Containing group: Rhyzodiastes


Rhyzotetrops is a subgenus with a single species from Fiji.


Each compound eye is divided into two well-separated, ocellus-like structures, one anterior to the other. This remarkable four-eyed condition is duplicated in Clinidium (s. str.) beccarii and related species.

Rhyzodiastes (Rhyzotetrops) janus. (A) Dorsal aspect of head and pronotum. (B) Head (lateral aspect).
Modified from Bell and Bell (1985). Copyright © 1985 Ross T. Bell and Joyce R. Bell.

The elytron has an intercalary stria. The apical stylet of the antenna is acuminate. The antennal tufts are limited to segments VII-X. The clypeal setae are present. The median groove of the pronotum is strongly dilated. The inner carinae slope gradually into the paramedian grooves, which are glabrous except for a strip of pollinosity along the medial margin of the outer carina. This margin is curved and of even width, and it carries a row of setae. The intra-tubercular stria is obsolete except for the apex, which is impressed. All femora have many long setae.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into 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.
