Phylogenetic relation among lizards from the Lacertidae family (modified from⁶⁷) included in the present study. (A) photo of a male Podarcis muralis with visible femoral gland secretions protruding from the left hindlimb (white arrow). (B) particular of the cloacal region of a male P. muralis showing the series of femoral pores and yellowish secretions along the thigh—photos by MM. (C) phylogenetic tree built on 246 out of 373 currently recognized species belonging to the Lacertidae family⁶⁸; subfamilies are indicated; the wall lizard group (genus Podarcis) is in black; the species included in the current study are in red. (D) subtree of the wall lizards included in the phylogeny, with the eight species considered in the present study in red; MYA = million years ago.
