Etymology. The specific name refers to the locality of one of the paratypes; noun in apposition.

Diagnosis. Males of M. jaraua   spec. nov. resemble those of M. guri   spec. nov. ( Figs 162–165 View FIGURES 162–165 ) by the palp with tegulum strongly indented prolaterally and embolus C-shaped with long membranous region ( Figs 170, 172 View FIGURES 169–172 ). They are distinguished from the latter species by the RTA gradually tapering ( Fig. 171 View FIGURES 169–172 ) (RTA with rounded base abruptly narrowed medially towards tip in M. guri   spec. nov.). Females resemble those of M. kaieteur   spec. nov. ( Figs 184– 185 View FIGURES 184–190 ) by the vulva with internal ducts with FW postero-laterad, GP posteriad and SP ovoid. They are distinguished from the latter species by the MS roughly two times longer than wide, widest medially and EP with anterior margin reaching half MS lenght ( Figs 173, 176 View FIGURES 173–178 ) (MS narrow, three times longer than wide, widest posteriorly and EP with anterior margin reaching one fifth MS length in M. kaieteur   spec. nov.).

Description. Male (holotype): Total length 10.1. Prosoma 4.7 long, 4.2 wide. Opisthosoma 5.0 long, 2.3 wide. Eye: diameters: 0.42, 0.33, 0.30, 0.35; interdistances: 0.20, 0.10, 0.40, 0.43, 0.28, 0.17. Legs: I: 30.3 (8.2, 2.5, 8.6, 8.6, 2.4); II: 33.3 (9.1, 2.8, 9.6, 8.4, 2.4); III: 21.5 (6.5, 2.0, 5.8, 5.5, 1.7); IV: 24.0 (7.0, 2.0, 6.4, 6.7, 1.9). Spination follows the generic pattern, except tibiae I–II: d1-0-1. Palp: PTA triangular, as wide as long; RTA conical; subtegulum visible in ventral view between 7–9 o’clock; conductor with narrowed base ( Figs 169–172 View FIGURES 169–172 , 179–181 View FIGURES 179–183 ).

Female (IBSP 165050, paratype): Total length 12.2. Prosoma 4.7 long, 4.3 wide. Opisthosoma 7.0 long, 4.1 wide. Eyes: diameters: 0.40, 0.34, 0.26, 0.32; interdistances: 0.23, 0.13, 0.45, 0.45, 0.25, 0.20. Legs: I: 22.2 (6.2, 2.5, 6.1, 6.2, 1.2); II: 24.8 (7.1, 2.6, 6.7, 6.7, 1.7); III: 16.7 (5.1, 2.0, 4.3, 4.0, 1.3); IV: 18.9 (5.6, 1.9, 5.0, 5.0, 1.4). Spination follows the generic pattern. Epygine: EF roughly as wide as long; MAB embedded in EF; EP triangular, roughly 1.5 times longer than wide; LL touching posteriorly ( Fig. 173 View FIGURES 173–178 ). Vulva: internal ducts with FW slender, not dilated; GP 2 times longer than wide, curving medially, arising from ducts at first turn; SP ovoid; FD antero laterad ( Figs 174–175, 177–178 View FIGURES 173–178 , 183 View FIGURES 179–183 ).

Variation. Males (n = 2): total length 10.1–13.6; prosoma length 4.7–5.6; femur I length 7.6–8.2. Females (n = 5): total length 10.9–19.4; prosoma length 4.7–7.4; femur I length 6.1–8.2. Epigyne can have MS more laterally covered by LL and EP slightly over 2 times longer than wide ( Fig. 176 View FIGURES 173–178 , 182 View FIGURES 179–183 ).

Distribution. Northwestern South America ( Suriname, French Guiana, Ecuador, Peru and Brazil) ( Fig. 316 View FIGURES 315–318 ).
