A new record of the green sea turtle Chelonia mydas (Linnaeus, 1758) occurrence in the eastern part of the Black sea, on the territory of Republic of Abkhazia, is reported.


The paper presents seven new records of the diadem snake Spalerosophis diadema in Kazakhstan in 2016 - 2017. It is proposed to include this species into the Red Data Book of Kazakhstan.


In June 2017 on the territory of the Southern Kazakhstan region, on the right bank of the Syrdariya River, in the vicinities of the Darbaza mountain, under a nest of the long-legged buzzard (Buteo rufinus) the remains of 5 dead individuals of Schneider's skink (Eumeces schneideri) were found. This finding is located 110 km north-west from the nearest known habitation place of Schneider's skink on the Chatkal Range and allows us to include it into the herpetofauna list of Kazakhstan, and also to considerably expand our representations of its propagation north.

On Eggs Re-Laying of Greenbelly Lizards from the Darevskia (Chlorogaster) Complex (Reptilia, Lacertidae)

The paper discusses cases of eggs re-laying in two lizard species from the Darevskia (chlorogaster) complex. A male and a female of D. Chlorogaster were captured on 22 March, 2016 in the Gilan province (Iran), and she subsequently laid eggs on 29 May (4 eggs) and 5 July (4 ones). The eggs had length of 10.4–12.8 mm, the width of 6.1–6.5 mm, and the weight of 0.240–0.340 g. Young lizards came out from seven eggs after 52–55 days of incubation. The body length of these newborn lizards was 22.9–27.8 mm, the tail length was 38.5–46.5 mm, and the weight was 0.330–0.460 g.

Current Distribution and Some Features of the Biology of the Common Lizard – Zootoca vivipara (Lichtenstein, 1823) (Lacertidae, Reptilia) in the Saratov Region

On the territory of the Saratov region, the populations of viviparous lizards mainly inhabit the river valleys of the Don basin. Most populations were found along the sides of lake basins. In the conditions of the drying up of floodplain lakes, some populations have degraded while the others have moved to river-bed biotopes. The reduction in the number of local populations has led to their increased disconnection.

Notes on the Snakes of the Northern Caucasus

The paper provides new information on the distribution of rare and endangered snakes over the Stavropol Region, namely, Eryx jaculus, Dolichophis caspius, Elaphe sauromates, and Platyceps najadum.

Daily Diet of Pelobates fuscus (Pelobatidae, Amphibia) in the Khoper River Floodplain (Saratov Region)

The daily diet of Pelobates fuscus in local populations in the Khoper river floodplain is considered. The absence of gender differences in their daily diet is shown. Most of P. fuscus prey is made up of animals weighing 10–25 mg and having body lengths of 8–18 mm. Hymenoptera (70.8%) and Coleoptera (52.1%) predominate by the number of specimens and by biomass, respectively. The number of daily caught invertebrates usually does not exceed 15. The lowest feed consumption is in April and October, while the highest one is in the summer months.

Rediscovery of the Caucasian Smooth Newt, Lissotriton lantzi (Wolterstorff, 1914) (Salamandridae, Amphibia) in North Ossetia–Alania

Lantz’s newt, or the Caucasian smooth newt, Lissotriton lantzi, is an endemic species for the Caucasian mountain-forest belt. In North Ossetia–Alania, only 4 findings of this newt are known in the Prigorodniy, Alagirskiy and Irafskiy districts. Since 1983, there has been no new information about any findings of L. lantzi in this region. On August 4, 2020, L. lantzi larvae were caught in a lake on the left shore of the Urukh River in the Irafskiy district. Newts live here in a beech forest at an altitude of 810 m. The authors assume that L.

Present distribution of the common frog, Rana temporaria and the moor frog, R. arvalis (Amphibia, Anura) in the “old” Moscow

The common frog (Rana temporaria) and the moor frog (R. arvalis) lived in all green areas of Moscow until the end of the 20th century. The reduction in the area of woody vegetation, the destruction of breeding sites and introduction of the invasive fish Perccottus glenii contributed to the extinction of these amphibians in most of the city. The paper provides information on the distribution of brown frogs in Moscow based on the results of monitoring in 2020. R.
