This paper gives an updated summary on the diversity of the arder Scorpiones in the Argentinian part of the Western Chaco. A total of 11 species are registered, and they are clasified in three groups, according to their distributional patterns: typical chaco species (Timogenes elegans, Timogenes dorbignyi, Brachistosternus ferrugineus, Bothriurus chacoensis, Tityus confluens), peripherical species (Brachistosternus pentheri, Bothriurus cordubensis n.sp. (hereby named), Urophonius brachycentrus, Tityus trivittatus) and rare species (Vachonia sp., Zabius birabeni). Some comments on the known range of each form are added.
