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: Carabidae

Characteristics

This informal group of carabids is characterized by a derived feature of their middle coxal cavities, in which the mesosternum and metasternum surround the mesocoxae, forming both the mesal and lateral walls of the coxae. Such mesocoxal cavities are called "conjunct", and they give this group its name. In contrast, most carabids outside of this group have disjunct mesocoxal cavities, in which the the lateral wall of the cavity is formed in part by the mesepimeron (the sterna thus being disjunct on the lateral wall of the cavity). Outside of the Carabidae Conjunctae, the only carabids with conjunct mesocoxal cavities are the Notiophilini and some Paussini (Kavanaugh and Nègre, 1982; Beutel, 1991).

In addition, the posterior edge of the metepimeron of these carabids is lobed, and partly overlaps the first visible abdominal sternum.

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.
