Vesperopsis granulata
Vesperopsis granulata (Wan Chuanbiao and Zhang Ying, 1990, p.12, pl.3, figs.7–9) He Chengquan et al., 2009, p.307. Emendation: Mao Shaozhi et al., 1999, p.155.
Originally Contrangularia, subsequently (and now) Vesperopsis. He Chengquan et al., (2009, p.307) incorrectly considered the new combination to be a "stat. nov." as well as a "comb nov".
Holotype: Wan Chuanbiao and Zhang Ying, 1990, pl.3, fig.8.
Age: Early Cretaceous.
Emended description (Mao Shaozhi et al., 1999):
Contranularia granulate (Wan & Zhang 1990) emend. Nov. (Pl. IV, Fig. 4; Pl. V, Fig. 5)
Contrangularia granulate Wan & Zhang 1990, p. 12, Pl. III, Fig. 8.
Emended description: A species of Contranularia that has usually a longer and narrow left precingular horn upwards, a short and broad right precingular horn downwards and granulate ornamentation on wall surface.
Comparison. The species differs from Contrangularia reticulate in having granulate ornamentation on wall surface and in being slightly smaller than the latter species.
Location and horizon: Xin-Balhu Zhouqi of the Hailaer Basin, the second Member of the Damoguehe Formation, Hauterivian.
