Blanfordia japonica var. simplex Pilsbry, 1902 | |
Blanfordia simplex is a species of land snail that has an operculum, a terrestrial gastropod mollusk in the family Pomatiopsidae.[3]
Henry Augustus Pilsbry described it as Blanfordia japonica var. simplex in 1902.[1] He has elevated this taxon to specific level in 1903.[4]
Distribution
[edit]This species is endemic to Japan.[3] It occurs widely along the Sea of Japan.[3] The type locality is Nishigo, Uzen Province, Honshu.[1]
It is a Near Threatened species.[5]
Description
[edit]Blanfordia simplex has a shell with 4.1-5.1 whorls.[2] Pilsbry (1902)[1] described the first whorl to be more or less worn.[1] The color of the shell is yellowish-olivaceous.[1] It has the lip hardly visible, only a mere trifle expanded.[1]
The width of the shell is 3.7-4.2 mm.[2] The height of the shell is 5.9-6.9 mm.[2]
