ABSTRACT
Received: 04th January 2025 Accepted: 09th January 2025 Online: 10th January 2025
The article contains scientific information about eco-geographical characteristics, biotopes of land molluscs Soda Turanena.
KEYWORDS
Stones, slopes, dry steppe, ecological and geographical, ridge, vegetation, shrubs, widespread.
The list of species of land mollusks of Central Asia in the guide has increased significantly compared to the list in the publication by A.A. Shileiko (1978, 1984), M.M. Likharev and A.I. Viktor (1980), K.K. Uvaliyev (1990), A. Pazilov, D.A. Azimov (2003). This happened both due to the inclusion of a number of species new to the fauna of Central Asia, and due to the revision of the taxonomic position of some forms that were previously considered subspecies, but are now considered independent. Therefore, we consider it necessary to provide a more complete eco-geographical description of the malacofauna of the studied region as a basis for further discussion of the data provided.
Genus Turanena Lindholm, 1922
Subgenus Turanena Schileyko and Moiseeva, 1995
1. Turanena scalaris(Naegele, 1902). Rice. 1,A.
Central Asian species. Distributed in Southern Armenia, according to I.M. Likharev (1952) outside the territory of the CIS - Iranian Azerbaijan. We first discovered several specimens of empty shells in the Baysuntau ridge.
Ecology. It is found in the mountain-steppe zone, living in cracks in rocky screes.
Subgenus Asuranena Schileyko and Moiseeva, 1995
2. Turanena (Asuranena) herzi(O. Boettger, 1889). Rice. 1,B.
Near-Asian species. Widespread. South-eastern slopes of Elbrus and the Iranian plateau (Biggs, 1962), south-western part of Turkmenistan (Shileiko, 1984). We first discovered them on the Babatag ridge.
Ecology. Lives on dry rocks.
3. Turanena(Asuranena) martensiana(Ancey, 1886). Fig. 1,B.
Central Asian species. The species range covers the Chatkal, Alai, Talas, Pskem, Zailiysky, Karatau, Kungesky, Tersky ridges. We found it in the Molguzar mountains.

4. Turanena (Asuranena) leptogyra (Lindholm, 1927). Fig. 2,A.
Central Asian species. Distributed in the Western Tien Shan.
Ecology. Found at altitude2500 mabove sea level. It lives on open mountain slopes with dry steppe vegetation, under rocks and in scree.
5. Turanena (Asuranena) tenuispira (Schileyko, 1984). Rice. 2,B.
Central Asian species. Distributed on the Fergana and Zailiysky ranges. We found it on the Fergana range near the Big Waterfall (Arslonbob) and the Kara-Bulak gorge.
Ecology. It is found in the subalpine and alpine zones. It lives on rocks with bushes and under stones. Apparently, it does not descend below the subalpine belt.
6. Turanena( Asuranena) albolimbata (Lindholm, 1927).Fig. 2,B.
Central Asian species. Distributed in places in the Chatkal and Kyrgyz ranges
Ecology. Found at an altitude of 1800-2500 m. above sea level. Lives in screes and on
rocks.
7. Turanena (Asuranena) conicula (Martens, 1882).Fig. 2,G.
Mountain-Asian species. The range of the species covers Kuldzha (Western China), the Alay and Zarafshan ranges, as well as the Terskey Alatau ranges. We found it on the Zarafshan range, near the village of Farob (Tajikistan).
Ecology. Found at an altitude of 1750-2500 mabove sea level. It lives in very dry rocky areas.
