Beschreibung:
<jats:p>The genus <jats:italic>Habeastrum</jats:italic> Simone, 2019 was recently described based on empty shells, counting with two troglobite species. Conchological features allowed a preliminary classification in the caenogastropod family Diplommatinidae, but this family allocation was left open to future studies. Herein, we present a detailed anatomical study of newly acquired specimens, confirming the classification in Diplommatinidae. These new specimens, from Minas Gerais state, SE Brazil, belong to a new troglobite species described herein, <jats:italic>Habeastrum strangei</jats:italic><jats:bold>sp. nov.</jats:bold> The present records extend the genus distribution ca. 1,100 km east-northeast.</jats:p>
