Key to Scaria  species

1. Lateral carinae of frontal costa subparallel or divergent, but never flared. Tegmina with spots or not, but never with a ventral strip. Male terminalia with subgenital plate usually mid-sized and globose, and with slender, non-conical cerci, ovipositor valves elongate, dagger like............................................................................. 2

Tegmina with a broad, light colored stripe covering at least half the ventral edge, and a large ellipsoidal subapical spot ( Figs. 8CView FIGURE 8, 9CView FIGURE 9). Male terminalia with short, thin subgenital plate, cerci stout and conical ( Figs. 8View FIGURE 8 E–G); ovipositor valves short and broad ( Figs. 9E,FView FIGURE 9) (Laeta Group) .......................................................................................... S. laeta  stat. ressurr.

2. Face greenish-yellow or whitish and post-ocular stripe present (excluding S. ferruginea  ), margin of prozona moderately curved and raised towards the anterior spine...................................................................... 4

- Face brownish, lacking a post-ocular stripe ( Figs. 10CView FIGURE 10, 12CView FIGURE 12), margin of prozona strongly curved and raised towards the anterior spine ( Figs. 11AView FIGURE 11, 12AView FIGURE 12) (Producta Group) ................................................................. 3

3. Pronotum dark brown with a dorsal, reddish brown spot ( Fig. 1View FIGURE 1). Hind femora without lobes on dorsal edge. Tegmina spotless, subgenital plate of males curving upwards in a 90 90° angle ( Fig. 10EView FIGURE 10)................................... S. maculata 

- Pronotum brown with a green lime stripe in the lower half of the lateral lobes of pronotum and well into the dorsal median line of the pronotal disc ( Fig. 11A,DView FIGURE 11, 12A,DView FIGURE 12). Hind femora with two or three low lobes along dorsal edge ( Fig. 2IView FIGURE 2). Tegmina with a basal spot and subapical spot ( Figs. 11CView FIGURE 11, 12CView FIGURE 12), Subgenital plate in males not curving as noticeably ( Figs. 12E,FView FIGURE 12)...................................................................................................... S. producta 

4. Face whitish (only S. ferruginea  has a brownish face), mid femora length 3–4 times longer than wide, most ventral border of the eyes on a line with or below most of the dorsal height of the exposed area of the tegmina; male epiproct with a narrow distal prolongation; pronotum mostly black, in most cases also with a whitish line align the midline of the pronotal disc, line that can either be simple or expand to cover all the pronotal disc (in S. fasciata  some specimens display a couple of whitish lines, one to each side of the lateral margin of the pronotal disc) (Lineata Group).......................................... 5

- Face yellowish-green (rarely brown-greenish), mid femora six times longer than wide, most ventral border of the eyes higher than the most dorsal exposed area of the tegmina; male epiproct with no distal protrusion, pronotal coloration lime green or green-bluish (Hamata Group) .......................................................................... 8

5. Dorsal midline present, covering only the midline ( Fig. 15BView FIGURE 15) or expanding to cover the whole of the pronotal disc ( Fig. 17BView FIGURE 17) ................................................................................................... 6

- Dorsal midline lacking, ( Fig. 15BView FIGURE 15) a white line on each side on the lateral border of the pronotal disc occurring in some specimens ( Fig. 13BView FIGURE 13)................................................................................ S. fasciata 

6. Cephalic capsule whitish, always with a post-ocular stripe, ovipositor 2.5 times as long as the as subgenital plate......... 7

- Cephalic capsule brown, post-ocular stripe usually lacking ( Figs. 18CView FIGURE 18, 19CView FIGURE 19), but when it occurs, it is very slight; ovipositor 1.5 times as long as subgenital plate ( Fig. 18GView FIGURE 18)........................................................ S. ferruginea 

7. Pronotal disc with a mid-dorsal line, spotless tegmina ( Figs. 15View FIGURE 15, 16View FIGURE 16)....................................... S. lineata 

- Pronotal disc whitish overall, tegmina with an ovoid subapical spot ( Fig. 17View FIGURE 17)..................... S. verutum  comb. nov.

8. Stripe of the upper half of the lateral margin of the pronotum black and only covering the upper margin of the lateral lobe of the pronotum; male epiproct with a triangular tip, penultimate male sternite rounded and poorly pronounced................ 9

- Stripe of the upper half of the lateral margin of the pronotum black and slight, being only a line that separates the lower and upper margins of the lateral lobes of the pronotum; male epiproct with a rounded tip, penultimate male sternite with a triangular projection.......................................................................................... 10

9. Male and female coloration much alike, variable but never olive-green with irregular, diffuse, dark brownish stripes ( Figs. 20AView FIGURE 20, 21AView FIGURE 21). Male cerci with a similar thickness in all their length and with an obliquely truncated tip ( Fig. 20GView FIGURE 20). Ovipositor slender, 2.5 times as long as subgenital plate ( Fig. 20FView FIGURE 20)....................................................... S. hamata
