Material examined. Pyeongchang-gun (37°41′44.7″N, 128°45′49.6″E), Korea; collected by CH Lee and MO Song on 4 October 2021 .

Deposition. NIBRIV0000895442.

World distribution. Germany, Portugal and Korea.

Diagnosis. Rostral lamella bilobed, slightly wider than rostrum end; each lobe round. Rostrum short. Pharyngeal tube as long as trophi length. Corona much narrower than cingulum. Upper lip higher than trochal discs, round triangle-shaped, and with wavy lateral margins. Pedicel high. Foot very short and with four pseudosgements; about 1/12 of total length in creeping. Spurs conical, short and with narrow interspace.

Remarks. The morphology of H. stenostephana agrees well with that in the original description except that the rostral lamella is bilobed in the Korean specimens, while that is without median notch in the original description.
