Genus-group names introduced for all extant scorpions in 1758-2006, are listed. The treatment follows the Conspectus of Francke (1985), with considerable additional information accumulated during intensive scorpiological research of 1983-2006. We list, as currently valid, 191 genus-group names, which include 167 genera and 24 non-nominotypic subgenera. The list also includes all available genus-group synonyms as well as unavailable names and detected incorrect spellings.
