Redescription. Male. Pronotum and legs brown; face, lower margin of lateral lobes of pronotum, thoracic and abdominal sternites yellow-greenish; post-ocular stripe, most of the dorsal part of abdominal tergites and hind wings black ( Fig. 8AView FIGURE 8); tegmina black with a broad, light colored stripe covering at least half the ventral edge, and a large ellipsoidal subapical spot ( Fig. 8CView FIGURE 8). Head. Stout, eyes moderately globose ( Fig. 8BView FIGURE 8), fastigium of the vertex prolonging in the middle of the eyes in side view and truncated at the tip, much below the dorsal surface of the eyes ( Fig. 8CView FIGURE 8), frontal costa short and very narrow scutellum, directed back from the fastigium; lateral carinae arising at the level of the fastigium, flared between paired ocelli and antennal grooves ( Fig. 8bView FIGURE 8). Pronotum, extending noticeably into the abdomen, being twice as long as the thorax and abdomen put together ( Figs. 8A,DView FIGURE 8); anterior spine slender, short and decurved forward ( Fig. 8CView FIGURE 8); mid line of the pronotal disc moderately elevated in the middle of the pronotum and moderately undulated at the level of the mesothorax ( Fig. 8DView FIGURE 8); lateral lobes of the pronotum wider than long, lateral shoulder carina notoriously long and rounded, with the lower margin converging in a triangular, non-acute angle; hind stripe of the lateral lobes of the pronotum present in the first basal two-thirds, not reaching thr lateral shoulder carina ( Fig. 8CView FIGURE 8). Tegmina lance-shaped and elongated, hind wings overcoming the tip of the pronotum noticeably. Legs slender, fore femora without an apical spine, midfemora with a small, internal, dorso-apical spine, hind femur with a poorly developed pregenicular spine, this sometimes absent. Abdomen. Subgenital plate short and narrow, non-cupuliform, narrowing distally ( Fig. 8EView FIGURE 8), without a mid-longitudinal carina, penultimate sternite broadly and deeply notched on mid-apical edge ( Fig. 8FView FIGURE 8), stout cerci (much stouter than other species of the genus) and cylindrical ( Fig. 8FView FIGURE 8), epiproct short and as long as wide.

Female. Similar in color and build to the male, with no variation worth noting related to sex except of course for the terminalia ( Figs. 9View FIGURE 9 A–D). Subgenital plate wider than long, with a very low, arcuate, median lobe, with no lateral prolongations ( Fig. 9EView FIGURE 9); ovipositor very short and stout compared with other species of the genus; cerci quite stout and cylindrical ( Fig. 9FView FIGURE 9).

Variations. The apical spine of the mid femora varies from obsolete to moderately well developed.

Measurements: CFP: 14,9-13,7; VE: 1,1-0,8; HE: 1-0,9; VW: 1,4-0,8; PL: 13,7-11,9; PLB: 2,4-1,9; FF: 3,2- 2,7; FL: 2,9-2,4; MFL: 2,9-2,8; MTL: 2,-–2,2; HL: 7,3-5,6; HW: 1,9-1,5; HL: 5,6-4,6.

Distribution. Amazonia of Colombia, Brazil and Peru.

Comments. Data from ANSP and AMNH are from Grant, 1962. The validity of the species is reinstated after it was synonymized by Cadena-Castañeda & Cardona (2015) under S. ferruginea  . Lectotype and paralectotypes are proposed according to the outline from Article 74 (ICZN: International Code of Zoological Nomenclature).
