Halongella schlumbergeri

clade Euthyneuraclade Panpulmonata clade Eupulmonata clade Stylommatophora Helix (Plectopylis) Schlumbergeri Morlet, 1886 Gudeodiscus schlumbergeri (Morlet, 1886) Plectopylis jovia Mabille, 1887[2] Gudeodiscus jovius (Mabille, 1887) Plectopylis (Endoplon) hirsuta Möllendorff, 1901[3] Gudeodiscus hirsutus (Möllendorff, 1901) Plectopylis pilsbryana Gude, 1901[4] Gudeodiscus pilsbryana (Gude, 1901) Halongella schlumbergeri is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Plectopylidae.

[5] The distribution of Halongella schlumbergeri includes Hạ Long Bay area in Haiphong municipality and Quảng Ninh Province, Vietnam.

[5] The species is very variable in terms of shell size and the formation of plicae and lamellae on the parietal wall.

[5] There were recorded flat, thin, with no particular shape calcareous granules on the internal surface of penis.

[5] 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.
