Introduction

Stephanopogon apogon is one of two species in the genus that has been studied at both the ultrastructural and molecular phylogenetic levels. This was the first species to be described with the aid of transmission electron microscopy, and these studies demonstrated that Stephanopogon was not a member of the Ciliata (Lipscomb and Corliss 1982; Patterson and Brugerolle 1988). A culture of S. agpogon containing the euglenozoan Rhynchomonas nasuta as a food source is available at the American Type Culture Collection ATCC (50096).

The molecular phylogenetic position of this species was addressed using both actin and small subunit ribosomal RNA gene sequences; this study showed that S. apogon is closely related to the heterolobosean Percolomonas cosmopolitus (Yoon et al 2008).

Characteristics

Stephanopogon apogon has a slit-like apical cytostome, but lacks the prominent apical barbs present in other species in the genus.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into 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.
