Paul Smith and co-workers have recently published a updated review of the scorpion fauna of Paraguay. The country's scorpion fauna seems to consist of at least fifteen species in five genera and three families (Ananteridae, Bothriuridae and Buthidae).
An identification key for the known species of Paraguay is included and the article also comments on some taxonomic problems and biogeography.
Abstract:
We review and map the current distribution of the Paraguayan scorpion fauna using a hierarchical system of reliability, differentiating specimens examined, specimens not examined and photographic records. One new species (Bothriurus sp.), two new national records (Brachistosternus simoneae and Ananteris mariaterezae), and nineteen new departmental distribution records are reported. The national fauna is concluded to be composed of at least fifteen species in five genera and three families, with one other species considered to be of hypothetical occurrence and a further two of probable occurrence. An illustrated key suitable for identifying Paraguayan material is included, and comments regarding taxonomy and systematic problems that remain to be resolved, together with proven and potential medical significance, are provided.
