A new species of Depressizona and the family rank of Depressizonidae

Mollusca Depressizona Depressizonidae

Abstract

The microscopic scissurellids are being currently revised; scissurellids is used here for the small Vetigastropoda formerly classified in Scissurelloidea, but which has been shown to be a polyphyletic assemblage (e.g., Geiger 2008, Geiger & Thacker 2005). Geiger (2003) presented an overview, where the new monotypic subfamily, genus, and species were introduced: Depressizoninae with Depressizona exorum Geiger, 2003. Here a second species in the genus is described, which also helps to justify the family-level rank of the group.
