Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Introduction

Rhysodes is a palaearctic genus with two species.

Characteristics

The antenna has a well-developed apical stylet, and there are minor setae on antennomeres VI-X. There are four setae on the labrum. The temporal lobes are kidney-shaped and have two medial angles separated by emargination. The median lobe is narrow, and its posterior part is slightly widened. The orbital groove is complete and reaches the occiput. The pronotum has deep basal impressions which are open posteriorly. The impressions are preceded by fine discal strioles which extend 95% of the distance to the anterior margin. The pronotum has angular setae but no marginal setae. The elytron is without a humeral tubercle.

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.
