Apodera vas is one of the most common Nebelids in the southern hemisphere, but so far it has not been found in Europe or North America. This genus was proposed by Jung (1942) without type designation. This was corrected by Loeblich & Tappan (1961). Three species, type: Apodera vas Certes, 1889.


Shell subspherical or ellipsoidal, compressed, constriction between body and swollen neck which tapers from its junction with the body towards the aperture, neck. Aperture oval, slightly arched. Shell composed of collected or predated euglyphid idiosomes in an unstructured cement, transparent. Ovular nucleus.

Discussion of Phylogenetic Relationships

Lara et al. (2008) have shown in a SSU rRNA tree that Apodera vas is closely related to Nebela lageniformis from South America (Peru).


Apodera species live in mosses (often Sphagnum), litter and organic soils. They feed on a wide range of foods including algae and small Euglyphida like Euglypha, Trinema, Corythion or Tracheleuglypha.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
