description: <i>Cybaeodamus lycosoides</i> (Nicolet, 1849) (Figures 1–4) <i>Drassus lycosoides</i> Nicolet, 1849: 453 (female). <i>Storena lycosoides</i>: Simon, 1889: 218. <i>Cybaeodamus lycosoides</i>: Jocqué, 1991: 50; Lise, Ott &amp; Rodrigues, 2009: 266, f. 48–49. <b>Type Material.</b> Female holotype from “ Chili ”, without data (see Lise et al. 2009: 266; MNHN 9954). Examined. <b>Material examined.</b> CHILE: IV Región, Coquimbo, Punta de Choros, Sitio 2, 26º70’46” S, 67º59’074” W: 2 &amp;female;, (MACN-Ar 17620), 03.VI.2005, P. Augustocoll.; 1 &amp;male;, (MACN-Ar 17621), 4.VI.2005, L. Espinoza coll. PERU: Dept. Lima, Prov. Lima, dist. La Molina, Univ. Nac. Agraria La Molina (pitfalls in cotton fields), S 12º06’, W 76º57’, 243 m: 1 &amp;male;, (MEKRB, UA-524/2005), 10.VIII.2005, M. Deza coll.; 2 &amp;male;, (MEKRB, UA-273/2010), II. 2010, M. Deza &amp; J. Andía coll.; Depto. Ica, Prov. Pisco, Sector Figueroa, 10.VI.2008, J. Andía coll. 1 &amp;male; (asparagus fields, MEKRB). <b>Diagnosis.</b> Males of <i>C. lycosoides</i> are very similar to the those of <i>C. ornatus</i> 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); the distal branch is much longer than the proximal branch in <i>C. ornatus</i>), and also by the retrolateral tibial apophysis, that bears a tiny dorsal tooth (Fig. 4A). For the female see Lise <i>et al</i>., 2009 (figs. 48, 49, 52, 53), and Jocqué, 1991 (fig. 87). <b>Male description</b> (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); general color reddish brown with dark margins; glabrous, with only afew white setae on cephalic region. Chelicerae reddish brown, densely setose (Fig. 2D). Endites subtriangular, reddish brown, with whitish tip (Fig. 2B). Labium reddish brown. Sternum reddish brown with lighter central area, setae most abundant at margins (Fig. 2B). Anterior and posterior eye rows slightly procurved (Fig. 2D). 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). 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 I-II d1-1 pl1 III-IV d8; patellae III-IV rl1; tibiae I v8 pl2-2-1 II v8 III v2-2-2 pl2-2-1 rl0-1-1 d1-1-1 IV v2-2-2 pl1-1-1-1 rl3 d1-1-1; metatarsi Iv2-1- 2-2 II v2-2-1-2 III 18 dispersed, IV 25 dispersed. Variation: femora IV d7 (in the same specimen). <b>Variation.</b> Males (5). Total length: 9.98 – 12.64; carapace: 5.00 – 6.13 (specimens from Peru are larger). <b>Natural history.</b> <i>Cybaeodamus lycosoides</i> 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 <i>et al</i>., 2013). <b>Distribution.</b> Pacific coast of Chile (Coquimbo and Atacama) and Peru (Lima and Ica).
