Vesperopsis reticulata
Vesperopsis reticulata (Wan Chuanbiao and Zhang Ying, 1990, p.11–12, pl.3, figs.2,4,6) He Chengquan et al., 2009, p.308. 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.2; Mao Shaozhi et al., 1999, pl.4, fig.9.
Age: Early Cretaceous.
Emended description (Mao Shaozhi et al., 1999):
Contrangularia reticulata Wan & Zhang 1990, emend. Nov. (Pl. IV, Fig. 9)
Contranularia reticulate Wan & Zhang 1990. P. 11-12, Pl. IIII, Figs. 2, 4, 6.
Emended description: A species of Contrangularia which has commonly a slightly larger antapical horn than that right postcinular horn and reticulate ornaments on wall surface. Cingulum indicated faintly by low ridges. Sulcus commonly not indicated. Archeopyle suture weakly angular.
Comparison: The species differs from N. granulate in having reticulate ornamentation on wall surface.
Location and horizon: Xin-Balhu Zhouqi of the Hailaer Basin, the second Member of the Damoguehe Formation, Hauterivian
