Adcatomus ciudadus Karsch, 1880: 387 View in CoL , pl. 12, fig. 13 (Male holotype from Lima, Peru, V. Winthem leg., deposited in ZMB 1863, not examined). Simon, 1897: 89; Petrunkevitch, 1911: 135; 1928: 171; Roewer, 1954: 476; Bonnet, 1955: 158; Jäger, 2000: 238, figs. 1–8, 18; Platnick, 2008.

Material examined. VENEZUELA. 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 View FIGURES 3 – 10 ).

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 View FIGURES 1 – 2 ). 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 View FIGURES 1 – 2 ). 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 View FIGURES 1 – 2 ). Ventral femora and tibiae I––IV densely covered with orange hairs. Total length 18.3. Prosoma: 7.8 long, 7.5 wide. Eye diameters and interdistances: AME 0.46, ALE 0.46, PME 0.32, PLE 0.32, AME–AME 0.30, AME–ALE 0.14, PME– PME 0.60, PME–PLE 0.66, AME–PME 0.44, ALE–PLE 0.30. 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. Leg spination follows the generic pattern. Opisthosoma: 10.4 long, 6.5 wide.

Distribution. Known from northern South America: Peru and Venezuela.
