jumping spiders, outside the Salticoida

with Lapsias, or if the common characteristics are symplesiomorphic.
Spider
Spiders are air-breathing arthropods that have eight legs, and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms...

Phylogeny
Lapsias, GalianoraGalianora
Galianora is a genus of jumping spiders.The two described species have quite a different body form: G. sacha is elongate and pale, with raptorial front legs, while G. bryicola is compact and brown. An as-yet undescribed species from Venezuela is intermediate in body form and palpus.-Name:The genus...
and Thrandina
Thrandina
Thrandina is a genus of jumping spiders, with the single species Thrandina parocula, which is found in Ecuador. It is unique among New World salticids in having strikingly large posterior median eyes....

Basal (phylogenetics)
In phylogenetics, a basal clade is the earliest clade to branch in a larger clade; it appears at the base of a cladogram.A basal group forms an outgroup to the rest of the clade, such as in the following example:...
jumping spiders, outside the Salticoida
Salticoida
The Salticoida are a group of jumping spiders. Most salticid genera belong to this unranked clade, with all others believed to be basal to the Salticidae.Among the subfamilies in this clade are the following:...

Clade
A clade is a group consisting of a species and all its descendants. In the terms of biological systematics, a clade is a single "branch" on the "tree of life". The idea that such a "natural group" of organisms should be grouped together and given a taxonomic name is central to biological...
