and spring. This taxon’s main features are as follows: remarkably large cells and scales; a strongly hooded V-rib; a considerably various shield ornamentation; and delicate, regularly spaced, transverse ribs occasionally connected by cross ribs. The posterior flange with stout struts is more widely spaced than the ribs of the shield. Its dome is marked with ribs or is in a smooth shape. This species is distributed across the northern temperate region. It was not recorded in Korea previously.
