Etymology. The specific name refers to the type locality; noun in apposition.

Diagnosis. Females of S. mapia sp. n. resemble those of S. muirapinima sp. n. and S. urucu by the epigyne with MS bearing a single anterior epigynal pocket ( Figs 29 View FIGURES 29−33 , 46 View FIGURES 43−47 , 79 View FIGURES 77−80 ). They are distinguished from those of S. muirapinima sp. n. by the pocket as wide as long (much wider than long in the latter species) and from S. urucu by the median septum roughly rectangular, with sinuous lateral margins (roughly trapezoid in the latter species) ( Fig. 29 View FIGURES 29−33 ). Males are unknown.

Description. Female (holotype): Prosoma pale brownish yellow with irregular brown marks between thoracic striae and at the base of cephalic region; fovea and thoracic striae brown; eye borders black. Chelicerae, legs and palps yellowish orange with faint pale brown marks at the base of spines and setae. Labium brown, distally orange brown. Endites yellowish cream colored, Sternum yellowish cream colored with brown margins. Opisthosoma dorsally brownish yellow with gray marks around pale heart mark and one pair of brown muscle impressions; ventrally brownish cream colored with two curved lines of muscle impressions. Spinnerets pale yellow ( Figs 34−35 View FIGURES 34−37 ). Total length 6.8. Prosoma: 3.1 long, 3.2 wide. Opisthosoma: 3.6 long, 2.7 wide. Eyes: diameters: 0.19, 0.24, 0.17, 0.25; interdistances: 0.15, 0.05, 0.32, 0.30, 0.29, 0.30. Legs (2143): I: 16.6 (4.7, 1.5, 4.9, 4.0, 1.5); II: 18.6 (5.3, 1.7, 5.6, 4.5, 1.5); III: 13.2 (4.0, 1.0, 3.6, 3.3, 1.3); IV: 14.5 (4.3, 1.1, 3.8, 3.8, 1.5). Epigyne: epigynal field longer than wide; anterior epigynal pocket wider than long, opening posteriorly; MS longer than wide ( Figs 29 View FIGURES 29−33 , 38 View FIGURES 38−42 ). Vulva: internal ducts sinuous, running posteriad; SP u-shaped; FD short, anteriad ( Figs 30 View FIGURES 29−33 , 39 View FIGURES 38−42 ).
