Blanfordia simplex is a species of land snail that has an operculum, a terrestrial gastropod mollusk in the family Pomatiopsidae.[4]

Henry Augustus Pilsbry described it as Blanfordia japonica var. simplex in 1902.[2] He has elevated this taxon to specific level in 1903.[5]

Distribution

This species is endemic to Japan.[4] It occurs widely along the Sea of Japan.[4] The type locality is Nishigo, Uzen Province, Honshu.[2]

It is a Near Threatened species.[1]

Description

Blanfordia simplex has a shell with 4.1-5.1 whorls.[3] Pilsbry (1902)[2] described the first whorl to be more or less worn.[2] The color of the shell is yellowish-olivaceous.[2] It has the lip hardly visible, only a mere trifle expanded.[2]

The width of the shell is 3.7-4.2 mm.[3] The height of the shell is 5.9-6.9 mm.[3]

Ecology

Habitat of terrestrial species Blanfordia simplex is on the forest floor.

This species lives on coastal dunes and in littoral forests.[4]
