The shells, anatomy and distribution of two species of Vitrea, one new and both endemic to Ibiza, are described. V. striata nov. is characterized by a strongly striate, perforate shell with shouldered whorls and a step-like spire. The vagina is surrounded by a gland in the middle third and the spermatheca is long and cylindrical. It is only known from Cala Sant Vicens. V. gasulli Riedel & Paul has a smooth perforate shell with more evenly rounded but also somewhat shouldered whorls, a vagina surrounded by a gland near its apex and an elongate pyriform spermatheca. V. gasulli is common and widespread in Ibiza.
