Habronattus viridipes 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.close box
The H. viridipes group consists of those species with modified first and third legs that lack the secondarily straightened tegular apophysis characteristic of the H. coecatus group.
Like the coecatus group, the viridipes group has a fringed first leg and modified third leg.
(the placement of forticulus and velivolus is not clear).
These two subgroups show distinctively different courtship behaviors (Maddison, unpublished). The viridipes group proper has a raised v of scales between the back eyes; the clypeatus group has a more prominent stridulatory organ. Some preliminary molecular data (Hedin and Maddison, unpublished) and aspects of the ornamentation hint that the clypeatus group may be more closely related to the coecatus group than to the virdipes group proper.
