Aragua: 1#m 1#f, Colonia Tovar (10°25'N, 67°18'W, 2.100 m), Dec. 2002, A. Pérez González & A. Giupponi (MHNLS II- 489). Diagnosis. For males see generic diagnosis. Females are distinguished from those of A. flavovittatus by the absence of intermarginal denticles on the chelicerae furrow and by the median septum with a narrower posterior region and a larger atrium in the female epigynum (Fig. 9). Description. Male (MHNLS II-489): Prosoma reddish-brown, brown along fovea and thoracic striae. Clypeus dark brown. Chelicerae very dark brown with large anterior reddish-brown mark (Fig. 1). Legs reddish-brown, except metatarsi and tarsi dark brown. Sternum brown. Labium and endites brown, distally dark brown. Opisthosoma dorsally brownish gray with brown irregular pattern (Fig. 1). Ventrally with large median longitudinal brown band. Total length 15.0. Prosoma: 6.5 long, 6.3 wide. Eye diameters and interdistances: AME 0.48, ALE 0.40, PME 0.36, PLE 0.40, AME–AME 0.26, AME–ALE 0.06, PME–PME 0.50, PME–PLE 0.50, AME–PME 0.40 ALE–PLE 0.30. Chelicerae with no intermarginal denticles. Leg measurements: I: femur 13.0; patella 3.8; tibia 12.6; metatarsus 12.1; tarsus 3.3; total 44.8; II: 12.6; 3.9; 12.5; 12.0; 3.3; 44.3; III: 10.0; 3.2; 8.8; 8.0; 2.3; 32.3; IV: 11.0; 3.1; 8.9; 9.0; 2.5; 34.5. Leg spination follows the generic pattern. Opisthosoma: 8.5 long, 5.4 wide. Female (MHNLS II-489): Coloration pattern as in male, slightly lighter (Fig. 2). Ventral femora and tibiae I––IV densely covered with orange hairs. Total length 18.3. Prosoma: 7.8 long, 7.5 wide.

Leg measurements: I: femur 10.0; patella 3.9; tibia 9.0; metatarsus 8.7; tarsus 2.3; total 33.9; II: 10.1; 3.9; 9.2; 8.5; 2.2; 33.9; III: 8.3; 3.1; 6.8; 6.2; 2.0; 26.4; IV: 9.0; 3.1; 6.2; 6.9; 2.2; 27.4.
