Geographically, 70% of this group was found to the east of 100o W latitude and was concentrated at the eastern extreme of the neovolcanic axis in the states of Puebla, Hidalgo, and Veracruz, and extending down into Oaxaca (Fig.
Both molecular clock calibrations (based on Nei's D) and geological-age estimates of the Mexican Neovolcanic Axis are consistent with an initial divergence of no more than 10 million years for the Mexican taxa, and many species are apparently much more recently derived (Shaffer 1984a).
