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.

IntroductionThis group is restricted to southern South America where they are frequently one of the most abundant groups of ground beetles. They have several extremely different body forms with Abropus being very platynine-like and most Metius are very harpaline-like. Most Metius are heavily-built ground dwelling species, while Abropus is commonly found on the ground and climbing on vegetation.
CharacteristicsAll metiines share the absence (Fig A.) of the suture between the mentum and submentum, which is present in other pterostichines (Fig. B).
All members except Feroniola species have setose paraglossae (Fig. A), while the more common condition in pterostichites is glabrous (Fig. B).
Discussion of Phylogenetic RelationshipsDNA sequence data place this group as sister to the Notonomus series (K.Will unpublished).
