Diplommatina yunnanensis Zhang, Xie & Köhler nom. nov. Diplommatina minuscula Chen & Zhang, 1998: Vol 23, No 4, 347. fig. 2 Diplommatina yunnanensis Zhang, Xie & Köhler, nom. nov. Type material. Holotype IZCAS TM 009566 (Figs 8 A, 13 L), 24 paratypes IZCAS TM 009547-009570, one paratype IZCAS 156036, one paratype IZCAS 155985, 138 paratypes IZCAS TM 048307-048444. Type locality. Mengla County, Yunnan Brief description. Shell dextral, with about 7.5 whorls. Protoconch smooth. Penultimate whorl slightly expanded, body whorls nearly as wide. Teleoconch with strong, widely spaced, radial ribs; with ca. 6 ribs per 0.5 mm on penultimate whorl and ca. 5 ribs per 0.5 mm on body whorls. Double lip present. Columellar tooth absent. No horizontal palatalis nor vertical palatalis visible. Remarks. The original spelling of the species name “ minusculus ” is incorrect. The name is an adjective and needs to be in the same gender as the genus name (ICZN Art 31.2). The correct name is ‘ minuscula ”, which renders this taxon a junior homonym of D. minuscula Heude, 1890. Here, D. yunnanensis is introduced as a replacement name in accordance with Art 34.2 of the Code (ICZN 1999). The type material has been deposited with the NCMZ (Chen and Zhang 1998). The type locality is Xishaungbanna in Yunnan Province. In the original literature, there are a total of 138 paratypes. However, 164 specimens were deposited together and the collection locality and time in the literature were matched, suggesting that the paratypes should total 164 (ICZN Art 72.4. 1).
