Agamidae View in CoL View at ENA ( Fig. 11A–C View Figure 11 )

Laudakia stellio View in CoL has a slightly medially curved anterior premaxillary process, provided with a roughly straight (slightly concave in juveniles) anterior margin. Adults lack an anterolateral process, whereas a little developed one can be seen in juveniles. The pointed anteromedial process, on the other hand, is distinctly developed in the dorsal direction ( Fig. 11A, B View Figure 11 ). The posterior process is long and pointed, having a moderately deep groove for the articulation of the jugal on its dorsal surface. A strong spur is present on its dorsal margin; the spur can be posteriorly rounded or pointed and projects in the posterior direction. The maxilla carries two large, subpleurodont, stocky, conical and monocuspid teeth at its anterior end ( Fig. 11C View Figure 11 ). Acrodont and triangular teeth are present posteriorly. According to Smith et al. (2016), the second subpleurodont tooth is larger than the first one in males of Laudakia stellio View in CoL . Acrodont teeth are closely spaced and extend towards the medial surface of the alveolar shelf ( Fig. 11B View Figure 11 ). They can also present small accessory cusps located anteriorly and posteriorly to the main one. The size of the acrodont teeth increases posteriorly, with the anteriormost being very small. In juveniles there is only one smaller subpleurodont tooth anteriorly and the acrodont teeth are large for the entire length of the tooth row. Only the posterior fourth (fifth in juveniles) of the alveolar border does not bear teeth. The anterior and posterior openings of the superior alveolar canal are moderately wide and subcircular. We observed four or five ventrolateral foramina on the otherwise smooth lateral surface, but Smith et al. (2016) reported six of them in the left maxilla of one of the specimens they examined [see supplementary information in Smith et al. (2016)]. The facial process is triangular in lateral view. The anterior margin is roughly straight, whereas the posterior one is strongly concave. The dorsal end is bifid, with two wide and rounded projections. The anterior one is longer than the posterior one. The whole anterior margin of the process, anterior projection included, bends medially ( Fig. 11B View Figure 11 ). Both the lateral and the medial surface of the process are smooth. Including the subpleurodont ones, a number of nine to 18 tooth positions is present [ten to 15, according to Siebenrock (1895)]. The alveolar border can measure from 5.5 mm to 15 mm in maximum length.
