Shell dextral, with about 6–6.5 whorls. Protoconch smooth. Penultimate whorl slightly expanded; body whorl nearly equal in width. Constriction at middle of parietal wall. No spiral striation visible.

Remarks.

The lectotype is designated herein in accordance with Art. 74 of the Code ( ICZN 1999) for the stabilisation of the name. Johnson listed ‘ paratypes’ housed in the MCZ. Diplommatina minuscula Chen & Zhang, 1998 is a junior homonym and, therefore, the name is permanently invalid. A replacement name Diplommatina yunnanensis is proposed below ( ICZN Art 34.2).
