First live imagery, morphological insights, and new locations of the near-threatened endemic microsnail Sheitanok amidicus (Caenogastropoda:Hydrobiidae) from southeast Turkey. Molluscan Research, 1-8.1323-5818https://www.tandfonline.com/doi/full/10.1080/13235818.2023.2233121https://hdl.handle.net/11468/12551This study presents new insights into the near-threatened endemic microsnailSheitanokamidicus(Schütt &Şeşen, 1991), shedding light on its distribution and morphologicalcharacteristics, which have never been documented alive. Surveys conducted in 2023uncovered two previously unknown localities where the species thrives: stenothermicsprings in Tavşantepe village and a private farm in Diyarbakır, Turkey. The snail has whitish-grey body tissue, tentacles with an average length of 0.3 mm, and a foot extending up to2 mm with grey dots on the upper part. The oval-shaped operculum has an average heightand width of 0.4 and 0.3 mm, respectively. The shell width and height is 1.0 mm and0.7 mm, respectively. The snail has unique features including an orange operculum, heart-shaped blackish mouth parts and two blackish eyes at the base of its tentacles. Previously,the species was known to inhabit seven locations in Southeast Turkey. Its near-threatenedstatus on the IUCN Red List highlights the urgency of conservation efforts. The identificationof these new locations provides hope for reducing the risk of extinction forS. amidicus.Additionally, describing the snail’s external characteristics would aid in systematicclassification of newly found species within this monotypic genus.eninfo:eu-repo/semantics/closedAccessFreshwater snailMonotypic genusMorphological featuresStenothermic springsArticleEarly Access18WOS:0010297607000012-s2.0-8516530353410.1080/13235818.2023.2233121Q3N/A
