| 1. | Midvein and marginal veins are visible.
|
| 2. | Veins on the leaves are distinct and the marginal vein is notably distant from the leaf edge.
|
| 3. | The hindwing upperside is brown, with a black marginal dot at the tornus and marginal vein dots.
|
| 4. | The flexible leaves are flat and linear and concave or trigonous long and wide with prominent marginal veins.

| 5. | It has pinnately incised prickly leaves and prickly wings along the stems, both with a white marginal vein.
|
| 6. | Net veins are not seen, although there is an indistinct intra-marginal vein around the edge of the leaf.
|
| 7. | The leading edge of each wing has a node where other veins join the marginal vein, and the wing is able to flex at this point.
|
| 8. | The costa ( C ) is the leading marginal vein on most insects, although a small vein, the precosta, is sometimes found above the costa.
|
| 9. | The "'medial marginal vein "'is a continuation of the Dorsal venous arch of the foot and is the origin of the long saphenous vein.
|
| 10. | The "'lateral marginal vein "'is a continuation of the Dorsal venous arch of the foot and is the origin of the short saphenous vein.
