Hi Matthew,
Very nice latastei individual!
I was in Huelva with many friends trying to find it in a weekend (including a couple of german "viper experts") and we found many Malpolon, Macroprotodon, Hemorrhois and Natrix maura but no vipers. My Huelva friends always tell me that is very difficult to find them. The best viper day there (probably in history!) is the day of Jeroen et al. who found 4 (or 3?) in the same day in a place where my friends have been herping thousand of times with success only few times (1-2 vipers in 1 year). In rocky places (Gredos, Burgos, Soria...) is easy to know the aprox place to look for vipers, but in Doñana all is similar and it´s more difficult...
About subspecies, Juan made many scale accounts and other morphological work with vipers, but mtDNA analysis don´t support abulensis. Brito´s team made some genetical analysis and that analysis show a complex scenario with at least 4 clades: west Iberia (Portugal, ssp."abulensis", ssp."gaditana" of Huelva and most áreas of Sierra Morena), east Iberia (east areas of Andalussia to Burgos and Catalonia), Cadiz-Malaga populations and Africa (including sp./ssp."monticola", Middle Atlas, Riff, Algeria). For more info you can read: "Deep evolutionary lineages in a Western Mediterranean snake (Vipera latastei/monticola group) and high genetic structuring in Southern Iberian populations" (Velo-Anton et al., 2012)
Cheers!
