Tugonia huanghaiensis Xu, 1987: 437  –438 & 441, fig. 1 a—Bernard et al. 1993: 107; Xu 1997: 230; Lutaenko & Xu 2008: 52, text-fig. 6 E, pl. 5, figs. A –D; Xu & Zhang, 2008: 257, fig. 815; Xu, 2008: 590.

Cryptomya (Venatomya) semistriata ( Hanley 1842)  — Huber (2010): 766.

Material examined. MBM no. 73 M-030 (Holotype) (1 articutate shell), Jiaozhou Bay, China, collected by Qi Zhong-yan, on October 30 th, 1973; MBM no. 57 M- 101 (not no. 56 M- 101 by Xu 1987) (Paratype) (1 articutate shell), in sand, Rudong, Jiangsu Province, China, collected by Ma Xiu-tong, on June 10 th, 1956.

Distribution and habitat. Recent. Jiaozhou Bay, China; Rudong, Jiangsu Province, China. Habitat unknown.

Type locality. Jiaozhou Bay, China.

Diagnosis. Length to 20 mm; shell globose; umbo prominent, situated subcentral and prosogyrate; periostracum yellowish; sculpture with fine radial ribs, somewhat stronger posteriorly; posterior area incipiently rostrate, with only commarginal lines; pallial sinus not reaching further anterior than posterior adductor scar; pallial line thin or obscure.

Remarks. Huber (2010) thought this species is the synonym of Cryptomya (Venatomya) semistriata ( Hanley 1842)  . Swennen et al. (2001) recognized Tugonia semistriata  ( Sowerby II, 1875) [sic] as a synonym of T. princeps A. Adams, 1851  . But judged from the figures by Sowerby II (1875: pl. 2, fig. 6 a, b) and Swennen et al. (2001: p. 97, fig. 209), C (V.) semistriata  has a deeper pallial sinus whereas it is diminutive in T. (T.) huanghaiensis  . In addition, the ventral margin of T. (T.) huanghaiensis  is much more convex than in C. (V.) semistriata  , and its umbo is much larger and more inflated.
