Figs 29–30 , 42–43 , 49 , 55 , 78–79 , 91

Type material. Holotype: ♁ from French Guiana, Réserve Naturelle National de la Trinité (4.583⁰N 53.3⁰W), 25.X.2008, C. Courtial leg. ( MNHN).

Etymology. The epithet is given in apposition honoring the giant spider present in Harry Potter’s series.

Diagnosis. The male of M. aragog is similar to those of the species within the vicana species-group, especially those of M. maddisoni for having mastidia, separate prolateral cheliceral teeth, a bump on the cheliceral fang and a more symmetrical palpal bulb. It can be distinguished from M. maddisoni for having the bifid embolus tip ( Figs 42 , 49 ) and a triangular RTA in retrolateral view ( Figs 43 , 55 ; squared in M. maddisoni ).

Description. Male ( Figs 29–30 ). Total length: 6.02. Carapace dark reddish-brown, 3.11 long, 2.27 wide and 1.63 high. Ocular area 1.27 long, with white scales between posterior lateral and median eyes. Anterior eye row 1.92 and posterior 1.74 wide. Chelicera dark brown, with a mastidion and a bump on the fang ( Figs 78–79 ); PMT: 2, RMT: 5, PIMT: 4, RIMT: 1 ( Fig. 91 ). Palp ( Figs 42–43 , 49 , 55 ) light brown. Sternum yellow. Legs 1324; I: dark brown; II–III: femur proximally yellow, distally dark brown, other articles dark brown; IV: brown. Leg length: I 6.72 (femur: 2.06; patella: 0.88; tibia: 1.90; metatarsus: 1.10; tarsus: 0.78); II 5.56 (1.72; 1.02; 1.38; 0.82; 0.62); III 6.33 (2.23; 1.00; 1.33; 1.17; 0.60); IV 5.47 (1.70; 0.70; 1.27; 1.19; 0.61). Leg spination: femur I d1-1-1, p0-1-2, r0-0-2; II d1-1-1, p0-0-2, r0-0-2; III d1-1-1, p0-1-2, r0-0-1; IV d1-1-1, p0-0-1, r0-0-1; patella I–II p0-1-0; III–IV p0-1-0, r0-1-0; tibia I v2-1r-2, p1-0-1, r0; II v1r-2-2, p1-0-1, r0; III v2-0-2, p1-0-0, r1-1-1; IV v1p-0-2; p1-0-0, r1-1-1; metatarsus I–II v2-2; III v2-0-2, p2-0-2, r2-0-2; IV v0-2, p2-0-2, r1-1-2. The dorsal region of the abdomen cream-colored with sparse dark brown markings ( Fig. 29 ); ventrally with wide longitudinal dark brown stripe ( Fig. 30 ). Spinnerets brown.

Female. Unknown. Note. Matinta fasciata (Mello-Leit„o, 1940) was described from Guyana, near the border with Venezuela. Given the distance between the two type localities, separated by 700–800 km, and the more conspicuous abdominal pattern in M. fasciata (see Mello-Leit„o 1940: fig. 25), we are describing the male of M. aragog as a new taxon. Distribution. Known only from type locality (French Guiana).
