Mago vicanus Simon, 1900: 57 (Male lectotype designated by M.E. Galiano from S„o Paulo de Olivença, Amazonas, Brazil, de Mathan leg., deposited in MNHN, not examined); Galiano, 1963: 394, pl. XXVII, figs 1–3.

Matinta vicana: Ruiz et al., 2019: 136 ; World Spider Catalog, 2023.

Note. The species was identified using Galiano’s (1963) illustrations of the lectotype.

Material examined. BRAZIL: Amazonas: Juruá, Tamaniquá, Lago Tamaniquá (2.734⁰S 65.725⁰W): 1 ♁, 19.IX.2003, F.N.A.A. Rego et al. leg. ( IBSP 98224 ) .

Diagnosis. The male of M. vicana is similar to those of the species within the vicana species-group, especially those of M. silvae , M. fonsecai and M. pereirae for having no mastidia, a bump on the retrolateral, proximal portion of palpal tibia, and the prolateral portion of tegulum (embolus base) strongly asymmetrical proximally when compared to retrolateral portion. It can be distinguished from those of M. fonsecai and M. silvae for not having a bifid embolus tip, and from M. pereirae for having the embolus tip more slender ( Figs 32 , 44 ).

Description. Male ( Figs 25–26 ). Total length: 4.38. Carapace light brown, with white scales behind fovea and between posterior lateral and median eyes, 2.42 long, 1.78 wide and 1.24 high. Ocular area 1.41 long. Anterior eye row 1.54 and posterior 1.52 wide. Chelicera dark brown, with no mastidion or frontal keel, with paracondylic projection and projection on fang ( Fig. 76 ); PMT: 2, RMT: 5, PIMT: 3, RIMT: 3; intermarginal area with keel ( Fig. 87 ). Palp ( Figs 31–33 , 44 , 50 , 60 ) light brown. Sternum yellow. Legs 3421; I: light brown; II–III: femur proximally yellow and distally dark brown, other articles yellow; IV: brown. Leg length I 7.20 (femur: 2.34; patella: 1.07; tibia: 1.87; metatarsus: 1.25; tarsus: 0.67); II 10.01 (3.80; 1.39; 2.20; 1.54; 1.08); III 12.22 (4.44; 1.82; 2.72; 2.08; 1.16); IV 10.47 (2.02; 1.35; 2.92; 2.70; 1.48). Leg spination: femur I d1-1-1, p0-0-2, r0; II–IV d1-1-1, p0-0-2, r0- 0-1; patella I–II p1; III–IV p1, r1; tibia I v2-2-2, p1-0-0, r0; II v2-2-1r, p1-1-0, r0; III v1p-0-2, p1-1-1, r1-1-1; IV v0-1p-2; p1-1-1, r1-1-1; metatarsus I–II v2-2; III v2-2, p1-0-2, r1-0-2; IV v2-2, p1-0-2, r1-1-2. Abdomen dorsally cream-colored, with dark brown irregular mark ( Fig. 25 ); ventrally with three thin longitudinal dark brown stripes, which join at the distal part of the abdomen ( Fig. 26 ). Spinnerets brown.

Female. Unknown.

Distribution. Known only from the state of Amazonas ( Brazil).
