Occurrence of Lucilla scintilla (R.T. Lowe, 1852) and Lucilla singleyana (Pilsbry, 1890) in the Czech and Slovak Republics – with remarks how to distinguish these two non-native minute snails

Previously only one species of the genus Lucilla was reported from the Czech and Slovak Republics. Since this taxon is currently considered as two distinct species (L. singleyana and L. scintilla), a revision of older Czech and Slovak records was needed. The revision of available voucher material yielded findings of both species in Slovakia, contrary to the Czech Republic where only L. scintilla has been found outdoors. Distribution and detail location of known outdoor records and identification remarks, supplemented with pictures of the shells, are included in this paper.
