General description and taxonomical remarks

Class: Reptilia
Order: Squamata
Family: Lacertidae
Genus: Dinarolacerta (Arnold, Arribas & Carranza, 2007)
Dinarolacerta mosorensis (Kolombatović, 1886) – Mosor rock lizard
Dinarolacerta montenegrina (Ljubisavljević, Arribas, Džukić & Carranza, 2007) – Prokletije rock lizard

The genus Dinarolacerta comprises two species: Dinarolacerta mosorensis (Kolombatović, 1886) – Mosor rock lizard and D. montenegrina (Ljubisavljević, Arribas, Džukić & Carranza, 2007) – Prokletije rock lizard. The Mosor rock lizard was formerly classified as a species of Archaeolacerta (Mertens, 1921), which was considered as a subgenus of Lacerta or as a distinct genus (Arribas, 1999; Mayer & Arribas, 2003). In 2007, Arnold and co-workers put it in newly described genus Dinarolacerata (Arnold et al., 2007). The specific status of the Prokletije rock lizard was established in 2007. according to clear genetic differences and some morphological distinctiveness in regard to the other rock lizards (Ljubisavljević et al., 2007a). Formerly, it was believed that it presents a small isolated population of the Mosor rock lizard on the eastern border of the species range (Džukić et al., 1997).
Dinarolacerta species are distinctly flattened small lacertid lizards (up to 7 cm from snout to vent and 22 cm of total length) with long head, pointed snout and long slender tail that is about 2/3 of body length (Bischoff, 1984; Arnold & Ovenden, 2002). Dorsal body scales are roundish, flattened and unkeeled (Radovanović, 1951; Arnold et al., 2007). Dorsal side is dark grey, grey-brown, olive or brown with dark spotting or mottling, or spots are limited to center of the back. Flanks are often darker than back (Arnold et al., 2007). Sometimes unmarked specimens may occur. In adults the underside is whithish, grey, yelowish, deep yellow or orange, unspotted (Arnold & Ovenden, 2002). Blue spots may be present on external row of ventral scales (Arnold et al., 2007). Males are larger than females (Ljubisavljević et al., 2008). Juveniles are similar to adults, but always with whithish or grey belly, and sometimes with blue or greenish tail (Bischoff, 1984).
The two Dinarolacerta species are genetically distinct, but morphologically are similar. The morphological differences are mainly restricted to body size, number of certain head scales and dorsal pattern. Prokletije rock lizard differs from the Mosor rock lizard by its smaller size (up to 6.4 cm from snout to vent and 18 cm of total length), by usually having only one postnasal scale, smaller number of temporal scales, greater number of ventral scales and more banded dorsal pattern than the Mosor rock lizard (Ljubisavljević et al., 2007a). The details of scaling and other morphological traits can be found in Bischoff (1984), Arnold & Ovenden (2002), Arnold et al. (2007) and Ljubisavljević et al. (2007).
