Figs 1–2 , 24 , 40

Cyclosternum versicolor Simon, 1897: 3 . Holotype female, MNHN 18359, from Paraguay, MNHN, examined; Mello­Leitão 1923: 153; Bonnet 1956: 1327.

Hapalopus versicolor: Roewer 1942: 231 .

Cyriocosmus versicolor: Schiapelli & Gerschman 1973: 69 , figs 5–8, 19–21; Pérez­Miles 1998: 101; Schmidt 1999: 5, figs 4–6.

Additional material examined: 1 male, MACN­Ar 6525, from Salta, Argentina, M. E. Galiano, 26 October 1967, det. Schiapelli & G. de Pikelin.

Diagnosis: The female can be distinguished from all species, except C. sellatus , by the absence of an abdominal pattern ( Fig. 40 ). From C. sellatus it can be distinguished by having a dark cephalic area. The male differs from all other species, except C. bertae and C. sellatus , by the absence of a striped dorsal abdominal pattern. From C. sellatus it can be distinguished by its short paraembolic apophysis ( Figs 1, 2 ) and from C. bertae by the absence of a retrolateral field of spiniform hairs and the presence of a retrolateral process, both on the palpal tibia.

Distribution: Paraguay and Argentina ( Fig. 56 ).
