Figs 27–28 , 34–35 , 45 , 51 , 77 , 90

Type material. Holotype: ♁ from Matinha , Nossa Senhora do Perpétuo Socorro , Itacoatiara, Amazonas, Brazil (3.154⁰S 59.324⁰W), 07.XI.2003, F.N.A.A. Rego et al. leg. ( IBSP 98226 ).

Etymology. The species is named after the folkloric Matinta Pereira (or Matinta Perera ), the Amazonian famous witch.

Diagnosis. The male of M. pereirae is similar to those of the species within the vicana species-group, especially those of M. silvae , M. fonsecai and M. vicana 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. vicana for having the embolus tip stouter ( Figs 34 , 45 ).

Description. Male ( Figs 27–28 ). Total length: 5.73. Carapace dark reddish-brown, with white scales between the lateral and median posterior eyes and behind fovea, 2.97 long, 2.16 wide and 1.26 high. Ocular area 1.45 long. Anterior eye row 1.95 and posterior 1.76 wide. Chelicera dark brown, with no mastidion or frontal keel ( Fig. 77 ); PMT: 2, RMT: 4, PIMT: 3, RIMT: 4; intermarginal area with keel ( Fig. 90 ). Palp ( Figs 34–35 , 45 , 51 ) light brown. Sternum yellow. Legs 1342; I–IV: light brown, with the exception of the femora, proximally yellow. Leg length I 5.68 (femur: 1.80; patella: 0.82; tibia: 1.58; metatarsus: 0.83; tarsus: 0.65); II 4.43 (1.37; 0.74; 1.08; 0.70; 0.54); III 5.62 (2.02; 0.85; 1.20; 0.95; 0.60); IV 5.49 (1.93; 0.60; 1.16; 1.20; 0.60). Leg spination: femur I–II d1-1-1, p0-0-2, r0-0-1; III d1-1-1, p0-1-2, r0-0-1; IV d1-1-1, p0-0-1, r0-0-1; patella I–II p1-1-0; r1-0-0; III–IV p1-1-0, r1-1-0; tibia I v2-2-2, p1-0-0, r0; II v1r-2-2, p1-1-0, r0; III v1p-0-2, p1-0-1, r1-1-1; IV v1p-0-2; p1-0-1, r1-1-1; metatarsus I–II v2-2; III v2-0-2, p1-0-2, r1-0-2; IV v2-0-2, p1-0-1, r1-1-2. Abdomen dorsally cream-colored ( Fig. 27 ); ventrally with wide longitudinal dark brown stripe ( Fig. 28 ). Spinnerets brown.

Female. Unknown.

Distribution. Known only from type locality (Amazonas, Brazil).
