Etymology

The specific name vanbruggeni is named in honor of Dr. Adolph Cornelis van Bruggen, well-known malacologist, on the occasion of his 80th birthday and in recognition of his work on the malacofauna of Indonesia.^[1]

Distribution

The type locality is Indonesia, Central Sulawesi, Pulau [Island] Peleng, Gunung [Mount] Tatarandang, near village at foot of the mountain in low vegetation.^[1] The holotype is stored in the Nationaal Natuurhistorisch Museum Naturalis.^[1]

Shell description

Shell is solid, of a light ochre color, biconcave, regularly striated with very fine axial riblets, with numerous periostracal hairs (visible in this well cleaned sample as hair pits), covering the whole surface.^[1] The spire is deeply sunken, with 3¾-4½ whorls.^[1] Whorls are rounded, first whorls very narrow, the last one very large, and embracing the preceding one, distinctly descending in front.^[1] The umbilicus is deep, and very small (about 1/20 of the width of the shell) and partly hidden by the expanded columellar side of the peristome. The aperture is crescent, a little oblique. The peristome is very thick and expanded all around and somewhat reflexed.^[1] The two ends are connected by an extremely thick callus, forming a very strong and quite sharp arcuate tooth on the body of the penultimate whorl.^[1]

The width of the shell is 18.2-24.6 mm.^[1] The height of the shell is 10.7-14.0 mm.^[1] The width of the holotype is 21.7 mm.^[1] The height of the holotype is 13.0 mm.^[1]

So far, this most remarkable species can not be confused with any other Chloritis species because of its peculiar appearance; so far it is the only species with such a strong and sharp arcuate tooth.^[1]
