Treatment

Diplommatina longxianensis Chen, Liu, Xu & Yan, 1994: 44, fig. 1.

Type material.

Holotype IZCAS TM 010064 (Figs 6 C View Figure 6 , 12 N View Figure 12 ) , 29 paratypes IZCASTM 010065-010093 .

Type locality.

Longxian County, Shaanxi Province.

Brief description.

Shell dextral, with about 6.5 whorls. Protoconch smooth. Penultimate whorl slightly expanded; body whorl nearly as wide. Teleoconch with thin, dense, radial ribs; ca. 7 ribs per 0.5 mm on penultimate whorl, ca. 6 ribs per 0.5 mm on body whorl. No double lip. Columellar tooth present. No horizontal palatalis nor vertical palatalis visible.

Remarks.

The original literature mentions 26 paratypes ( Chen et al. 1994). Nonetheless, 29 specimens were deposited together that correspond to the collection’s locality and time mentioned in literature, indicating that the correct number of paratypes should be 29 ( ICZN Art 72.4. 1).
