Abstract
-
The first phylogenetic analysis and taxonomic revision of the North American vaejovid scorpion subfamily Syntropinae Kraepelin, 1905 are presented. The phylogeny is based on a simultaneous analysis of DNA (5 loci) and morphological characters (continuous and discrete). The current classification of the subfamily (Soleglad and Fet, 2008) was tested for monophyly and the relative positions of insertae sedis taxa putatively related to the subfamily were investigated. Nodal stability and nodal support for the resultant topologies were high; although the molecules and morphology had dissimilar phylogenetic signals, simultaneous analyses enhanced the overall signal and thus generated the hypothesis with the most explanatory power. Syntropinae and Stahnkeini Soleglad and Fet, 2008 were recovered as monophyletic. The Syntropinae comprised six monophyletic groups that contradicted the current classification. The following taxonomic emendations are proposed. The tribe Paravaejovini Soleglad and Fet, 2008 and subtribe Thorellina Soleglad and Fet, 2008 are synonymized with Syntropinae; the Syntropinae is redefined with eleven genera. Six new genera are described, Balsateres n. gen., Chihuahuanus, n. gen., Konetontli, n. gen., Maaykuyak, n. gen., Mesomexovis, n. gen., and Vizcaino, n. gen. Hoffmannius, syn. n. is synonymized with Paravaejovis and 15 species are transferred to other genera. Five subspecies are elevated to species, two restored from synonymy and 26 new species described. Possible scenarios of the evolution and biogeography of the genera and species are presented, from a historical and ecological perspective.
