Type material. Holotype: male from Parque Nacional da Serra do Pardo , São Félix do Xingu, Pará, Brazil (5.877806°S 52.795389°W), 28.IV.2012, G.R.S. Ruiz et al. leg. ( MPEG 34321 View Materials ) GoogleMaps   . Paratype: female, same data as holotype ( MPEG 34322 View Materials ) GoogleMaps   .

Etymology. The epithet, a noun in apposition, is taken from the name of the park where the type specimens were collected.

Diagnosis. This species seems closely related to Mago saperda Simon, 1900   and Mago procax Simon, 1900   for having an entire tegulum (with no membranous cleft, as seen in most species of the genus; see Patello & Ruiz 2014: fig. 23). However, both M. saperda   and M. procax   have rounded tegulum and RTA with acute tip (see Galiano 1963: pl. 26, figs 11–12; pl. 27, figs 7–8), while M. pardo   sp. nov. has an elongated tegulum (Fig. 20) and RTA with rounded tip (Fig. 21). Details of the male palp of Mago chickeringi ( Caporiacco, 1954)   are still needed, but M. chickering   has a RTA curved dorsally (see Caporiacco 1954: fig. 50a), while M. pardo   has a RTA curved ventrally (Fig. 21). The epigyne of M. pardo   is similar to that of Mago steindachneri (Taczanowski, 1878)   (see Galiano 1968: fig. 59) for having copulatory openings far from the epigynal border, but can be distinguished for having a pair of separate copulatory openings (Fig. 22), as opposed to fused into an atrium, as in M. steindachneri   .

Description. Male (holotype). Total length: 5.41. Carapace orange with a trapezoid brown marking in front of fovea ( Fig. 14 View FIGURES 14 – 17 ); 3.25 long, 2.26 wide, 2.19 high. Length of ocular quadrangle: 1.50; anterior eye row 2.10 wide, posterior 1.90 wide. No eyebrow or clypeal tuft ( Figs 14–15 View FIGURES 14 – 17 ). Chelicera orange, with no mastidion, but frontal surface flattened, with keel along border; slightly expanded laterally; two promarginal teeth, a line of four minute subpromarginal teeth, not overlapping prolateral teeth, and three fused (basal) and two separate retrolateral teeth; fang unmodified. Palp yellow ( Figs 14–15 View FIGURES 14 – 17 ); hooked RTA (Fig. 21); thin embolus arising at about 10 o’clock in the left palp (Fig. 20); subtegulum projected from beneath tegulum to retrolateral border of bulb (Fig. 21). Sternum pale. All legs yellow, with brown rings on distal femora, patellae, tibiae and metatarsi ( Fig. 15 View FIGURES 14 – 17 ). Leg formula: 1432. Length of femur I: 2.08; II: 1.65; III: 2.07; IV: 2.21; patella + tibia I: 2.89; II: 2.25; III: 2.14; IV: 2.13; metatarsus + tarsus I: 2.08; II: 1.57; III: 1.80; IV: 1.95. Abdomen pale with two dorsal longitudinal interrupted black lines ( Fig. 14 View FIGURES 14 – 17 ); ventrally with three longitudinal black lines converging at middle ( Fig. 15 View FIGURES 14 – 17 ). Spinnerets brown.

Female (paratype). Total length: 7.75. Carapace as in male ( Fig. 16 View FIGURES 14 – 17 ); 3.46 long, 2.47 wide, 1.79 high. Length of ocular quadrangle: 1.60; anterior eye row 2.26 wide, posterior 2.03 wide. Chelicera yellow, with two promarginal, seven subpromarginal and five retrolateral teeth, prolateral and subpromarginal not overlapping. Palp yellow. Sternum pale. All legs yellow ( Fig. 17 View FIGURES 14 – 17 ). Leg formula: 3412. Length of femur I: 2.01; II: 1.83; III: 2.62; IV: 2.79; patella + tibia I: 2.59; II: 2.20; III: 2.56; IV: 2.12; metatarsus + tarsus I: 1.58; II: 1.52; III: 2.03; IV: 2.17. Abdomen as in male ( Figs 16–17 View FIGURES 14 – 17 ). Epigyne with long and straight copulatory ducts and small, posteriorly placed spermathecae (Figs 22–23). Spinnerets brown.
