Habronattus agilis groupWayne Maddison
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.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

IntroductionThe 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.
CharacteristicsThe 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:
