Information from the abstract

9Diplommatina affinisTheobald, 1870 Fig. 15 A Diplommatina affinis Theobald, 1870: 398. Type locality: Shan States. Pfeiffer 1875: 70. Theobald 1876: 41. Godwin-Austen 1884: pl. 49, fig. 3. Godwin-Austen 1886: 181, 182. Gude 1921: 302. Diplommatina (Eudiplommatina) affinis — Kobelt and Möllendorff 1898: 135. Diplommatina (Diplommatina) affinis — Kobelt 1902: 424. Type material examined. Unknown or probably lost. Diagnosis. Shell dextral, ovate-turreted. Whorls 7, increasing regularly; ribs weak, slightly prominent on last whorl. Aperture ovate; columellar straight, columellaris small. Peristome double; outer peristome slightly expanded. Distribution. The species was known from Shan State (Theobald 1870) and was subsequently recorded from Modi Taung in the Arakan Hills, Rakhine State, Myanmar, by Godwin-Austen (1886). Remarks. This is one of four diplommatinid species described by Theobald (1870) for which the type series could not be located in either the NHM, London, nor the NMW, Cardiff (T. White, B. Rowson, and J. Gallichan, pers. comm.). As the type specimens could not be examined, the diagnosis provided here is based on the original description and the illustration by Godwin-Austen (1884: pl. 49, fig. 3).
