Auriculella uniplicata is a species of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks, belonging to the family Achatinellidae. [2]
The length of the shell attains 7 mm, its diameter 4 mm.
(Original description in French) The shell is solid and characterized by an oval-elongated shape, featuring a distinct umbilical perforation. This species is polymorphic in its coiling, appearing indifferently as either dextral or sinistral. This is a fascinating biological detail.
The spire is conic and terminates in a slightly obtuse summit, with a well-marked suture. There are six whorls, which are plano-convex in profile and finely striated in a longitudinal direction. The aperture is slightly oblique and takes a truncated-oval form.
The peristome is strongly thickened, and its margins are joined above the body whorl by a callous deposit. The parietal margin is equipped with a thin lamella, while the columellar margin remains simple, entirely lacking any kind of lamella or fold. Regarding its coloration, the shell is yellowish or light brown, accented by a transverse band of a darker shade. [3]
