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: Euchroina


    Members of the primarily Neotropical genera Pseudabarys, Neotalus and Abaris are relatively small ground beetles, most individuals are brilliantly metallic with very prominent eyes. These characteristics give them a unique look that is very similar to the Australian genus Prosopogmus.
    A few of the abariform species have been treated taxonomically. Straneo (1939) published a key to the eight then named species of Abaris and Bousquet (1984) added a ninth species when he discovered that LeConte’s Pterostichus splendidulus belonged in the genus Abaris. Bousquet and Liebherr (1994) summarized what little had been published on the relationships of the genus Abaris and covered nearly all the genera included herein. Will (2002) revised Abaris and Neotalus, providing a key to species and biogeographic analysis for the group.


Inlcuded taxa have characteristics of Euchronia and very prominent eyes. Abaris species are uniquely characterized among all Pterostichine grade taxa by pectinate claws.

The combination of large eyes, pectinate claws, and metallic luster suggests that Abaris species may have peculiar life histories or behaviors relative to related genera that have characteristics more typical for pterostichine grade taxa. However, the limited field observations for these species do not provide incontrovertible evidence for any adaptive significance for this suite of characteristics. Both Abaris and Pseudabarys are collected in leaf litter, sometimes in or near fallen rotten fruits or flower petals.

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.
