good observation Palex. Helmeteds, for one things, are a Tarentola species. They used to Geckonia, but that arrangement makes Tarentola paraphyletic (phylogenetically uniformative). Additionally, Tarentola and Chondrodactylus bibroni (formerly Pachydactylus) are both part of the same radiation of geckos. Tarentola is more basal (towards the root on a evolutionary tree) than Chondrodactylus.
