Key to species identification based on male genitalia

1. Cucullus with brush of hairs on ventral margin (Fig. 29)............................................. A. strigifera

- Cucullus without brush of hairs on ventral margin (Figs 23–28, 30–32).......................................... 2

2. Phallus with lateral process (Figs 23, 24, 26, 27, 30)......................................................... 3

- Phallus without lateral process, with twisted trunk inside (Figs 25, 28, 31)........................................ 6

3. Cucullus parallel-sided to 3/4 of its length, uncus strongly constricted at base, lateral process very short (Fig. 23, 24)......................................................................................... A. angustella sp. nov.

- Cucullus broadened to 2/3–3/4 of its length, uncus not constricted at base, lateral process larger (Figs 26, 27, 30)......... 4

4. Lateral process large, uncus longer than tegumen, saccus U-shaped (Fig. 26)......................... A. fuscomaculata

- Lateral process short, uncus as long as tegumen, saccus V-shaped (Figs 27, 30).................................... 5

5. Uncus with posteromedial emargination, valvella rounded (Fig. 27)............................ A. lacistoides sp. nov.

- Uncus without posteromedial emargination, valvella elongate (Fig. 30).................................. A. tauropis

6. Phallus longer than cucullus (Fig. 25)........................................................... A. centrotypa

- Phallus as long as or shorter than cucullus (Figs 28, 31)...................................................... 7

7. Cucullus parallel-sided to 2/3 of its length (Janse1958: pl. 6; 1960: pl. 49d)................................ A. hirsuta

- Cucullus gradually widened apically (Figs 28, 31)........................................................... 8

8. Gnathos with subapical hump on ventral side, cucullus extending to 1/2 length of uncus (Fig. 28).. A. ochrocapitella sp. nov.

- Gnathos without subapical hump on ventral side, cucullus extending to 2/3–3/4 length of uncus (Fig. 31)................................................................................................. A. unipunctella sp. nov.
