With the aim of clarifying the taxonomical status of Helix semipicta Hidalgo, 1870 its locus typicus has been sampled intensively and the specimens collected have been compared with the syntypes deposited in the Museo Nacional de Ciencias Naturales in Madrid. Furthermore the shell and the reproductive system of Helix semipicta have been compared to specimens of Helicella cistorum (Morelet, 1845), the most similar Iberian hygromide, and the conclusion that Helix semipicta Hidalgo, 1870 is a junior synonym of Helix cistorum Morelet, 1845, has been made,further amplifying the known distribution of this species.
