Chloritis togianensis

The type locality is Togian Island, principle island of the Togian Archipelago, lying in the Tomini Bay, Central Sulawesi, Indonesia.[1]

The shell is solid, unicolored light ochre, biconcave, irregularly striated according to some growth lines, with numerous hair pits covering the whole surface.[1] The spire is deeply sunken.[1] The shell has 3¾-4½ whorls.[1] Whorls are rounded, first whorls very narrow, the last one very large, and partly embracing the preceding one, distinctly descending in front.[1] The umbilicus is deep, and about 1/8 of the width of the shell.[1] The aperture is crescent, a little oblique, peristome thick and expanded all around and is somewhat reflexed; both ends connected by a quite thin callus.[1] The width of the shell is 17.1-19.9 mm.[1] The height of the shell is 9.5-11.7 mm.[1]

Apical, apertural and umbilical view of the shell of the holotype of Chloritis togianensis. The width of the shell is 18.4 mm.[1] The height of the shell is 9.8 mm.[1]

The species may be compared to only a few species showing the same kind of rotating of the penultimate whorl especially, and possessing simultaneously a sunken shell shape.[1] Chloritis bifoveata (Benson, 1856) from West Malaysia is smaller (width is 15 mm), and the spire is much deeper; Chloritis unguiculastra (Martens, 1867) is somewhat larger (width is 22 mm), is smooth without hair or hair pits, and is more regularly coiled; Chloritis ungulina (Linnaeus, 1758) is much larger (width is 44 mm) is smooth without hair or hair pits, has a groove at the base of the penultimate whorl near the umbilicus and the whorls are more flattened, not rounded.[1]
