Bostryx chusgonensis is a species of tropical air-breathing land snail, a pulmonate gastropod mollusk in the family Bulimulidae.

[2] The Bostryx chusgonensis sipas is separated by mountain ranges from the nominate subspecies.

[2] It is characterized by its small size (13 mm), spindle-shape, whitish colour and smooth surface.

[2] The height of the shell is up to 13.4 mm, three times as long as wide, rimate, spindle-shaped, with slightly convex sides, rather thin.

Colour is uniformly greyish-whitish or with axial streaks of light to dark-brown, the upper whorls somewhat darker; a dark band around the rimate umbilicus.
