Serina cathaica— Gredler, 1898b: 106. Yen, 1939: 87, pl. 8, fig. 20. Yen, 1942: 255. Chen, Zhou, Luo & Zhang, 2003: 442. Buliminus (Serina) cathaicus— Möllendorff, 1901: 360, pl.16, figs. 11–14. Kobelt, 1902: 862, pl. 123, figs. 11–14.
Type locality. Between Yulinkuan and Wenxian (Gansu) .
Material examined. ZI RAS (not numbered): 1 juv. NHM-1902.5.13.19 Reg.: 1 fms (measurements: wh 9.000, h 10.6 mm, w 2.8 mm, aph 3.0 mm, aw 2.4 mm); Gansu. SMF-42046: 4 fms.
Distribution. S Gansu.
Diagnosis. Shell with the most swollen part occurred at penultimate whorl. Whorls with a narrow, defined zone below the suture. Last whorl ascending immediately near aperture; straight at periphery; completely attached to body whorl. Aperture not duplicate.
Shell. Turrited, or ovate-turriform; dextral; with apex not abruptly pointed; with the most swollen part occurred at penultimate whorl; height 9.7–10.4–11.4, diameter major 2.8–3.0–3.3, ratio of height /diameter major 3.30–3.45–3.68. Growth lines fine and clear. Whorls 8 1/8–8 3/8–8 5/8, convex; with a narrow, defined zone below the suture. Embryonic shell 1 1/4–1 1/2+–2 whorls. Postnuclear whorls smooth. Last whorl ascending immediately near aperture; straight at periphery; with a rugate region with abapertural crowded and/or thickened growthline-like folds. Aperture in a plane and straight; ovate; almost vertical; completely attached to body whorl; height 2.7–2.9–3.4, width 2.0–2.4–2.8, ratio of shell height /apertural height 3.37–3.59–3.83. Aperture not duplicate. Peristome and parietal callus almost completely fusing except for a channel at upper insertion of peristome.
Reflexed part of peristome straight and not curved backward. Abapertural peripheral depression on body whorl spirally extending for ca. 1 whorl. Columellar margin reflexed. Columella arched. Umbilicus narrowly open. Shell uniformly chestnut, with aperture identically or brightly coloured. Measured specimens: SMF-42046, 4 shells.
FIGURE 1. Distribution of Serina species. S. soluta inflata Yen, 1939 is also indicated although synonymized in this paper. S. soluta stenochila (Möllendorff, 1901) is not mapped due to imprecise locality information.
