Diplommatina (Sinica) paxillus subsp. hunanensis Zilch 1953

Diplommatina (Sinica) paxillus hunanensis Zilch, 1953 Diplommatina paxillus var. latecostata Gredler, 1887: 157. Diplommatina (Sinica) paxillus var. latecostata – Kobelt & Möllendorff, 1898: 141; Kobelt, 1902: 469. Diplommatina paxillus latecostata – Yen, 1939: 32, pl. 2, fig. 49. Diplommatina (Sinica) paxillus hunanensis Zilch, 1953: 34. Type material. Seven syntypes SMF 39641 (Figs 6 G, 12 R). Type locality. “ Hunan ” [Hunan Province]. Brief description. Shell dextral, with about 6 whorls. Protoconch smooth. Penultimate whorl wider than body whorl. Constriction at middle of parietal wall. Teleoconch with strong, widely spaced, radial ribs; about 3 ribs per 0.5 mm on both penultimate and body whorl. Dorsal fold absent. Umbilicus unknown. Double lip present. Columellar tooth present. One vertical palatalis. No horizontal visible. Remarks. Yen (1939) listed and figured one ‘ paratype’ in the SMF. Zilch (1953) listed seven ‘ cotypes’. Further type specimens are likely kept in the Gredler collection in the Franziskanermuseum Bozen (see Zilch (1974)). The original name is an objective junior synonym of Diplommatina latecostata Mousson, 1870 and, therefore, permanently invalid. Zilch (1953) introduced Diplommatina paxillus var. hunanensis as a replacement name.
