Redescription. Female. Pronotum, tegmina, wings and thoracic sternites brownish black, tegmina with a subapical ovoid, yellowish spot; dorsal midline brownish white as are the legs and head. Postocular strip usually lacking (in a few specimens there was a faint hint of a line); lower half of the lateral lobes of the pronotum and the greater part of the abdomen whitish ( Fig. 18AView FIGURE 18). Head, stout and moderately elongated, eyes globose and moderately long ( Fig. 18BView FIGURE 18); fastigium of vertex rounded and poorly projected, frontal costa lowly, but evenly arcuate in lateral view, reaching near the middle of the face; narrow scutellum; dorsal carina arising at about the level of fastigium, short usually sloping obliquely ventrad as part of the outline of the whole structure ( Fig. 18CView FIGURE 18). Pronotum, flat, extending a little longer than hind femora ( Fig. 18AView FIGURE 18), anterior spine of pronotum stout, curving gradually towards the front, covering the vertex in part. ( Fig. 18CView FIGURE 18); median carina continuous and slightly raised from anterior spine to pronotal tip, this carinae pigmented by a brown whitish line ( Fig. 18DView FIGURE 18); lateral lobes of the pronotum wider than long, lateral shoulder carina rounded and poorly projected; posterior margin of the lateral lobe sharped ( Fig. 18CView FIGURE 18). Tegmina with a prominent subapical ovoid spot, this usually light yellow or white, tegmina ovoid and short compared to other species of the genus, covering the base of the first abdominal tergite ( Fig. 18CView FIGURE 18). Legs short and slender, fore femora with a weak sulcation above for its entire length, mid femora with a well-developed to strongly developed internal, dorso-apical spine; hind femora with a pre-genicular spine developed. Abdomen. Subgenital plate a little longer than wide ( Fig. 18FView FIGURE 18), with a roundish mid-indentation with no additional protrusions; ovipositor 1.5 times as long as subgenital plate ( Fig. 18EView FIGURE 18), epiproct long and triangular shaped; cerci conical and tapering gradually to the tip ( Fig. 18GView FIGURE 18).

Male (novum). Similar to the female in color and structure of body but differs in the ambisexual characters ( Figs. 19View FIGURE 19 A–D): subgenital plate moderately short and inflated ( Figs. 19View FIGURE 19 E–F), epiproct subtriangular with a small distal protrusion ( Fig. 19EView FIGURE 19); cerci cylindrical and tapering progressively towards the tip. ( Fig. 19GView FIGURE 19); penultimate abdominal sternite with a weak medial protrusion ( Fig. 19FView FIGURE 19).

Variation. Post-ocular stripe usually lacking, though it can occur, weakly and indistinctly, in some specimens; mid-longitudinal stripe of light brown, tan or cream color; tegmina rarely with a basal, light yellowish spot.

Measurements: CFP: 13,4-13,1; VE: 1,1-0,8; HE: 1-0,9; VW: 1,4-0,8; PL: 12,6-12,4; PLB: 3-2,6; FF: 3,7-3,3; FL: 2,7-2,6; MFL: 3,9-3,6; MTL: 3,1-2,9; HL: 8-7,4; HW: 2,5-2,1; HL: 6,6-6.

Distribution. Widely distributed in the Amazon and the Andean piedmont of Colombia, Ecuador, Peru, Brazil and Bolivia.

Comments. This species was synonymized under S. lineata  by Grant, 1902; and under S. laeta  by Cadena- Castañeda & Cardona, 2015; we hereby revalidate its status and a re-description is provided for its accurate determination. Because S. ferruginea  has a distinct dorsal line, it was mistaken in the past with S. lineata  (Westerdujin & Cadena-Castañeda, 2014; Huamán et al, 2014), from which it differs by color pattern (in this species the usual color is dark brown) the post-ocular stripe is usually lacking, and the ovipositor differs (very short in S. ferruginea  and normal-sized in S. lineata  ). Also, tegmina spot is lacking in S. lineata  but conspicuous in S. ferruginea  .
