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. 8A ); tegmina black with a broad, light colored stripe covering at least half the ventral edge, and a large ellipsoidal subapical spot ( Fig. 8C ). Head. Stout, eyes moderately globose ( Fig. 8B ), 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. 8C ), 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. 8b ). Pronotum, extending noticeably into the abdomen, being twice as long as the thorax and abdomen put together ( Figs. 8A,D ); anterior spine slender, short and decurved forward ( Fig. 8C ); mid line of the pronotal disc moderately elevated in the middle of the pronotum and moderately undulated at the level of the mesothorax ( Fig. 8D ); 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. 8C ). 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. 8E ), without a mid-longitudinal carina, penultimate sternite broadly and deeply notched on mid-apical edge ( Fig. 8F ), stout cerci (much stouter than other species of the genus) and cylindrical ( Fig. 8F ), 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. 9 A–D). Subgenital plate wider than long, with a very low, arcuate, median lobe, with no lateral prolongations ( Fig. 9E ); ovipositor very short and stout compared with other species of the genus; cerci quite stout and cylindrical ( Fig. 9F ).

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).
