Abstract:The study reported a new species of the genus Sinoennea Kobelt, 1904 from China: Sinoennea longtangshanensis sp. nov. The material was collected by the authors in Longtangshan Town, Linan City, Qingliangfeng Nature Reserve, Zhejiang Province, China. Shell of Sinoennea longtangshanensis is small (height 4.40 mm, diameter 2.40 mm), thin, with 6.5 whorls. The last and penultimate whorls are translucence. Aperture has 4 barriers. The type specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences, China.
Sinoennea longtangshanensis sp. nov. (Plate Ⅰ: 1~5)
Holotype. Height 4.40 mm, diameter 2.40 mm, height of aperture 1.30 mm, diameter of aperture 1.21 mm, height of spire 2.80 mm, collected by authors from Longtangshan Town, Linan City, Qingliangfeng Nature Reserve (30°01'N, 118°80'E), Zhejiang Province, China, 26 June 2013.
Paratypes. 26 adult specimens. Height 4.10~4.50 mm(4.32 mm±0.18 mm), diameter 2.35~2.45 mm (2.38 mm±0.15 mm), height of aperture 1.25~1.35 mm (1.31 mm±0.11 mm), diameter of aperture 1.20~1.30 mm (1.24 mm±0.09 mm), height of spire 2.59~2.88 mm (2.74 mm±0.14 mm), collecting data same as holotype.
Description: Shell is small, thin, lustrous, cylindrical conic and with a rather truncated apex. The last and penultimate whorls are translucence. Whorls are 6.5, moderately convex with high spire. Apex is blunt, short and ovate. Sutures are deep. Shells are white or light yellow in color, with regularly spaced 120~130 pronounced some strong curve vertically rib-striae (23~26 ribs on the last whorl), but the embryonic and second whorls are smooth, without rib-stria. Aperture is small, elliptical shaped. Peristome margin is thick, expanded and reflexed; and the angular region is slightly curved backward. Apertural barriers are 4: one strong flake-shaped parietal tooth is connected with parietal callus, and the end of parietal tooth is somewhat bilobed; two connected nipple-formed palatal teeth are nearly equal in size, one is situated at the edge of the peristome, and the other is a bit deeper within the aperture; on the columellar lip, there is one large nipple-shaped columellar tooth even deeper within the aperture. Umbilicus is small, narrow and chink-shaped.
Habitat: This new species was found in limestone areas of mountainous regions, in dark, moist habitats with bryophyte and lichen, on the surface of limestone or in chink of rock.
Discussion: The new species is similar with Sinoennea fuzhouensis Zhou & Chen, 2006 and Sinoennea pupoidea Zhou & Zhang, 2009. Sinoennea fuzhouensis differs from the new species by the following shell characters: Shell of Sinoennea fuzhouensis is thicker and bigger (height 5.17 mm, diameter 2.57 mm), with 7.5 whorls. Aperture is ear-shaped, with 3 teeth, columellar tooth wanting. Aperture of Sinoennea pupoidea also has four barriers, but it differs obviously from the new species. Shell of Sinoennea pupoidea is smaller (height 2.94 mm, diameter 1.68 mm), thick, not translucence, pupa-shaped, with 5.5 whorls.
