Notharinia
- Notharinia attenuata
The spire is cylindrical, often somewhat attenuated towards the base. The aperture is approximately circular and attached to the preceding whorl, with a simple peristome. Low, thin radial ribs are densely spaced, and spiral striation is absent. Shells are recorded from soil deposits in somewhat disturbed to degraded semi-deciduous woodland on limestone bedrock. Shells are known from the Banteay Meas and Kampong Trach areas of Kampot Province, Cambodia, and Kien Luong District, Kien Giang Province, Vietnam.
- Notharinia brevior
The spire is shortly cylindrical to somewhat ovoid-cylindrical. The aperture is approximately circular, with a somewhat thickened and reflected peristome. Low, thin radial ribs are densely spaced, and spiral striation is absent. Shells are recorded from soil deposits in degraded secondary woodland on limestone bedrock. Shells are known from the Kampot and Banteay Meas areas of Kampot Province, Cambodia, and the Ha Tien area of Kien Giang Province, Vietnam.
- Notharinia constricta
The spire is shortly cylindrical, rarely slightly ellipsoid. The peristome is double, with the inner rim projecting slightly to distinctly beyond the outer rim. The radial ribs are low and thin, and spiral striation is absent. Shells are recorded from soil deposits in moderately disturbed to degraded partly deciduous woodland on limestone bedrock. Shells are known from Phnom Chhngauk and Phnom La’Ang in the Kampot area, Kampot Province, Cambodia.
- Notharinia crassilabris
The spire is cylindrical, not or hardly attenuated towards the base. The peristome is double, with the inner rim projecting distinctly beyond the outer rim. The radial ribs are rather high and thick, and spiral striation is absent. Shells are recorded from soil deposits in disturbed to degraded secondary woodland on limestone bedrock. Shells are known from Kampot Province, Cambodia, and the Ha Tien area of Kien Giang Province, Vietnam.
- Notharinia lyostoma
The spire is cylindrical, usually slightly attenuated towards the base. The aperture is approximately circular and free, with its parietal edge separated from the preceding whorl. The radial ribs are low, thin and densely spaced, and spiral striation is absent. Shells are recorded from soil deposits in degraded woodland on limestone bedrock. Shells are known from Phnom Kampong Trach, Kampot Province, Cambodia.
- Notharinia ongensis
The spire is shortly cylindrical and broadly rounded towards the apex. The aperture is approximately circular, with a simple peristome. A slight to moderately distinct constriction occurs about half a whorl before the aperture. Shells are recorded from soil deposits in disturbed to degraded woodland on limestone bedrock. The shell type specimens are recorded from Nui Ong, Kien Luong District, Kien Giang Province, Vietnam.
- Notharinia soluta
The spire is cylindrical and does not narrow towards the base. The aperture is free and approximately circular, often slightly angular at the basal corner. The radial ribs are low and thin, and spiral striation is absent. Shells are recorded from soil deposits in degraded woodland on limestone bedrock. Shells are known from the limestone hills in the Banteay Meas area, Kampot Province, Cambodia.
- Notharinia stenobasis
The spire is cylindrical, slightly to distinctly attenuated towards the base. The peristome is double, with the inner rim projecting slightly beyond the outer rim. The radial ribs are low and thin, curving towards the suture on the body whorl; spiral striation is absent. Shells are recorded from soil deposits in moderately disturbed semi-deciduous woodland on limestone bedrock. Shells are recorded from the southeastern end of Phnom La’Ang, Kampot Province, Cambodia.
- Notharinia subduplex
The spire is cylindrical, not or hardly attenuated towards the base. The peristome is double, sometimes indistinctly so, with the inner rim projecting slightly beyond the outer rim. The radial ribs are low, thin and densely spaced, and spiral striation is absent. Shells are recorded from soil deposits in disturbed semi-deciduous woodland and shrubby vegetation on limestone bedrock. Shells are recorded from the northern and southern hill remnants of Nui Khoe La, Kien Luong District, Kien Giang Province, Vietnam.
- Notharinia whitteni
The spire is cylindrical, not or hardly attenuated towards the base. The aperture is approximately circular to obtusely rectangular, with a double peristome. The radial ribs are rather high, thick and densely spaced, and spiral striation is absent. Shells are recorded from soil deposits in disturbed semi-deciduous woodland and shrubby vegetation on limestone bedrock. Shells are recorded from the northern and southern hill remnants of Nui Khoe La, Kien Luong District, Kien Giang Province, Vietnam.
