The lizard fauna of Jordan is very diverse and forms 55.5% of the terrestrial herpetofauna of the country. Lizard species of Arabian origin form the highest percentage (43%) of the lizards, followed by Saharo-Sindian (35%), Palaearctic (20%) and only 2% with Afrotropical affinities. 69.1% of the lizard species inhabit two ecozones: Badia (Eastern Desert); and Wadi Araba and Wadi Rum. The Badia may form the focal point for the evolution of certain Acanthodactylus species. Jordan forms the southernmost limit of the distribution of some Palaearctic species (i.e. Lacerta media, L. laevis, Pseudopus apodus) and they inhabit the Mediterranean ecozone. The presence of diverse habitats in Jordan allowed certain allopatric congeneric species of the genus Ptyodactylus to live in isolation from one another. Southern Jordan and Wadi Rum are part of the Levantine land bridge and act as a “biogeographical filter”. Most of the species found in Wadi Rum are of Arabian affinities and their distribution does not extend towards the west.

The checklist is based primarily on extensive collections made by the United States Naval Medical Research Unit No. 3 (NAMRU-3) in Egypt. Forms listed are those that are known or expected to occur in Egypt (including Sinai), and those that have been reported from Egypt without further verification. The systematic lists contain original citations, references to major faunal works, and the most recent reviews of each particular group. From the 3.424 specimens obtained, adequate distributional data are now available for most forms in Egypt. Maps showing collecting localities for each species are also presented for use in future sympatric and ecological studies.

Acanthodactylus lizards are among the most diverse and widespread diurnal reptiles in the arid regions spanning from North Africa across to western India. Acanthodactylus constitutes the most species-rich genus in the family Lacertidae, with over 40 recognized species inhabiting a wide variety of dry habitats. The genus has seldom undergone taxonomic revisions, and although there are a number of described species and species-groups, their boundaries as well as their interspecific relationships are largely unresolved. We constructed a multilocus phylogeny, combining data from two mitochondrial (12S, cytb) and three nuclear (MC1R, ACM4, c-mos) markers for 302 individuals belonging to 36 known species, providing the first large-scale time-calibrated molecular phylogeny of the genus. We evaluated phylogenetic relationships between and within species-groups, and assessed Acanthodactylus biogeography across its known range. Acanthodactylus cladogenesis is estimated to have originated in Africa due to vicariance and dispersal events from the Oligocene onwards. Radiation started with the separation into three clades: the Western and scutellatus clades largely distributed in North Africa, and the Eastern clade occurring mostly from Arabia to south-west Asia. Most Acanthodactylus species diverged during the Miocene, possibly as a result of regional geological instability and climatic changes. We support most of the current taxonomic classifications and phylogenetic relationships, and provide genetic validity for most species. We reveal a new distinct blanfordii species-group, suggest new phylogenetic positions (A. hardyi, A. masirae), and synonymize several species and subspecies (A. lineomaculatus, A. boskianus khattensis and A. b. nigeriensis) with their phylogenetically closely-related species. We recommend a thorough systematic revision of taxa exhibiting high levels of intraspecific variability as well as clear evidence of phylogenetic complexity such as A. guineensis, A. grandis, A. dumerilii, and A. senegalensis and the pardalis and erythrurus species-groups.
