A conversation on Conch-L:

10/12/22  Marlo:  "Who can give us background of when Tegula fasciata (Born, 1778) became Agathistoma fasciatum (Born, 1778)?"

10/15/22  Harry Lee:  "...DeVries (2007) seems to be the first to exalt Agathistoma Olsson & Harbison, 1953 to full generic rank as ... Dornellas et al. (2021) inferred."   "The molecular genetic revelations of Dornellas et al. (2021) certainly provided convincing validation of the DeVries morphologic work."
