Clinidium (Clinidium s. str.)

Ross T. Bell
Containing group: Clinidium

Introduction

Clinidium s. str. is the largest subgenus with 48 species found in the Andean region of South America, with a few species in Amazonia but none in coastal or southern Brazil. This group is also found in the Greater and Lesser Antilles and in Central America north of Guatemala.

Characteristics

The antennal stylet is relatively large. Tufts of minor setae are on antennal segments IV-X, V-X, VI-X, VII-X, or else entirely absent. There are 1-4 temporal setae. The eye is very narrowly crescentic in most species. In a few it is bilobed or divided into anterior and posterior ocellus-like portions. In one species it is large and hemispherical.

The marginal groove of the pronotum is single. The pronotum has an angular seta and one or more marginals. Some species also have discal or basal setae. The elytral striation is reduced, and the marginal stria is fourth or fifth from the suture. The inner intervals are flat to convex but never carinate. The elytral setae are numerous in most species. The base of the anterior tarsus is opposite of the cleaning organ.

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.
