Figures 13–14 View FIGURE 13 View FIGURE 14 , 17 View FIGURE 17 , 19 View FIGURE 19

Type material. Male holotype from Santarém, Pará, Brazil [-2.45062, -54.70092], N. Abrahim coll., deposited in MPEG ( ARA)036743. Female paratypes from Santarém, Pará Brazil, ([-2.45062, -54.70092]), N. Abrahim coll., deposited in MPEG ( ARA)002411 GoogleMaps   .

Etymology. The species name is a noun in apposition that honors the Munduruku indigenous people from the state of Pará. The term “Munduruku” is used by neighboring tribes rather than the Munduruku people themselves, and it means “red ants”.

Diagnosis. Males of Bulboctenus munduruku   sp. nov. resemble those of B. itunaitata   sp. nov. by the apical projections of the MA well differentiated and the RTA enlarged ( Figs 12 View FIGURE 12 A–C, 14A–C, 16A–C, 17A–C), but can be distinguished by the apical projection of the MA elongated, strongly curved anteriorly ( Figs 14 View FIGURE 14 A–C, 17A–C), while B. itunaitata   sp. nov. presents the apical projection of the MA slightly curved anteriorly and pointing prolaterally ( Fig. 12B View FIGURE 12 ). Females of Bulboctenus munduruku   sp. nov. resemble those of B. itunaitata   sp. nov. by having the copulatory ducts separated ( Figs 12 View FIGURE 12 D–E, 14D–E, 16D–E, 17D–E) but can be distinguished by the posterior lateral projections (PLP) of the MS distally narrow and pointed, the lateral projections (LP) of the lateral sectors as wide as long, distally curved, and the copulatory ducts well separated, at least by the width of a copulatory duct ( Figs 14 View FIGURE 14 D–E, 17D–E), while B. itunaitata   sp. nov. presents the copulatory ducts relatively close to each other, the LP enlarge and straight and the PLP distally rounded ( Figs 12 View FIGURE 12 D–E, 16D–E).

Leg formula 4123. Leg spination: tibia I v2-2-2-2-2, r1, p0, II v2-2-2-2-2, r1, p1, III–IV v1-1-1-1-2, r1-1, p1-1; metatarsus I v2-2-2, r1, p1, II v2-1-1-1-1, r1-1, p1-1, III v2-2-2, r1-1-1, p1-1-1, IV v1-1-1-1-1-2, r1-1-1, p1-1-1. Palp ( Figs 14 View FIGURE 14 A–C, 17A–C): wide embolus, with rectangular base and rounded apex; median apophysis with a long apex, curved anteriorly and strongly pointed; conductor with narrow base and large apex, not covering the tip of the embolus.

Female (MPEG(ARA)002411). Total length 7.80 ( Fig. 13B View FIGURE 13 ). Carapace 3.96 long and 3.07 wide. Clypeus 0.22 high. Eye diameters: AME 0.21, ALE 0.14, SME 0.30, PLE 0.32. Leg measurements: I: femur 3.14 / patella 1.58 / tibia 2.94 / metatarsus 2.47 / tarsus 1.10 / total 11.23; II: 2.91 / 1.52 / 2.70 / 2.30 / 1.06 / 10.49; III: 2.77 / 1.33 / 2.24 / 2.49 / 1.10 / 9.93; IV: 3.60 / 1.42 / 3.15 / 4.09 / 1.42 / 13.68. Leg formula 4123. Leg spination: tibia I–II v2-2-2-2-2, r0, p0, III v1-1-1-1-2, r1-1, p1-1, IV v1-1 -1-1-2, r1-1-1-1, p1-1; metatarsus I–II v2-2-2, r0, p0, III v1-1-1-1-2, r1- 1-2, p1-1-2, IV v1-1-1-1-1-2, r1-1-1, p1-1-2. Epigyne ( Figs 14 View FIGURE 14 D–E, 17D–E): hexagonal median sector with pointed posterior lateral projections, shaped like an arrow; lateral projections of the lateral sector short, as wide as long; straight copulatory ducts; small fertilization ducts.
