Key to the species of the simothraulopsis 

Male imagos

1. Penis lobes with lanceolate projection ( Figs 10View FIGURE 10 D, 30D, 45D); penis lobes, ventral region with a well-marked sclerotized region ( Figs 9View FIGURE 9 D, 29D, 44D)...................................................................................2

- Penis lobes with spine-like projection ( Figs 5View FIGURE 5 D, 15D, 40D); penis lobes, ventral region without a well-marked sclerotized region ( Figs 4View FIGURE 4 D, 14D, 39D)............................................................................. 4

2. Body, general coloration orangish; abdominal terga without whitish bands on basal region, tergum IX almost completely black contrasting with the coloration of the other abdominal terga ( Figs 44View FIGURE 44 A –B)............. Simothraulopsis inaequalis  sp. nov.

- Body, general coloration varying from dark brown to blackish; abdominal terga with whitish bands on basal region, tergum IX without a contrasting color pattern ( Figs 9View FIGURE 9 A –B, 29A –B).......................................................3

3. Fore femur, basal 2/3 orangish brown and apical 1/3 whitish; abdominal tergum X whitish ( Figs 9View FIGURE 9 A, B); penis lobes fused on basal ¼, inner margin without a lobular area near fusion of lobes ( Fig. 10View FIGURE 10 D)..................... Simothraulopsis plesius 

- Fore femur completely dark brown; abdominal tergum X brown ( Figs 29View FIGURE 29 A, B); penis lobes fused on basal half, inner margins with a lobular area near fusion of lobes ( Fig. 30View FIGURE 30 D).............................. Simothraulopsis caliginosus  sp. nov.

4. Penis lobes fused on basal 2/3, inner margins parallel or subparallel ( Figs 25View FIGURE 25 D, 35E)................................5

- Penis lobes not fused on basal 2/3, inner margins divergent ( Figs 5View FIGURE 5 E, 15D)........................................ 6

5. Penes, dorsal region with a sclerotized thin plate; penis lobes, inner margin very close, almost touching ( Fig. 25View FIGURE 25 D); abdominal segments II –VI with translucent white basal bands ( Figs 24View FIGURE 24 A, B)............................... Simothraulopsis janae 

- Penes, dorsal region without a sclerotized thin plate; penis lobes, inner margin not very close ( Fig. 35View FIGURE 35 D); only abdominal segments II –IV with translucent white basal bands ( Figs 34View FIGURE 34 A, B)..................... Simothraulopsis dominguezi  sp. nov.

6. Penis projections either long (approximately as long as total length of penis lobes) or of median size (approximately half of the total length of penis lobes) and anteriorly directed ( Figs 5View FIGURE 5 E, 15E)................................................ 7

- Penis projections short (less than the half of total length of penis lobes) and directed to the midline of the body ( Figs 20View FIGURE 20 D, 40D).................................................................................................... 8

7. Forceps, basal region of segment I with a small concavity; penis lobes fused on basal 1/2 ( Figs 15View FIGURE 15 D, E); hind wing, lower portion completely brownish black ( Fig. 15View FIGURE 15 C)................................................ Simothraulopsis sabalo
