Taxon Sampling A primary aim of this project is to produce a complete, internally consistent morphological and molecular data matrix for Vaejovidae. This has never been attempted for a major lineage, let alone an entire family, of scorpions. All species will be scored as ingroups for the morphological analysis, and every effort expended to acquire fresh samples of each for DNA isolation. We will attempt to sequence DNA from museum material when no fresh samples are available. Exemplars from the Chactidae, Iuridae, Superstitioniidae, and more distantly related chactoid, scorpionoid and buthoid families and genera, will be included as outgroups to test the various hypotheses that have been proposed to account for the phylogenetic placement of Vaejovidae, as well as the monophyly of the family (Lamoral 1980; Stockwell 1989; Lourenço 2000; Soleglad & Fet 2003, 2004; Coddington et al. 2004).
