Type material.

Lectotype, HMT 234 a (Figs 6 E View Figure 6 12 P), designated herein ; two paralectotypes HMT 234 b, two paralectotypes MCZ 167032 About MCZ .

Type locality.

“ Tchen-kou, Szechwan ” [Chengkou, Chongqing City].

Brief description.

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. Teleoconch with strong, widely-spaced, radial ribs; ca. 6–8 ribs per 0.5 mm on both penultimate and body whorls. Dorsal fold absent. Umbilicus closed. Double lip present. Columellar tooth present. One short horizontal palatalis just above columella. One short vertical palatalis.

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).
