Isabelidinium microverrusum

"?microverrusum" (Yu Jingxian and Zhang Wangping, 1980, p.109, pl.3, figs.1–2) Lentin and Williams, 1985, p.201.  Holotype: Yu Jingxian and Zhang Wangping, 1980, pl.3, fig.2.  NOW Alterbidinium.  Originally Deflandrea, subsequently Isabelidinium?, thirdly (and now) Alterbidinium.  Questionable assignment: Lentin and Williams (1985, p.201).  Yu Jingxian and Zhang Wangping (1980, p.109) spelled the epithet as "microverrusa", but as "microverrucosa" in their plate caption.  Previous editions of the "Lentin and Williams Index" and DINOFLAJ2 have cited the epithet as "microverrucosa / microverrucosum", but He Chengquan et al. (2009, p.416) used "microverrusum", which we follow here.  Age: Campanian–early Maastrichtian.
