Diagnosis. Females of A. trinotatus are characterized by the asymetrical seminal receptacles, bilobed or trilobed; receptacles subquadrate, parallel to each other, without lateral swelling ( Fig. 220 A View FIGURE 220 ); crown of thorns on the patella III interrupted in prolateral and retrolateral faces ( Fig. 219 A View FIGURE 219 ).

FEMALE (holotype): Total length 15.86; Carapace, long 6.76; wide 8.22. Parallel lateral margins of carapace. Anterior eye row procurved, posterior row recurved.Many long bristles and short bristles between AME-clypeus, forming two slightly procurved rows in interdistances PME–PME and PLE–PLE. Short bristles between AMEclypeus and between lateral eyes-edge of carapace. Long bristles in chilum ( Fig. 218 B View FIGURE 218 ). Sternum with eight sigilla strongly fused medially ( Fig. 218 C View FIGURE 218 ). Rastellum protuberant, digitiform, hirsute, with short spines along retrolateral edge of rastellum and dorsally covered by small short spines ( Fig. 218 View FIGURE 218 E–F). Chelicerae with denticles along prolateral row of teeth. Denticles in the middle of prolateral and retrolateral rows of teeth ( Fig.218 D View FIGURE 218 ).Patella and tibia III with distal developed crowns of thorns ( Fig. 219 View FIGURE 219 A–B). Tibia III with recurved distal crown of spines and strong spines along retrolateral surface of article ( Fig. 219 B View FIGURE 219 ).
