Galba truncatula (O.F. Müller, 1774) Findings in Serbia . Lymnaea truncatula : Hesse (1929) ; Jaeckel et al. (1958) ; Tomić (1959) ; Simić (1996) ; Karaman & Živić (2001) . Lymnaea ( Galba ) truncatula : Karaman (2001). Galba truncatula : Frank et al. (1990) ; Karaman & Karaman (2007) ; Gojšina (2021 pers. comm.). Common name . Dwarf mud snail, dwarf pond snail. Morphology . Small-sized snail (conical shell up to 9 mm long/high). Shell is striated, with 5–6 step-like whorls. Aperture is oval, umbilicus is open and deep. For more details see Welter-Schultes (2012: 49 , figure at the bottom of the page). Distribution and ecology . Holarctic species. Amphibious semi-terrestrial snail preferring small water bodies (meadows, ponds, marshes, brooks) and temporal habitats ( Trouve et al 2005 ; Welter-Schultes 2012 ; Dreyfuss et al . 2015 ). Fairly scarce findings in Serbia include the Danube River, and few smaller watercourses (Vlasina, Moravica and Veternica Rivers, Kudoški canal) and Obedska bara Wetland. Other remarks . Shell morphology can be very variable, particularly in regard to spire height. It could be misidentified as degenerated forms of Stagnicola palustris (O.F. Müller, 1774) ( Glöer 2019 ) . In Europe, it is known as an intermediate host for trematodes ( Fascicola hepatica and others) thus serving as a disease vector (details in Dreyfuss et al 2015 ). In some habitats with low population densities, or even individual presence of snails, selffertilization is common ( Trouve et al . 2005 ). On the IUCN Red List it has been assessed as LC ( Van Damme & Kebapçý 2011 a ). Genus Stagnicola Jeffreys, 1830
