The genus was recently reviewed by The material examined is deposited in the Lise et al. (2009), who described four new spe- arachnological collections of the following: Museo cies: C. meridionalis, from Brazil and Argentina; Argentino de Ciencias Naturales, Buenos Aires C. taim, from Brazil, Argentina and Uruguay, (MACN-Ar, C. L. Scioscia), Muséum National and C. brescoviti and C. tocantins, from Brazil. Moreover, Dankittipakul et al. (2012) transferred d´Histoire Naturelle, Paris (MNHN, C. Rollard), Storena lentiginosa Simon to Cybaeodamus. and Museo de Entomología “Klaus Raven Büller” Males of this genus are recognized by the of the Universidad Nacional Agraria La Molina, presence of two tegular apophyses on the male Lima (MEKRB, M.

Photographs of the palpus (distal and lateral) of which the distal one preserved specimens were taken with a digital is large and complex; females have a large epigy- camera Leica DFC 290 mounted on a stereomi- num with a strongly sclerotized area at the sides; croscope Leica M165 C, and the focal planes were the chelicerae of both sexes are densely setose. composed with Helicon Focus 4.62 Pro (www. The only species known from Chile is heliconsoft.com). We report GPS coordinates Cybaeodamus lycosoides (Nicolet, 1849), known of the localities when available; otherwise, we only by the female, and without specific locality provide approximate coordinates (denoted with data. In recent times, this species was collected “ca.”) calculated with Google Earth (http://earth. during arthropod inventories made in different areas in the coastal desert from North-Central google.com) from label data.
