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.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

close boxIntroduction
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.
Characteristics
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.

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.
