Etymology. The specific name is a noun in apposition taken from the Brazilian language that is used to denote a Manaus origin.

Diagnosis. Guadana manauara   sp. nov. is distinguished from the remaining species of the genus by the male palp RTA with dorsal branch wide and slightly twisted distally and ventral branch truncated at tip, by the bulb with a bifid embolus with wide and rectangular base and long and slender tips ( Fig. 13 View FIGURES 13–19 ), by the female epigynum with epigynal ledges transversal and fused ( Fig. 17 View FIGURES 13–19 ) and by the vulva with rounded spermathecae ( Fig. 18 View FIGURES 13–19 ).

Description. Male (IBSP 9163): Dorsal shield of prosoma yellow with pale brown markings laterally. Eye area slightly darker. Chelicerae pale yellow with brown spot at base. Pedipalps pale yellow. Legs pale yellow with brown spots at the base of spines. Sternum cream colored with pale brown markings. Labium and endites cream colored. Opisthosoma yellow. Dorsally with two pairs of round, orange muscular impressions. Laterally mottled with white spots and covered with dark hairs ( Fig. 1 View FIGURES 1–6 ). Total length 7.1. Prosoma: 3.0 long, 3.0 wide. Opisthosoma: 3.7 long, 2.8 wide. Eye diameters: 0.22, 0.22, 0.14, 0.22; interdistances: 0.10, 0.02, 0.24, 0.24, 0.26, 0.22. Legs: I: 24.5 (6.3, 1.6, 7.0, 7.0, 2.6); II: 27.6 (7.0, 1.7, 8.1, 8.0, 2.8); III: 17.3 (4.8, 1.3, 4.7, 4.9, 1.6); IV: 19.7 (5.2, 1.2, 5.1, 6.2, 2.0). Spination follows the generic pattern, except tibia IV: d-1-0-1; metatarsus III: p1-1-1; r1-1-1. Palp: VTA triangular; DTA smooth; embolus curved prolaterally; conductor laminar and hyaline, distally involving tip of the embolus ( Figs 13–14 View FIGURES 13–19 ).

Female ( MCN 22017 View Materials ): Coloration pattern as in male ( Fig. 2 View FIGURES 1–6 ). Total length 6.8. Prosoma: 2.9 long, 3.0 wide. Opisthosoma: 3.5 long, 2.8 wide. Eye diameters: 0.16, 0.18, 0.12, 0.22; interdistances: 0.12, 0.04, 0.26, 0.28, 0.26, 0.24. Legs: I: 16.3 (4.4, 1.6, 4.8, 4.1, 1.4); II: 17.7 (5.1, 1.6, 5.3, 4.3, 1.4); III: 12.7 (3.7, 1.2, 3.4, 3.2, 1.2); IV: 14.2 (4.0, 1.1, 3.7, 3.9, 1.5). Spination follows the generic pattern. Epigynum: epigynal field slightly wider than long; median septum longer than wide, widest posteriorly; lateral lobes with slightly triangular depressions laterally; anteriorly with pair of ill defined atria with lateral copulatory openings ( Fig. 17 View FIGURES 13–19 ). Vulva: copulatory ducts long and slender, extending transversally towards each other then posteriorly to small rounded spermathecae; fertilization ducts short and hook-shaped, pointing anteriorly ( Figs 18–19 View FIGURES 13–19 ).

Variation. Males (n = 6): total length 6.3–7.1; prosoma 2.7–3.0; femur I 5.9–6.4. Females (n = 3): total length 6.8–8.1; prosoma 2.9–3.4; femur I 4.3–4.8.

Distribution. Brazil: known from Amazonas and Acre ( Fig. 39 View FIGURE 39 ).
