First record of Chondrina avenacea (Bruguière, 1792) the threatened species (in IUCN red list) in Turkey: shell morphology and distribution

Abstract :

The purpose of the study is to draw attention to the existence of the threatened species C. avenacea (Bruguière, 1792) (Gastropoda: Pulmonata), a new record for the fauna of Turkey, and to describe the shell morphology and distribution. The species is in the international union for conservation of nature (IUCN) Red List of threatened species (least concern category). The snail samples were collected from the excavation site in the vicinity of the ancient city of Priene, located near the village of Güllübahçe in Söke (Aydın, Turkey). It is a rather small species of snail, averaging 4˗5 mm in height and 1.5 mm in diameter. The shell consists of 6 to 7 convex whorls with deep sutures and is fusiform with a conical spire, solid reddish brown to dark-grey, a little glossy, smooth or with faint irregular growth ridges. The aperture of the shell is ovoid and narrowed in adults, usually with 6 teeth (1 angular, 1 parietal, 1 columellar, 1 supracolumellar, and 2 palatal teeth). C. avenacea is distributed in the Palaearctic region. The general distribution of the snail has been reported in western and southern Europe to Bulgaria; also in the mountains of the Caucasus and Crimea. It prefers to live in dry open habitats, characteristically on limestone rock surfaces and walls. It is estimated that it can be detected in the Marmara and other regions of the Aegean, with future research and their populations must be protected.
