This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

Containing group: Zoraptera

Introduction

The extinct subgenus Octozoros includes two middle Cretaceous species, both known from alates in Burmese amber (Engel and Grimaldi, 2002; Engel, 2003).

The Burmese amber species Zorotypus cretatus may belong to Octozoros but the holotype is too imperfectly preserved to permit definitive placement here. The species is, therefore, retained as incertae sedis within Zorotypus s.l.

Characteristics

The subgenus Octozoros can be recognized by the following suite of apomorphic traits (Engel, 2003):

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.
