For comparison with the fauna of China, the following territories were selected: North Eurasia, Iran and different countries of South and Southeast Asia. There are 49 agamid species in China, comprising 12 genera and 4 subfamilies. Annotated check-list and identification keys to genera are provided. Among the 49 species of agamids present in China, the percent of endemic species is relatively high (22 species; 45%). Endemic species refer to 4 genera with the genus Japalura having the most, 10 of 14 species, proceeded by members of Tibetan Plateau lineage of Phrynocephalus, 8 of 12 species, and Calotes with 1 species and Laudakia with 3.

Within Acrodonta, there are 7 lines (Amphibolurinae, Leiolepidinae, Draconinae monophyletic lineages: 1) Chamaeleo (Chamaeleonidae), and Agaminae) in the fauna of Asian agamid lizards. 2) Uromastyx, 3) Leiolepis, 4) Hydrosaurus, 5) Southeast For comparing agamid lizard species diversity from Asian group of genera, 6) Afro-southwest-Asian group of China, Iran, and North Eurasia (former Soviet Union genera, and 7) Australo-New Guinean group of genera + Mongolia), different regions of South and Southeast (including Physignathus cocincinus). Such interpretation Asia were selected. Differentiated diagnoses of agamid is based on the results of the integration of morphological lizards of China are provided which allow to identify (Moody, 1980) and molecular data (Macey et al., 2000). their taxonomic position at generic level. We use our Within the family Agamidae there are six major clades own data as well as published results from studies on (subfamilies): 1) Uromastycinae Theobald, 1868 with Oriental and Palearctic agamid lizards (Moody, 1980; the genus Uromastyx; 2) Leiolepidinae Fitzinger, 1843 Zhao and Adler, 1993) to develop a dichotomous key of with genus Leiolepis; 3) Amphibolurinae Wagler, the genera Acanthosaura (Orlov et al., 2006; Ananjeva et 1830 with all Australian and New Guinean species as al., 2008; Wood et al., 2009, 2010), Draco (Inger, 1983; Musters, 1983; McGuire and Heang, 2001), Japalura * Corresponding author: Prof. Natalia B.
