View Materials ). GoogleMaps

Etymology. The specific name refers to the businessman Ariosto da Riva, who in the early 70’s acquired the region currently known as Alta Floresta, to start a new settlement project; genitive case.

Diagnosis. Females of M. rivai sp. nov. are distinguished from the remaining congeners by the epigyne with MS Erlenmeyer-shaped ( Fig. 242 View FIGURES 238–244 ) and vulva with SP elongate with smooth margins ( Figs 243 View FIGURES 238–244 ). Males are unknown.

Description. Female (holotype): Total length 17.6. Prosoma 6.8 long, 6.8 wide. Opisthosoma 10.7 long, 7.5 wide. Eyes: diameters: 0.46, 0.41, 0.30, 0.36; interdistances: 0.47, 0.38, 0.84, 0.81, 0.43, 0.28. Legs: I: 27.0 (7.5, 3.3, 6.8, 7.3, 2.1); 28.6 (8.6, 3.5, 7.0, 7.5, 2.0); III: 21.0 (6.6, 2.9, 5.0, 4.9, 1.6); IV: 22.8 (7.2, 2.6, 5.4, 5.8, 1.8). Spination follows the generic pattern. Epigyne: EF wider than long; MAB elongate; MS longer than wide, widest posteriorly; HP triangular, 1.5 times longer than wide, opening at posterior margin of MS; LL touching posteriorly ( Figs 242 View FIGURES 238–244 , 248 View FIGURES 245–249 ). Vulva: internal ducts with FW antero laterad; GP slightly longer than wide, mediad, arising from ducts at first turn; FD anteriad to antero-laterad ( Figs 243–244 View FIGURES 238–244 , 249 View FIGURES 245–249 ).
