37. Valvata piscinalis (O. F. Müller, 1774)

Findings in Serbia.

Valvata piscinalis . Hesse (1929); Jaeckel et al. (1958); Tomić (1959); Frank et al. (1990); Karaman (2001, 2005); Paunović et al. (2005, 2007a); Karaman & Karaman, (2007); Marković et al. (2013); Martinović-Vitanović et al. 2013; Novaković (2013, pers. comm. 2015).

Common name. European valve snail, European stream Valvata .

Morphology. Minute snails up to 6 mm long/wide. Helicoid shell is yellow, green, brown or whitish, with variable height. Umbilicus is open, aperture is circular, but slightly angulated at the top. For more details see Welter-Schultes (2012. 44, figure on the top of the page).

Distribution and ecology. European species, found in Armenia, Turkey and Iran as well ( Glöer 2019). It prefers muddy substrate of slow–flowing rivers, tolerating lower carbonates and soil levels ( Welter-Schultes 2012). In Serbia most findings are from the Danube River.Apart from the Danube, more recently it was recorded in the Velika Morava and Zapadna Morava Rivers, and in Plazović River.

Other remarks. Glöer (2019) recognizes two morphological forms as subspecies, viz., Valvata p. discors Westerlund, 1886 and V. p. piscinalis (O. F. Müller, 1774, but their taxonomic status remains unclear. On the IUCN Red List it has been assessed as LC ( Seddon 2011 k).
