Phintella occidentalis is a species of jumping spider in the subfamily Salticinae that lives in Ivory Coast.

First described by Wanda Wesołowska and Anthony Russell-Smith in 2022, the species is named after the Latin word for western as it is found in West Africa.

The abdomen is yellow and is marked by two wide brown stripes on the female and a grey streak on the male.

[6] There are similarities between spiders within genus Phintella and those in Chira, Chrysilla, Euophrys, Icius, Jotus and Telamonia.

[7] Genetic analysis confirms that it is related to the genera Helvetia and Menemerus and is classified in the tribe Chrysillini, named after the genus Chrysilla.

[8][9] In 2017, Jerzy Prószyński grouped the genus with 32 other genera of jumping spiders under the name Chrysillines in the supergroup Chrysilloida.

The epigyne is small and has seminal ducts that initially diverge before converging on large spherical spermathecae.

Superficially, the copulatory organs are similar to the related Phintella popovi but the length of the tibial apophysis on the male and morphology of the seminal ducts on the female can help tell the two the species apart.
