Euthema truncatellina is a fossil species of minute land snails with an operculum, terrestrial gastropod molluscs in the family Diplommatinidae, described from the Cretaceous Burmese amber.[1][2][3][4]
Description[]
Shell almost cylindrical, comprising 6.5 moderately convex whorls, ribbed, with weak constriction. Aperture circular. Umbilicus narrow. Periumbilical keel absent. Height of shell 1.7 mm, width of shell 0.9 mm.[1][2]
Etymology[]
The species is named after the extant genus Truncatellina (Stylommatophora), which has a similar shell, acknowledging the convergence in the different lineages of gastropods on land.[1]
