Rhagada convicta, copyright G. & Ph. Poppe.

Belongs within: Helicoidei.

The Hadrinae are a group of land snails found in Australia and southeast Asia united by molecular analysis. Members of this clade either lack a head wart or have the head wart (positioned between and just behind the ommatophores) exposed and not eversible (Solem 1997).
