to now, 12 snail species  have been determinted as a intermediate host (Helicella candicans, Helicopsis krynickii, Trochoidea pyramiadata, Monacha carthusiana, Cochlicella acuta, Helicella itala, Cernuella virgata, Helicopsis protea, Helicella obvia, Helix aspersa, Helix lucorum,  Chondrus tournefortianus)  in Turkey.

Unfortunately, classification mistakes are made by the fact that the host, intermediate host and parasites are from separate groups of animals. Particularly in relation to intermediate hosts , these are:  Helicella candicans is synonim of Xerolenta obvia. Probably the researchers have noted snail belong to this species  from old and invalid literatures. Its same for the Helicella obvia, its synonim of the Xerolenta obvia. Helicopsis krynickii, Its synonim of the Xeropicta krynickii; Monacha carthusiana  is also synonim of  Monacha claustralis. Helicella itala,  never has been found in Turkey. Probably reason of only morphological description. Because this species distributing in western Europe.  Helicopsis protea never has been found in Turkey.  Probably reason of only morphological description. Helicella obvia is synonim of  Xerolenta obvia.
