| Abstract: | "A cladistic analysis based on parsimony is undertaken to test hypotheses concerning the monophyly of the ctenid spiders and the relationships among their various clades. The data matrix comprised a total of 98 species representing 16 families scored for 146 characters, with all but six taken from various morphological systems; the remaining are behavioral attributes. Ctenidae is shown to be polyphyletic as currently delimited, but the most severely questioned taxa (i.e., Acanthoctenus, Cupiennius, and Ancylometes) are indeed members of this family. The so-called ctenid eye pattern is shown to be a synapomorphy uniting a more restricted set of taxa. This clade is recognized as Ctenidae sensu stricto and it comprises at least five major lineages: Acantheinae, Acanthocteninae, Calocteninae, Cteninae, and Viridasiinae. The latter taxa are hypothesized to be the sister group of all other ctenids. In turn, a clade formed by Miturgidae s.s. and Zoridae s.s. is proposed as the sister group of... |
