Canningia xinjiangensis
Canningia xinjiangensis, Chen et al., 1988, nom. subst. pro Hashenia reticulata Yu Jingxian and Zhang Wangping, 1980
The transfer of Hashenia reticulata to Canningia, would result in the name being a junior homonym of Canningia reticulata Cookson and Eisenack, 1960. Accordingly, Chen et al., 1988, proposed Canningia xinjiangensis as a substitute name for the species erected by Yu Jingxian and Zhang Wangping, 1980.
Holotype: Yu Jingxian and Zhang Wangping, 1980, pl.2, fig.1.
Age: Turonian-Maastrichtian
