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
Much of the Pelegrina section of the Tree of Life is based on the revision by Maddison (1996). That revision contains many more illustrations, keys and full descriptions.
The following characters support the monophyly of the genus, though none provides a simple, strict delimitation (Maddison, 1996). Some of the characters delimit a group slightly smaller than the genus, others a group slightly larger. Thus, each character provides only indirect and partial evidence for monophyly.
- Embolus with two terminal rami retrolateral to opening. The sperm duct opening lies on the prolateral side of the embolus, often below the tip. Retrolateral to the opening are two rami, one just distal to the opening; the other often elongate and forming the retrolateral tip of the embolus.
- Hematodocha of embolus bulges as far distally as the base of the erect portion of the embolus.
- Epigynal flaps well developed, long and wide, and not descending into the opening posteriorly.
- Wrinkles present on anterior margin of male cheliceral fang.
- Distinct cheek bands on the male face.
- An inverted V-shaped mark of pale scales on the forehead, contacting the AME.
- Male courtship with prolonged "crouch" display.
- Ridge under tibial apophysis.
