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.

Tree after Bell and Bell 1985
Containing group: Clinidium


Arctoclinidium is a holarctic subgenus with nine species, five from the eastern U.S. and one each from western North America, Japan, the Caucasus, and southern Europe.


The base of the anterior tarsus is opposite of the cleaning organ. The antennal stylet is small. Tufts are present on antennal segments VI-X (C. veneficum) or VII-X (all other species). The number of temporal setae is 1 or 0. The eye is crescentic. The orbital groove is complete and joined posteriorly to the marginal pollinosity of the temporal lobe.

Modified from Bell and Bell (1985). Copyright © 1985 Ross T. Bell and Joyce R. Bell.

The marginal groove of the pronotum is double or single. The angular seta is absent (except in C. marginicolle). There are no marginal setae. The marginal stria of the elytron is the sixth from the suture. The inner intervals are convex or costate. There are very few elytral setae restricted to the posterior part of the elytron. The female has enlarged lateral pits on sternum III or IV or both III and IV.

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.
