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.

phylogeny from Klimaszewski (1979)
Containing group: Aleocharinae


The Deinopsini are a small group of teardrop-shaped basal aleocharines that are characteristic inhabitants of marshes, bogs, pond and stream edges and similar riparian habitats. Deinopsine taxa occur in the Nearctic, Palearctic, Neotropical, Ethiopian, Oriental, and Australian faunal regions.


Deinopsines are similar to members of the Gymnusini, but they may be recognized by the combination of:

The three genera are superficially very similar, but they differ markedly in structure of the mouthparts, tarsi and genitalia.

Discussion of Phylogenetic Relationships

Klimaszewski (1979) provided a reconstructed phylogeny of the genera of the Deinopsini, and later (1980, 1982, 1985a,b 1992) he described more species and supplemented his revision. He proposed that the tribe is monophyletic based on the presence of a divided male tergum IX, and female sternum IX with 2 lobes and without valvulae. Among the four genera included in the tribe, he proposed that Metadeinopsis was the basal lineage and that Adinopsis and Deinopsis were sister groups based on derived features of the male copulatory organ and the presence of an elongate apical portion of tergum X in both males and females of these latter two genera (see Klimaszewski 1979 for details).

Recently, Ashe (2002) described Allodinopsis from Central America as a new genus. Though Ashe (2002) pointed out the striking similarities between Allodinopsis and Metadeinopsis, and hypothesized that they are very closely related, the phylogenetic placement of Allodinopsis has not been rigorously examined.

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.
