Introduction

Certesella is a very conspicuous genus which is restricted to the southern hemisphere. It was proposed by Jung (1942) as Penardiella without type designation (Loeblich & Tappan, 1961). Four species, type species: Certesella martiali (Certes, 1889).

Characteristics

Shell flask-shaped, compressed, neck with parallel sides, organic apertural rim. In broad view on each side two pores in depressions connected by an internal tube like in Porosia bigibbosa. Neck with one or two internal organic thickenings and rows or groups of teeth at both sides. Scanning electron microscopy reveals surface to be relatively smooth. Shell transparent, composed of collected euglyphid idiosomes in an unstructured organic cement.

Ecology

The prefered habitat is wet Sphagnum moss.

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.
