The genus Sculptaria is the only genus of the snails - family Sculptariidae from the suborder of the land snails (Stylommatophora). Genus and family include only about 20 species and subspecies that are native to southwest Africa.
features
The housings are flattened, lens-shaped or disc-shaped and heavily sculpted. Up to about six turns are formed, the periphery is keeled. The shell is relatively thick. The mouth is oblique to the winding axis and heavily modified. It drops off sharply from the winding plane and is "free" at the extreme end, i.e. H. without contact with the previous turn. There is one parietal lamella and two or three palatal plicae. The edges are bent and widened. In the hermaphroditic genital apparatus, the penis is moderately long with a subapical image sac. The epiphallus and flagellum are very short. The spermatic duct does not lie against the penis. The vagina, on the other hand, has no appendix. The stem of the sperm library is relatively long and only slightly broadened at the base. It is not associated with the spermoviduct.
Occurrence, way of life and distribution
The species of the Sculptariidae family or the Sculptaria genus are native to south-western Africa, and there has been evidence so far in southern Angola, Namibia and South Africa. They live there in dry and hot areas with sparse vegetation.
Systematics
The family is placed in the superfamily Acavoidea by Schileyko (2005) . Bouchet & Rocroi (2005), however, place them in the superfamily Plectopyloidea. So far around 20 species and subspecies have been described, the status of which is often not entirely certain. A modern processing of the genus is not yet available.
