Diplommatina (Sinica) subcylindrica Möllendorff, 1882 Diplommatina subcylindrica Möllendorff, 1882: 349–350. – Yen, 1939: 31, pl. 2, fig. 42. Diplommatina (Sinica) subcylindrica – Kobelt & Möllendorff, 1898: 142; Kobelt, 1902: 473; Zilch, 1953: 36. Type material. Lectotype SMF 39661 (Figs 7 H, 13 H), designated by Yen (1939). Type locality. Yang-hu, Fudshien. The current name of the locality cannot be confirmed. Brief description. Shell dextral, with about 7 whorls. Protoconch smooth. Penultimate whorl slightly wider than body whorl. Constriction at middle of parietal wall. Teleoconch with weak, dense, radial ribs. Dorsal fold absent. Umbilicus unknown. Double lip present. Columellar tooth weak. One strong horizontal palatalis just above columella. One short vertical palatalis. Remarks. A single type specimen is known to exist. It has been referred to as the holotype and was figured by Yen (1939). However, the original description does not contain a type designation nor does it specify the number of specimens on which it is based. Therefore, Yen’s (1939) reference to the holotype is herein considered to constitute a lectotype designation in accordance with Art. 74.6 of the Code (ICZN 1999). Kobelt and Möllendorff (1898) assigned this species to the subgenus Sinica.
