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

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

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]

The shell of Blanfordia simplex is shorter and broader than that of Blanfordia bensoni.[1]

Ecology

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

This species lives on coastal dunes and in littoral forests.[3]
