The NW Aegean Sea has a complex topography, high quality waters, oligotrophic to eutrophic conditions, is connected with estuaries and wetlands, is of high ecological interest, harbours all the types of human activities and yet few researchers work on its marine biodiversity. With this study, the contribution to the knowledge of the Hellenic and Eastern Mediterranean gastropod biodiversity of the studied families is continued, and an expansion of the search in other substrates and deeper waters of the NW Aegean Sea with emphasis on the minor in size species during the period from October 2008 to January 2014.
Thirty seven species belonging to seven families (Cerithiopsidae, Fissurellidae, Phasianellidae, Scissurellidae, Siliquariidae, Skeneidae, and Triphoridae) were identified and their biodiversity was compared with the current checklists of marine gastropod molluscs for the Hellenic Seas based on previous surveys. In this collection of gastropods, one species (Emarginula decorata Deshayes, 1863) is a new alien for the Mediterranean Sea, 14 species are new for the Eastern Mediterranean Sea and 16 species are new for the Hellenic fauna (with the one above mentioned alien species included). The main identification characteristics and ecological information such as habitat, distribution, alien expansion paths to the NW Aegean Sea and origin of the species are given and discussed.
The Hellenic gastropod biodiversity of the studied families was enriched with 37 new records for the N Aegean Sea, out of which 16 are new for Greece, 14 are new for the Eastern Mediterranean Sea while one (Emarginula decorata) is a new alien for the Mediterranean Sea.
爱琴海西北部地形复杂，水质优良，营养状况从贫营养到富营养不等，与河口和湿地相连，具有很高的生态价值，承载着各种人类活动，但对其海洋生物多样性进行研究的人员却很少。通过本研究，继续为了解所研究科的希腊和东地中海腹足类生物多样性做出贡献，并在2008年10月至2014年1月期间，扩大在爱琴海西北部其他基质和更深水域的搜索范围，重点关注小型物种。
共鉴定出属于7个科（Cerithiopsidae科、Fissurellidae科、Phasianellidae科、Scissurellidae科、Siliquariidae科、Skeneidae科和Triphoridae科）的37个物种，并将它们的生物多样性与基于以往调查的希腊海域海洋腹足类软体动物现行清单进行了比较。在这组腹足类动物中，有1个物种（Emarginula decorata Deshayes，1863）是地中海新出现的外来物种，14个物种是东地中海新发现的，16个物种是希腊动物区系新发现的（包括上述外来物种）。给出并讨论了主要鉴定特征和生态信息，如栖息地、分布、向爱琴海西北部的外来扩散路径以及物种的起源。
所研究科的希腊腹足类生物多样性因爱琴海北部的37个新记录而得到丰富, 其中16个对希腊来说是新的，14个对东地中海来说是新的，而1个（Emarginula decorata）是地中海新出现的外来物种。
