ABSTRACT: The Tlemcen region is located in north-western
Algeria and is characterized by a semi-arid bioclimate. An approach to the
diversity of the malacofauna associated with Salvia officinalis was carried out in three stations belonging to this area from February to June
2015. The specific richness of the Gastropods is 9 divided into three families:
Milacidae, Helicidae and Subulinidae. The second includes two subfamilies
including that of Helicinae and that of Helicellinae. Two species are constant,
01 is incidental and the 06 others are very accidental. The relative importance
of snails fluctuates according to the stations and according to the months and
the seasons. In winter, in the first station the malacological richness is
equal to 6. In February, the specific richness is relatively important in the
2nd station with a value equal to 7. Milax nigricans (Milacidae)
has a frequency of 10% in station 1 and has a density of 0.1 in this same
station. It is absent in the other two stations. Euparypha pisana has a frequency of 60% in station 3 and an abundance of 0.57 in this same
station.
