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.

Tree from Griswold (1987).
Containing group: Habronattus

Introduction

The agilis group includes a number of very similar species sharing a large carapace-abdomen stridulatory apparatus (Maddison and Strattion, 1988) and vertically fringed first legs in males. They tend toward sandy habitats, and can dig into sand to build retreats beneath the surface.

Characteristics

The most striking characteristic of the agilis group is the stridulatory apparatus between the carapace and abdomen of males:

The first legs of males have vertical fringes and are held to the side during courtship:

The faces of males are white to red or black and have tufts of hairs on the sides that blend with the fringe of hairs of the first femur:

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.
