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).

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).

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.
