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 Huber (2000) modified after the results of Bruvo-Madaric et al. (2005)
Containing group: Pholcidae

Characteristics

The New World clade includes a quite heterogeneous group of pholcid genera; all of them, as the name of the clade indicates, are known from the New World. Spiders in this group also share some morphological synapomorphies such as the exposed tarsal organ, male palpal coxa with a retrolateral apophysis, large distance between the posterior median and the anterior lateral eyes, male gonopore without epiandrous spigots and anterior lateral spigots with only one piriform gland each.

Discussion of Phylogenetic Relationships

The exact limits of this group are still unclear. A fairly large sample of New World genera was included in two phylogenetic studies (Huber, 2000; Bruvo-Madaric at al., 2005) but both failed to find an unambiguous solution for the exact limits of this group and the internal relationships of the included genera. Therefore, “New World clade” is used as an informal name referring to the group of New World pholcid genera found to be more closely related to each other than to the rest of the genera in the family. Addition of more data and expanding the taxon sample may help to answer these questions. Several genera which have some of the New World clade synapomorphies are listed here but their position was not tested in a phylogenetic analysis.

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.
