''Halongella schlumbergeri'' is a species of air-breathing
The reproductive system was described by Páll-Gergely et al. in 2015. Embryos were recorded to be present in the uterus. There were recorded flat, thin, with no particular shape calcareous granules on the internal surface of penis.

Description
The most important shell characters for identification of ''Halongella schlumbergeri'' include: the shell is robust; callus and aperture shape (including the formation of the fold). The size of the shell is medium to very large. The shell is thick, almost smooth or with very fine periostracal ribs. The width of the shell is 16.1–28.1 mm. The height of the shell is 7.0–13.1 mm. The apertural lip is well-developed. The apertural fold is long, more or less equally long in its total length, connected to the callus. Two oblique apertural views of the same shell: Parietal wall is with missing or short anterior lamella (always distant from the upper plica) and well-developed posterior lamella. The species is very variable in terms of shell size and the formation of plicae and lamellae on the parietal wall. Palatal plicae are depressed and Z-shaped. Theradula
The radula (, ; plural radulae or radulas) is an anatomical structure used by molluscs for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food ...
of ''Halongella schlumbergeri'' has 10 lateral teeth and 14 marginal teeth. The size of the central tooth is smaller than the ectocone of the first lateral. The shape of the first lateral is oval. Marginal teeth are bicuspid or tricuspid with blunt inner cusp and shallow incision between the inner two cusps.
The reproductive system was described by Páll-Gergely et al. in 2015. Embryos were recorded to be present in the uterus. There were recorded flat, thin, with no particular shape calcareous granules on the internal surface of penis.

'' resemble ''Halongella schlumbergeri'' in terms of general, but the inner lamellae are entirely different. Most ''Halongella schlumbergeri'' shells lack the anterior lamella. ''Gudeodiscus dautzenbergi'' and ''Gudeodiscus villedaryi'' have strong, well-developed anterior lamella with an anteriorly elongated lower “leg”. It is possible to distinguish ''Halongella schlumbergeri'' from the other two species without breaking the shell, on the basis of the long apertural fold reaching the callus, which is short in ''Gudeodiscus dautzenbergi'' and ''Gudeodiscus villedaryi'', and has an elevated “knob” part in some distance from the callus.
Ecology
It is a ground-dwelling species as all other plectopylid snails in Vietnam.References
