Scientific name
Apogastropoda

The Apogastropoda ( old Greek ἀπό = from, of it; old Greek γαστήρ = belly, stomach; Greek πόδι = leg, foot) form a taxon in the systematics of biology (mollusks, snails). It unites the phylogenetic sister groups of the Caenogastropoda and Heterobranchia .

The taxon was made known in 1987. In the system of Ponder & Lindberg (1997) it is represented as a subclass of the subclass of Orthogastropoda . In the system of Bouchet & Rocroi (2005) the taxon is omitted again.

description

The gastropoda belonging to this taxon have branched tentacle-like nerves and two connecting strands.

Systematics

According to Ponder & Lindberg (1997) the Caenogastropoda and Heterobranchia form sister groups in the phylogenetic system and were combined to form the Monophylum Apogastropoda.

The Apogastropoda are classified in the taxonomy of Ponder & Lindberg (1997) as follows:

In the more recent taxonomy by Bouchet & Rocroi (2005) , however, the taxon of the Apogastropoda is no longer used. It is considered obsolete due to molecular biological reasons.
