A new species of terrestrial gastropod belonging to the family Diplommatinidae Pfeiffer, 1856, is described from a single limestone karst from Peninsular Malaysia. Opisthostoma gittenbergeri spec. nov., differs from its congeners by having its protoconch and top whorls together markedly oblique in relation to the body whorls.
