Most probably, the type locality should be quoted as Fridrichsdal, a suburb of Copenhagen, Denmark (see Nekhaev et al. 2015 for details). Types. Lost ( Nekhaev et al. 2015 ). The taxonomic position and identity of this morphologically-peculiar species have not raised many doubts and most authors treated it more or less identically ( Hubendick 1951 ; Gloeer 2002 ; Welter-Schultes 2012 ; but see Kruglov and Starobogatov 1993b ). The results of our study well correspond to the commonly-accepted concept of M. glutinosa . Shell of this species is very fragile, semi-pellucid and, in a living animal, it is completely covered by the reflected mantle. Shell shape is almost globose, with greatly expanded aperture and very diminished spire (in some specimens, it is almost invisible). The structure of the copulatory apparatus of M. glutinosa , as is described by various authors ( Hubendick 1951 ; Kruglov and Starobogatov 1985b ; Jackiewicz 1998 ), is virtually indistinguishable from that of the genera Ampullaceana and Peregriana . However, the length of the spermathecal duct is different (long in Myxas , very short or almost absent in Ampullaceana and Peregriana ). The range of M. glutinosa covers Europe (except of the southern and northern parts), the Urals, Western and Central Siberia ( Khokhutkin et al. 2009 ; Welter-Schultes 2012 ; Vinarski et al. 2013 ).
