Solatopupa juliana ( Issel, 1866)

Type locality: Italy, province of Pisa , San Giuliano .

Distribution.—According to unpublished data, kindly put at our disposal by Dr. M. Bodon and Prof. Dr. F. Giusti, this Italian endemic species is known from the extreme southeastern part of the province of La Spezia in Liguria, many localities in Toscana, and very few places in Lazio, as far south as the province of Latina.

Notes.— Boata (1988, 1991) demonstrated that S. juliana is most closely related to the partly sympatric S. pallida , although it is conchologically very similar to S. similis . The sibling species S. juliana and S. similis both occur in the coastal area of Liguria, but never sympatrically. They are geographically separated by a gap of over 60 km.
