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: Histeridae

Introduction

The Chlamydopsinae is one of two exclusively inquilinous subfamilies of Histeridae (along with Hetaeriinae). This is probably the most poorly known of all histerid groups, although it has received some important recent attention (Caterino, 2000; Degallier and Caterino, in prep). Chlamydopsinae are rather restricted in distribution. Most of the described species are Australian, although additional species have been described from India, Japan, Taiwan, Indonesia, and New Guinea. It is likely that many new species will be found throughout mainland and insular southeast Asia.

Characteristics

The main synapomorphy of the subfamily is also its best diagnostic character: the antennal scape is inserted high on the frons, above the eye, and is expanded such that it completely hides the eye when the head is withdrawn (the name Chlamydopsis means ‘covered eye’).

Discussion of Phylogenetic Relationships

Relationships within Chlamydopsinae are currently being investigated. Pheidoliphila, Orectoscelis, Ceratohister, Eucurtiopsis, and Gomyopsis together clearly form a monophyletic group. In all of these the scutellum is hidden by the posterior margin of the pronotum, a strong synapomorphy. Whether the remaining genera form the sister group of this one or are paraphyletic with respect to it is not yet clear. The generic limits within the group are also currently in flux. The monophyly of Chlamydopsis and Orectoscelis is particularly doubtful.

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.
