Bradybaena
 (Beck, 1837) 
–
 
genera
 
B.scythica
(Westerlund, 1898) – occurs in mountainous areas, at an altitude 
of 2100-3500 m above sea level. It inhabits shrubs, in talus under large stones, as 
well as in floodplain areas with moderate humidity. 
B.lantzi
(Lindholm, 1927) –
the species is generally hygromesophilic; forms 
the greatest density on high-grass, medium-mountain meadows, along the banks of 
rivers and streams, in narrow shady gorges. In such places there is, as it were, the 
core of the population, from which individual individuals migrate even to open 
slopes, where, however, they stay in the daytime under stones, in talus and in 
cracks in rocks. 
B.phaeozona
(Martens, 1874) – inhabits almost all types of biotopes. The 
greatest density of snails is formed under bushes and in coarse talus. During 
summer hibernation, they burrow into the soil or go deep under stones, hibernation 
is carried out mainly in the soil at a depth of 10 cm. 
B.almaatini
(Skwortzov, 1940) – lives at altitudes of 800 - 2300 m above sea 
level, on rocks, in coarse talus, in bushes and in dense grass of steppe slopes. 
B.dichrozona
(Martens, 1885) – found mainly in mountainous areas. It lives 
among bushes, in talus and cracks in rocks. 
B.fedtschenkoi
(Martens, 1874) – lives under stones, among rotting plants 
and under the roots of perennial grasses and shrubs. 
B.cavimargo cavimargo
(Martens, 1879) – occurs at an altitude of 1500 m 
above sea level, on the southern slopes. Inhabits the steppe slopes, prefers fine-
grained talus. 
B.sinistrorosa
(Tzwetkov, 1938) – occurs at an altitude of 2500 m above sea 
level, among the bushes. 
B.alaica
(Kuznetsov, 1998) – lives in the zone of juniper forests on open 
slopes, in talus at the foot of limestone rocks. 
When the studied species were analyzed zoogeographically, they were 
distributed as follows [1, 286]: 
Highland Asian species: 
P.semenovi, B.phaeozona, B.cavimargo cavimargo
Central Asian species: 
B.scythica
, 
B.lantzi, B.almaatini, B.dichrozona, 
B.fedtschenkoi, B.sinistrorosa, B.alaica.
All the species of the 
Bradybaenidae 
family that we have listed are 
considered endemic to Central Asia, so it is important to take measures to preserve 
them. It has been observed that most mollusks are considered to be mesophilic 
species that love moisture and live mainly in mountainous areas. In recent years,

the anthropogenic impact on the mountainous regions of the Fergana Valley has 
been increasing, which is the reason for the decline in the populations of many 
species of plants and animals. By preserving the habitat of mollusks, it is possible 
to preserve their biodiversity.
