Genus Ampullataria

Shell is ellipsoid, circular in cross-section, with a cylindrical neck, covered by oval overlapping scales which appear polygonal. Neck scales are irregular at aperture. Aperture is circular, terminal. Ecology: moss. Type species: Ampullataria rotunda van Oye, 1956

Genus Deharvengia

Shell is transparent, oval or ovoid in the broad view, circular to narrow elliptical in the cross-section. Aperture elliptic or narrow elliptic, the ventral side is cut at about 6/7 of the length of the entire shell and is surrounded by a thin organic lip. On the dorsal side the shell forms a small cap over the aperture, sometimes with a narrow organic lip along the edge. Shell is covered by elongate-elliptic idiosomes. Transparent clavate spines may be present on each side of the shell (Bobrov et al., 2012). Ecology: freshwater, soils. Type species: Deharvengia papuensis Bonnet, 1979

Genus Euglyphidion

Shell is ovoid, circular in cross-section, sides taper. Aperture is terminal, circular or broadly ovoid. Shell is covered by siliceous two types of plates which do not overlap, distributed chaotically. Ecology: soils. Monospecific. Type species: Euglyphidion enigmaticum Bonnet, 1960

Genus Heteroglypha

Shell is wedge-shaped, fundus is rounded, sides sub-parallel, anterior end only slighlty smaller than fundus. In lateral view, shell is tapered almost to point at apertural end. Aperture is terminal, slit-like or slightly arched, located at right angle to the broad diameter, with clear organic rim. Scales are elliptical, arranged as in Euglypha. Ecology: freshwater. Type species: Heteroglypha delicatula Thomas et Gauthier-Lièvre, 1959

Genus Matsakision

Shell is transparent, long ovoid, slightly compressed, perpendicularly truncated near the aperture area. Shell is covered by elliptic plates, not overlapping, although sometimes may be connected, located on light yellow hyaline cement. Aperture is terminal, oval, surrounded by small organic collar, hardly visible. Pseudopodia are not reported. Ecology: terrestrial mosses. Type species: Matsakision cassagnaui Bonnet, 1967

Genus Pareuglypha

Shell is ovoid, tapered toward aperture, yellowish; fundus with scaly spine of variable length. Shell is covered by small, circular or ovoid scales, slightly overlapping, randomly distributed. Aperture is terminal, circular. Ecology: freshwater. Type species: Pareuglypha reticulata Penard, 1902

Genus Pileolus

Shell is acrostome, covered by two types of idiosomes. Large elongate idiosomes are thickened in the middle that gives tuberculated view to the shell. Small elongate idiosomes fill the gaps between the larger ones. Aperture is circular, with a collar turned up and outside, surrounded by small elongated plates with a single tooth. Monospecific. Ecology: soil. Type species: Pileolus tuberosus Coûteaux et Chardez, 1981

Genus Tracheleuglypha

Shell is ovoid, cross-section is circular, covered by large, circular overlapping idiosomes; colourless, transparent. Aperture is terminal, circular, sometimes may be surrounded by a small denticulate collar made of the organic material of the shell. Nucleus is ovular. Ecology: freshwater, moss and soil. Type species: Tracheleuglypha dentata Deflandre, 1938
