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: Dioptinae


A diverse, almost exclusively neotropical tribe containing many species with wing patterns mimicking those of butterflies, Arctiidae and Geometridae.


Although the tribe is clearly monophyletic based upon the structure of the thoracic tympanal organ and other structures, Miller (2009) was unable to discover any uniquely derived and unreversed synapomorphy uniting the Dioptini. He notes two features shared by several genera within the tribe: long, sickle-shaped labial palpae, and the presence of male forewing stridulatory organs. However, both of these features are scattered among diverse genera. He suggests the presence of curled or curved setae on the abdominal venter of the pupa as a potential synapomorphy for the tribe, but immature stages are known for so few taxa that this remains a speculation.

Discussion of Phylogenetic Relationships

Hypothesis of relationships based on Miller's (2009) cladistic analysis of morphological characters of exemplar taxa, with some taxa not included in that analysis added at their presumptive positions based on the discussion in the text.

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.
