Original Description of Dasyostoma by Stewart, 1927, p. 368:
" ´Rimella´ rugostoma Johnson, from Jackson, Miss. (Upper Eocene) is also, I believe, near Ectinochilus, but it, too, is without varices. Its crenulated aperture is so unique that it seems best to recognize it as a distinct subgenus under the new name Dasyostoma."
Type species of Dasyostoma is Rimella rugostoma Johnson, 1899 by original designation.
