Diagnosis. Males of C. lycosoides are very similar to the those of C. ornatus by general morphology of the palp, the cusps on coxae IV and the ventral patch of thickened setae on the abdomen, but differ by the shape of the distal tegular apophysis, with the two branches similar in size ( Figs. 3A, C View Fig ); the distal branch is much longer than the proximal branch in C. ornatus ), and also by the retrolateral tibial apophysis, that bears a tiny dorsal tooth ( Fig. 4A View Fig ). For the female see Lise et al., 2009 (figs. 48, 49, 52, 53), and Jocqué, 1991 (fig. 87).

Male description (MACN-Ar 17621). Total length 9.98. Carapace 5.20 long, 3.40 wide, 1.67 high. Sternum 2.40 long, 1.80 wide. Carapace broadly oval, narrower at the cephalic region ( Fig. 2A View Fig ); general color reddish brown with dark margins; glabrous, with only afew white setae on cephalic region. Chelicerae reddish brown, densely setose ( Fig. 2D View Fig ). Endites subtriangular, reddish brown, with whitish tip ( Fig. 2B View Fig ). Labium reddish brown. Sternum reddish brown with lighter central area, setae most abundant at margins ( Fig. 2B View Fig ). Anterior and posterior eye rows slightly procurved ( Fig. 2D View Fig ). Abdomen 5.07 long, 3.07 wide, 2.93 high. Color: background pale yellow with small black dots at sides and venter; the dots converge along the cardiac area in a chevron-like pattern with a more definite dark patch on the anterior part ( Fig. 1A View Fig ). Legs: coxae, trochanters and femora reddish-brown, with faint longitudinal lighter stripes; distal articles orangish brown. Leg formula 4123. Measurements I/II/III/IV: femur 3.47/3.33/3.00/3.87; patella 1.40/1.40/1.33/1.53; tibia 2.73/2.07/1.87/2.80; metatarsus 2.60/2.47/2.47/3.47; tarsus 1.87/1.53/1.60/1.80. Total 12.07/10.80/10.27/13.47. Spination: femora

Variation. Males (5). Total length: 9.98 – 12.64; carapace: 5.00 – 6.13 (specimens from Peru are larger).

Natural history. Cybaeodamus lycosoides inhabits primarily under stones and logs, in arid areas: transitional coastal desert in Chile, and coastal valleys and Loma-vegetation in Peru. In both countries, this species was also found associated with agroecosystems ( Alcayaga et al., 2013).

Distribution. Pacific coast of Chile (Coquimbo and Atacama) and Peru (Lima and Ica).
