Number two is definitely Vaejovis waeringi. The rest appear to be V spinigerus If I had lateral shots of them, i could ID them alot better
In ken's immediate vicinity, there are like what.. 5 different species of Vaejovis, all found in the same area. I used to collect there when I was younger, having family in the same area. I loved visiting there! I would go outside, and find banded geckos, tortoises, desert iguanas, and all sorts of neat critters.
the V waeringi I find interesting, that's a californian species. Perhaps he went collecting in san bernadino county?
