Authors: Antipov S. A., Klenina A. A., Doronin I. V.

Detailed morphological characteristics of the populations of Coronella austriaca on the northern border of its range, in the Vladimir and Nizhny Novgorod regions, are presented. L.corp. of males and females reaches 543 mm and 601 mm, respectively. Ventr. is 166–175 and 175–189, respectively, Scd. Is 50–59 and 32–56, Lab. left/right is usually 7/7 (89.7%), Sublab. is 9/9 (72.4%), respectively.

Taxonomy, Phylogeny and Distribution of Phrynocephalus (superspecies guttatus) (Reptilia: Agamidae)

Authors: Dunayev E. A., Solovyeva E. N., Poyarkov N. A.

7 qualitative pholidosis characters were revealed, according to which the phylogenetic groups of spotted toad-headed agamas, Phrynocephalus (superspecies guttatus), reliably differ from each other, and a diagnostic key was designed based thereon for distinguishing representatives of the group. Molecular phylogenetic analysis of a fragment of the COI gene of mtDNA confirmed the differentiation of Ph. melanurus in two lineages; also Ph. incertus and Ph. kuschakewitschi stand apart with high supports. The subspecies Ph. g.

PHOLIDOSIS VARIATIONS OF THE SAND LIZARD LACERTA AGILIS (LINNAEUS, 1758) AND COMMON LIZARD ZOOTOCA VIVIPARA (LICHTENSTEIN, 1823) FROM THE WESTERN PART OF THE TATARSTAN REPUBLIC

Authors: Idrisova L. A.

The paper considers qualitative and quantitative characteristics of pholidosis variations in two lizard species, comparative analysis of these indices at both intraspecific and interspecific level is carried out. 45 and 19 types of deviations were observed in the sand lizard and common lizard respectively. Variations of the labial, supraocular and supraciliar, frontonasal, parietal, occipital and ventral scales are more common in both species. The sand lizards from the Spassky region differ from the others by some indices.
