The type series of the Iberian endemic hygromiid Helicella mariae was studied conchologically, with the purpose of clarifying its taxonomic status. This study compares protoconch and teleoconch microsculpture and hairs of Helicella mariae and the most similar hygromiid species Microxeromagna lowei and Xerotricha conspurcata. The study of dried specimens of Helicella mariae found inside some shells was inconclusive because of the specimens’ immaturity. Based on the conchological characters examined and on distributional data, Helicella mariae must be considered a junior synonym of Xerotricha conspurcata. The distribution map in the Iberian Peninsula for this species is shown.
