- RTA not reaching cymbium, either short or directed sideward (Fig. 9)............................................4
3. Embolus tip with anterior prong thin and much longer than posterior one; insertion of RTA near distal margin of tibia (Polotow & Jocqué 2015: fig. 5A); tibia with two long pro- and retrolateral spines........................... A. immortalis (Arts)
- Embolus tip with short and broad prongs; insertion of RTA somewhat behind anterior margin of tibia (Polotow & Jocqué 2015: fig. 11A); tibia with one long lateral spine........................................... A. hybrida Polotow & Jocqué
4. MA straight; embolus not bifid but with posterior indentation near tip (Fig. 9)....................... A. tanga new species
- MA sinuous; embolus bifid at tip (Polotow & Jocqué 2015: fig. 7A).............................................5
5. Posterior prong of embolus tip thin, curved and clearly longer than anterior prong; RTA small and narrow (Polotow & Jocqué 2015: fig. 7A); venter of the opisthosoma without black area (Polotow & Jocqué 2015: fig. 6B)..... A. erythrochelis (Simon)
- Anterior prong of embolus tip the longest or both prongs of the same size; RTA large and broad (Polotow & Jocqué 2015: figs 3A, 9A); venter of the opisthosoma with dark area (Polotow & Jocqué 2015: figs 2B, 8B)............................6
6. Prongs of embolus tip of the same length; RTA with sharp superior and inferior tips (Polotow & Jocqué 2015: fig. 3A); venter of the opisthosoma with small black area not surpassing the middle, with two spots (Polotow & Jocqué 2015: fig. 2B).................................................................................... A. velox (Blackwall)
- Anterior prong of embolus tip clearly longer than posterior one; RTA with sinuous, serrated distal margin (Polotow & Jocqué 2015: fig. 9A); venter of the opisthosoma with large black area surpassing the middle, with four spots (Polotow & Jocqué 2015: fig. 8B)........................................................... A. quadrimaculata Polotow & Jocqué
7. Lateral projections sharp and strongly converging in an angle of 45° to the longitudinal axis; median sector fairly narrow, smoothly rounded towards narrow base (Polotow & Jocqué 2015: fig. 5D); venter of the opisthosoma entirely black (Polotow & Jocqué 2015: fig. 4D)................................................................. A.immortalis (Arts)

8. Median sector broad (L/W in the middle = 1.8); copulatory ducts ending in a close spire (Polotow & Jocqué 2015: figs 7C–D); venter pale with a few darker spots (Polotow & Jocqué 2015: fig. 6D)............................... A. erythrochelis

9. Median sector with strongly tapered anterior and rectangular posterior parts; copulatory ducts without forward running stretch (Polotow & Jocqué 2015: fig. 3D–E); black area of abdominal venter not extended beyond the middle (Polotow & Jocqué 2015: fig. 2D).................................................................................. A. velox
- Median sector differently shaped; copulatory ducts with distal part running forward before connecting to the spermathecae (Polotow & Jocqué 2015: figs 9D–E); ventral dark area of the opisthosoma venter extended beyond the middle (Polotow & Jocqué 2015: fig. 8D).................................................................................10
10. Median sector narrow (L/W in the middle ± 3.5); copulatory ducts running forward and towards the middle before connection to the spermathecae, which are less than half their diameter apart (Polotow & Jocqué 2015: figs 9D–E); ventral black area of the opisthosoma extended beyond the middle (Polotow & Jocqué 2015: fig. 8D)...... A. quadrimaculata Polotow & Jocqué
- Median sector wider (L/W in the middle ± 2.6); copulatory ducts running forward but not towards the middle before connection to the spermathecae, which are their diameter apart (Figs 10–11); venter of the opisthosoma with black area anterior to the epigastric furrow (Fig. 4)............................................................... A. tanga new species
