Type material. Holotype: male from PPBio plot, Igarapé Caquajó , Floresta Nacional de Caxiuanã, Portel, Pará, Brazil (1.96055556°S 51.61255556°W), 12.V.2005, C.A. Lopes leg. ( MPEG 34243 ).

Additional material examined. BRAZIL, Pará: Rio Xingu, Vitoria do Xingu (2.70861111°S 52.09111111°W), 03–12.IX.2000, C. Maciel leg. ( MPEG 34244 ).

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 ); 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 ). 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 ); ventrally pale, darker in the middle ( Fig. 19 ). Anterior and median spinnerets pale; posterior brown. Female. Unknown.

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