The distinctive shape and ambital band of enlarged tubercles makes this genus instanty recognizable. It differs from Echinocorys in apical disc structure, position of periproct and tuberculation. One species of Galeola with a pointed and projecting anal rostrum approaches Jeronia in shape, but Galeola has four gonopores, and no enlarged ambital tuberculation.
