Hi Kristian,
Mid-april to Mid-may is the best moment for most reptiles in southern Spain. Like you are telling, when the ground is too hot, Blanus dissapear in the deepest parts of the holes, so the best moment, when you flip stones and it´s very easy to find many Blanus it´s maybe middle april. Later, probably when you flip large flat stones, you will find Macroprotodon (in the same stones where Blanus was some weeks ago). Both Blanus are VERY common. In loose soil areas, it´s very easy to find them
About chamaleons, there are many articles with villages typical of them. You only need to search a bit in Google...
If you find a latastei in Andalussia, please share the photo in the forum. In the biggest part of Andalussia, latastei are very rare (except mountain and some few coastal places). If you need more info, I highly recommend to contact my friend Juan Pablo Gonzalez de la Vega. He is probably the person with more knowledge of Andalussian herpetofauna
