Etymology. The species name is a toponym in apposition referring to the type locality. It is a word in the Quechua language meaning “mud”.

Diagnosis. Males of Acanthoctenus torotoro sp. nov. ( Figs 48 View FIGURE 48 D–E, 49) resemble those of A. manauara sp. nov. ( Figs 44 View FIGURE 44 D–E, 45A–B) by the palpal tibia elongated, at least 2.5 times longer than wide, and RTA elongated, longer than wide. It can be distinguished by the embolus straight, not bended basally. A. manauara sp. nov. presents a basally bended embolus.

Description. Male (holotype UFMG 22307). Total length 8.32. Carapace 3.98 long and 3.34 wide. Clypeus 0.15 high. Eye diameters: AME 0.26, ALE 0.17, PME 0.27, PLE 0.35. Leg measurements: I: femur 6.51/ patella 2.01/ tibia 7.53/ metatarsus 6.78/ tarsus 2.00/ total 24.83; II: 5.37/ 1.99/ 5.16/ 4.94/ 1.58/ 19.04; III: 4.32/ 1.57/ 3.80/ 4.45/ 1.49/ 15.63; IV: 6.11/ 1.55/ 5.25/ 7.25/ 2.23/ 22.39. Leg formula 1423. Leg spination: tibia I and II v-2-2-2- 2-2-2-2-2-2, p-1-0-1-1, r-0-1-1-0, III v-2-2-2, p-1-1, r-1-1-1, IV v-2-2-2, p-1-1, r-1-1; metatarsus I, II v2-2-2-2-2, p-1-1, r-1, III v-2-2-2, p-1-1-1, r-1-1, IV v1-1-1-1-1, p1-1-, r-1-1-1. Palp ( Figs 48 View FIGURE 48 D–E, 49): tibia shorter than cymbium, slightly curved; RTA elongated with bifid tip; cymbium elongated and with retrobasal projection; embolus elongated, cylindrical, and bent; conductor hyaline and following the tip of embolus; median apophysis laminar, elongated, narrow at the base and wider at the top, with a proapical hook and retrolateral ridge.
