Lacertidae View in CoL View at ENA ( Fig. 8E–U View Figure 8 )
The premaxilla of lacertids present a long (usually shorter in Lacerta , Ti. lepidus and Z. vivipara ; Fig. 8M, N, U View Figure 8 ) and pointed ascending nasal process, which can be narrow with parallel lateral margins ( Algyroides , Anatololacerta anatolica , Ar. bedriagae , Da. oxycephala , Darevskia , Di. mosorensis , H. graeca , I. aranica , I. aurelioi , I. bonnali , I. horvathi , I. martinezricai , Ophisops elegans , Podarcis and Psammodromus ; Fig. 8Q, R View Figure 8 ), arrow-shaped ( E. arguta , I. cyreni , I. galani and I. monticola ; Fig. 8I, J View Figure 8 ), stocky and leaf-shaped ( Lacerta , Ti. lepidus and Z. vivipara ; Fig. 8M, N, U View Figure 8 ) or moderately narrow and slightly leaf-shaped at the dorsal end ( Ac. erythrurus ; Fig. 8E, F View Figure 8 ) in adults. Juveniles of all species have the first morphology and then develop the other ones during ontogeny. Some degree of variability is present in Al. nigropunctatus , Da. oxycephala , Di. mosorensis and Po. muralis , because some adult or subadult specimens (e.g. Al. nigropunctatus MDHC 242, Da. oxycephala NHMW 629, Di. mosorensis NHMW 660 and Po. muralis MDHC 6) develop a more triangular or rather sagittate morphology. Similarly, MDHC 311, a large and probably old specimen of Po. muralis , displays a more leaf-shaped nasal process. The septonasal crest is moderately developed and covers almost the entire length of the process, except for some specimens of Al. moreoticus , Al. nigropunctatus , Lacerta trilineata and Z. vivipara , in which the crest is less developed in its distal-half ( Fig. 8U View Figure 8 ). In adults of Al. nigropunctatus , I. cyreni , I. monticola , Lacerta , Po. melisellensis , Po. muralis , Po. siculus , Po. tauricus , Po. tiliguerta , Po. waglerianus , Psammodromus algirus , Ti. lepidus and maybe also Po. filfolensis , a dermal ornamentation can be present on the dorsal-half of the external surface of the nasal process ( Fig. 8M, P, Q View Figure 8 ). The notch between the palatal processes is deep, wide and V-shaped ( Fig. 8H View Figure 8 ). Teeth are pleurodont, cylindrical, slender and monocuspid [morphotype B sensu Kosma (2004)], but adults of Lacerta , Po. siculus and Ti. lepidus have some bicuspid teeth [morphotype G sensu Kosma (2004)] also ( Figs 8M, N View Figure 8 , 10 View Figure 10 ). Some specimens of I. monticola can have a second pair of foramina of the longitudinal canals ( Barahona, 1996; Fig. 8I View Figure 8 ). Acanthodactylus erythrurus UAM.R.ACVII ( Fig. 8E View Figure 8 ) and Po. muralis MDHC 6 have two accessory foramina on the base of the ascending nasal process too. Number of tooth positions, together with measurements of the width of the alveolar plate, are given in the Supporting Information 3.
