Paraphidippus basalis
(Banks, 1904)
Agave Jumping Spider
Paraphidippus basalis is a jumping spider in the Salticidae, commonly known as the Agave Jumping Spider. It is native to the southwestern United States and northwestern Mexico. The exhibits a notable ecological specialization, being strongly associated with rosette-forming plants including agaves, sotols, and yuccas. This degree of plant-specific association is uncommon among jumping spiders, which are typically .

Identification
Distinguished from other Paraphidippus by its documented association with agave and yucca plants; precise morphological diagnostic features require examination. The Paraphidippus can be separated from the similar genus Phidippus by subtle differences in genitalic structure and arrangement, though field identification to species level is challenging without microscopic examination.

Habitat
Strongly associated with rosette-forming plants, specifically agaves (Agave spp.), sotols (Dasylirion spp.), and yuccas (Yucca spp.). This plant-specific microhabitat specialization is atypical for salticid spiders.
Distribution
Found in Arizona and New Mexico, United States, and Sonora, Mexico. Records indicate presence in the Sonoran Desert and adjacent arid regions of the southwestern United States and northwestern Mexico.
Host Associations
- Agave - rosette-forming plants used as specialized microhabitat
- Dasylirion (sotols) - rosette-forming plants used as specialized microhabitat
- Yucca - rosette-forming plants used as specialized microhabitat
Ecological Role
Presumably a on small arthropods inhabiting agave, sotol, and yucca plants, though specific prey records are not documented in available sources.

Ecological specialization note
The strong association with rosette-forming plants (agaves, sotols, yuccas) represents an unusual degree of specialization among Salticidae, a whose members are typically habitat . The functional significance of this association—whether for prey capture, shelter, or —has not been explicitly studied.
Taxonomic history
Originally described as Phidippus basalis by Banks in 1904, subsequently transferred to the Paraphidippus.
