| Abstract | La région de Tlemcen est située dans le Nord-ouest algérien. Le climat à tendance aride, entraîne une dégradation de la végétation en formation ouverte, où sont retrouvés le doum et le diss. D’autres espèces aromatiques sont considérées : le romarin, le thym, le marrubium et le ciste à feuilles de sauge. Par leurs caractères morphologiques et botaniques, les trois premières espèces aromatiques appartiennent à lafamille des Labiées, la quatrième à la famille des Cistacées. Nous nous proposons de réaliser une approche de la diversité de la malacofaune recensée sur ces différentes plantes à importance médicinale. Pour celà,un inventaire est réalisé dans différentes stations. La richesse malacologique sur le thym est estimée à 19, celle sur le romarin à 18, celle sur le ciste à feuilles de sauge à 11 et seulement à 7 sur le marrube. Elle comprend 4 familles à savoir les Milacidae, les Sphincterochilidae, les Helicidae et les Subulinidae. Les Milacidae ne sont représentés que dans les stations à marrube, par contre les Sphincterochilidae sont absents dans ces mêmes stations. La famille des Subulinidae comporte une seule espèce. Il s’agit de Rumina decollata. Pour ce qui est de la famille des Helicidae, la plus riche spécifiquement comporte 2 sousfamilles : celles des Helicinae et des Helicellinae. La 1ère sous-famille compte 11 espèces sur le thym, 10 espèces sur le romarin et 7 sur le ciste. La 2ème sous-famille comprend respectivement 6 espèces sur le thym et le romarin, 2 sur le ciste et une seule sur le marrube. Aussi nous essayons de rechercher les espèces malacologiques spécifiques à chacune de ces plantes et les espèces qui leur sont communes. En dernier, la répartition verticale des gastéropodes est donnée.Mots-clés : faune malacologique, plantes médicinales, richesse spécifique, distribution verticale, région de Tlemcen. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
