Holospira is a genus of air-breathing, land snails, terrestrial pulmonate gastropod molluscs in the family Urocoptidae.
Holospira is the type genus of the subfamily 'Holospirinae Pilsbry, 1946'.
Holos (ὅλος) from Ancient Greek means "‘whole’" or "‘entire’" and spira (spīra) from Latin means spire.
The shell is small, cylindric, terminating above in a conic spire, retaining all the whorls, rimate or perforate. The shell has 11-21 whorls, which are closely coiled. The first 1½ of whorls are smooth. The rest of whorls are smooth, striate or ribbed. The suture is superficial. Body whorl is more or less built forward.
The aperture is small, obliquely pear-shaped, rounded or oval. The peristome is expanded or reflected, continuous and usually free throughout.
The columella (internal column) is hollow, variously sculptured or smooth.
The foot is small, narrow for its length.
