A new species of the Vaejovis eusthenura group in Oaxaca, Mexico (Scorpiones: Vaejovidae)

摘要

Vaejovis oaxaca, a new species of the Vaejovis eusthenura group is described from the Mexican state of Oaxaca. It is found in lowlands ranging from the Mitla area in central Oaxaca southeast into the Isthmus of Tehuantepec and the eastern edge of Chiapas. The genus Vaejovis C. L. Koch, 1836 is the most diverse element of the North American scorpiofauna (Sissom 2000), with over 70 described species. For many years, the genus was subdivided into a number of species groups and a small number of unassigned species. Recently, the species groups were given generic status by Soleglad & Fet (2008), but these authors provided no cladistic tests of monophyly for the proposed new genera, and their previous efforts at cladistic analysis were demonstrated to begreatly flawed (Prendini & Wheeler 2005). Consequently, we prefer to retain the genus Vaejovis in its previous state, most recently summarized by Sissom (2000) and Prendini & Wheeler (2005), pending the production of a valid cladistic analysis.
