Etymology. The epithet, a noun in apposition, refers to the developed RvTA of the male palp.

Diagnosis. This species seems to be closely related to Mago opiparis Simon, 1900   and Mago steindachneri (Taczanowski, 1878)   , with whom it shares a spade-shaped RTA. The male of M. apophysis   sp. nov. differs from those two species by having a large RvTA placed proximally at the tibia (Figs 24–25) (RvTA near the RTA in M. opiparis   and poorly developed in M. steindachneri   ; see Galiano 1963: pl. 26, fig. 13; pl. 27, fig. 5).

Description. Male (holotype). Total length: 5.35. Carapace orange, cephalic area darker, with a few white scales around fovea ( Fig. 18 View FIGURES 18 – 19 ); 2.71 long, 1.95 wide, 1.76 high. Length of ocular quadrangle: 1.76; anterior eye row 1.96 wide, posterior 1.87 wide. A central tuft of white scales above AME and a pair of tufts of white scales connecting anterior and posterior eyes ( Fig. 18 View FIGURES 18 – 19 ). No eyebrow or clypeal tuft. Chelicera orange, with poorly developed mastidion at same location as in Mago jurutiensis Patello & Ruiz, 2014   (see Patello & Ruiz 2014: figs 6, 17–18); two promarginal and six subpromarginal teeth, the most apical promarginal overlapping the most basal subpromarginal, and one retrolateral plurident with five cusps; no modification on fang. Palp yellow; RTA with acute dorsal tip (Fig. 25); rounded tegulum and thin embolus (Fig. 24); subtegulum projected from beneath tegulum to retrolateral border of bulb (Fig. 25). Sternum yellow. Leg I brown, II –IV yellow. Leg formula: 3412. Length of femur I: 1.61; II: 1.36; III: 2.05; IV: 1.84; patella + tibia I: 2.09; II: 1.62; III: 1.79; IV: 1.60; metatarsus + tarsus I: 1.36; II: 1.37; III: 1.80; IV: 2.08. Abdomen poorly preserved; pale with two dorsal longitudinal interrupted brown lines ( Fig. 18 View FIGURES 18 – 19 ); ventrally pale, darker in the middle ( Fig. 19 View FIGURES 18 – 19 ). Anterior and median spinnerets pale; posterior brown. Female. Unknown.

Distribution. Known only from upper central state of Pará, Brazil ( Fig. 26 View FIGURE 26 ).
