The native distribution of Bulimulus tenuissimus includes:

  • Brazil – widespread in Brazil[2]

The non-indigenous distribution includes:

The shell is perforate, ovate-conic, very thin, pellucid, scarcely shining, obsoletely and closely decussated by growth striae and delicate spiral lines.[5] The shell is pale corneous in color, sometimes fulvous.[5] The spire is conoid.[5] The apex is rather acute.[5] The suture is simple.[5] The shell has six whorls that are slightly convex, increasing with moderate rapidity.[5] The last whorl is convex, not descending in front, somewhat attenuated at base.[5] The columella is suboblique, sometimes nearly vertical.[5]

The aperture is oval, colored like the exterior, onehalf the shell’s length.[5] The peristome is simple, unexpanded, acute.[5] The right margin is regularly arcuate.[5] The columellar margin is reflexed above, nearly covering the perforation.[5]

The width of the shell is 9 mm. The height of the shell is 17 mm.[5]
