Molecular phylogeny, which is a potentially powerful tool for the conservation of biodiversity, provides essential evidence for setting conservation priorities on several taxa. Phylogenetic analyses can identify cryptic, genetically distinct lineages as well as non-distinctive lineages earlier perceived as separate taxa. The herpetofauna of the east Mediterranean region, which could be considered as one of nature’s most intensively active evolutionary laboratories, serves as an excellent example. Phylogenetic analyses on several lacertid taxa of this area have revealed cases of hidden diversity, paraphyly, new species and new endemics. In several cases the presence of cryptic species (Podarcis levendis, P. cretensis), species with very restricted distributions (P. gaigeae, P. milensis), paraphyletic (M. guttulta) or even polyphyletic species (O. elegans) were revealed. Such cases impose a considerable revision of the taxonomic views and conservation priorities. Based on these findings, many questions have been answered and certainly new ones have emerged, contributing not only to our knowledge on the east Mediterranean herpetofauna, but to broader issues of conservation biology, prioritizing conservation efforts and enhancing the need for a new multidisciplinary and innovative tool for screening and re-evaluating biodiversity.

(2018) - Systematics of the Mesalina guttulata species complex (Squamata: Lacertidae) from Arabia with the description of two new species. - Zootaxa, 4429 (3): 513-547. × Mesalina are small diurnal lacertid lizards inhabiting arid areas from North Africa to northwestern India. Previous phylo- genetic studies have shown the existence of several species complexes within the genus, some of them with high levels of undiscovered diversity. In the present study, we carry out an integrative systematic revision of the Mesalina guttulata spe- cies complex using both molecular and morphological data from across its entire distribution range in North Africa, the Middle East and Arabia. The results of the genetic analyses indicate that M. guttulata and M. bahaeldini are two allopatric sister taxa separated by the Suez Canal and that the species complex includes a further three unnamed deep phylogenetic lineages, two of them restricted to southern and southwestern Arabia and described herein as Mesalina austroarabica sp. nov. and Mesalina arnoldi sp. nov., respectively. As a result of the lack of enough material, the third deep lineage, distrib- uted across Kuwait, Saudi Arabia and Jordan, is provisionally left undescribed. The two newly described species are char- acterized by their size, scale counts and tail coloration, as well as differences at the three mitochondrial and one nuclear gene analyzed in the present study.
