Blanfordia simplex is a species of land snail that has an operculum, a terrestrial gastropod mollusk in the family Pomatiopsidae. [3]

Contents

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]
