Diplommatina xiazayuensis Chen & Guo, 2001: 166–169 View in CoL , figs 4, 5.

Type locality.

Zayu, Xizang Autonomous Region.

Type material.

Holotype IZCAS TM 1010000 (Figs 7 J View Figure 7 , 13 J View Figure 13 ) , 53 paratypes IZCAS TM 010001-010053 .

Brief description.

Shell dextral, with about 6.5 whorls. Protoconch smooth. Penultimate whorl slightly expanded, body whorls nearly as wide. Teleoconch with thin, widely spaced, radial ribs; with ca. 8 ribs per 0.5 mm on penultimate whorl and ca. 7 ribs per 0.5 mm on body whorls. Double lip present. Columellar tooth present. No horizontal palatalis nor vertical palatalis visible.

Remarks.

The holotype is broken; therefore, the paratype IZCAS TM 010045 (Fig. 7 K View Figure 7 ) was also photographed. In the original literature, there are a total of 37 paratypes. However, 53 specimens match the collection locality and time in the literature and were deposited together, suggesting that the paratypes should be 53. ( ICZN Art 72.4. 1).
