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 box
- male parameres conchoid and asetose (in rare cases, e.g. Pseudamara arenaria, parameres have some apical setae)
- mandible lacking scrobal seta (various taxa may have numerous short fine setae in the scrobe and in rare cases, e.g. Metius robustus, there may be a single more substantial seta. However, this condition is recognizably different than the single robust fixed seta in the scrobe of non-harpalinae taxa)
- Configuration of abdomen:Tergum VIII partially or totally invaginated with anterolateral apophyses present. Pygidial gland opening near the posterior margin of tergum VIII.
- most species spray hydrocarbons and formic acid in defense secretions (Moore, 1979)
- male chromosome number in most species 2n=36+x
- high-grade wedge-pushing ability
