| Uncus short, triangular, with a blunt tip. Valvae small, oval-shaped, distally rounded, outer surface with long extrusible, hirsute, tube-like coremata; inner sclerotized process short, slender, smooth, and curved. Vesica distally with two straight, parallel cornuti of slightly unequal size, fused at their base. |
| Distribution Central Africa; southern Zaire; only known from Lubumbashi. |
| Comments The female of this species is similar to A. androfusca, but considerably smaller. In the male genitalia, A. lineolata is also close to A. androfusca and agrees well with other African Amerila. Therefore, we see no reason to place this species in a separate genus as proposed in the original description by Kiriakoff (1954). |
