First record of Stagnicola montenegrinus Gloer & Pesic, 2009 (Mollusca: Gastropoda: Lymnaeidae) in Bulgaria and its taxonomic relationship to other European lymnaeids based on molecular analysis
Stagnicola montenegrinus was found in the floodplain of the river Maritza in Plovdiv. By comparison of the cyt-b sequences (fragment of 329 bp) of one of the specimens with other European Stagnicola specimens, this specimen fell in a cluster together with two sequences of S. montenegrinus from Skadar Lake, confirming the morphological determination and the first record of this species for Bulgaria. S. montenegrinus is a species closely related to S. corms. The species' occurrence is evidently not limited to the Skadar Lake region from where S. montenegrinus was originally described.
