Hypselostomatidae is a family of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the superfamily Pupilloidea.[1]
The shell of a typical hypselostomatid ranges from conical or conical-ovoid to depressed-conical. However, the body whorl frequently becomes detached from the penultimate whorl (Hoekstra and Schilthuizen 2011; Chen et al. 2022). This separation—known as a solute or uncoiled condition—drastically alters the overall shell profile, often resulting in a trumpet-like or distorted appearance.[2][3][4]

Taxonomy
The Hypselostomatidae were originally established as a subfamily of Chondrinidae (Zilch 1959). In that same work, Zilch erected the subfamily Aulacospirinae, which was later synonymized by Schileyko (1998). Systematic placement has since remained a subject of debate: while Bouchet et al. (2017) treated the group as a subfamily of Gastrocoptidae, other authors have classified these representatives under Vertiginidae (Panha 1998; Tanmuangpak and Dumrongrojwattana 2022) or Pupillidae (Burch and Panha 2002). More recently, several authors have advocated for full family status as the Hypselostomatidae (Gojšina et al. 2022; Páll-Gergely 2023a, b).[4]
