Parvilacerta parva belongs to the genus of the dwarf lizards ( Parvilacerta ). The specific epithet parva comes from Latin and means small .
distribution and habitat
The lizard lives in the eastern and central areas of the Asian part of Turkey, as well as parts of Armenia . It prefers dry and mountainous regions with sparse vegetation at altitudes of 800 to 2,400 meters, but also occurs on areas grazed by cattle.
features
Parvilacerta parva reaches a head-trunk length of 6.5 cm; adult males are only slightly longer than female specimens. The animals have gray and light brown backs with black and white spots. Occipitally there are a few, sometimes united, black spots that form a black line down to the front legs. Often there are blue ocells (eye spots) in the shoulder region and often blue or green ocells in the males and whitish ocelles on the flanks of the females. The animals are lighter in the middle of the back than on the sides. The supratemporal and subocular lines are light. The ventral side is yellow-whitish, with blue or green spots in the males.
Usually 27 presacral vertebrae are found in males and 29 in females . The dorsal body scales are small and strongly keeled, about 30 to 45 in a transverse row in the middle of the body. In Parvilacerta parva two Postnasalschuppen are available. The preanal scales are small and usually surrounded by two semicircles of smaller scales.
The skull of Parvilacerta parva has some special features compared to other Palearctic real lizards . The skull is relatively large, the ossicles small. Animals with a lower jaw length of up to 11.8 mm were found.
Way of life and reproduction
These dwarf lizards appear from mid-April to late September after being frozen . During mating, the male bites into the flank and thighs of the female. Up to three clutches a year, the first in late June to early July, each contain around 2–5 eggs. Young animals appear from the end of July. The animals become sexually mature after the second winter rigor.
