The carapace is dark brown and the abdomen is brownish-black and marked with four light, nearly white streaks.

Phintella transversa is a jumping spider that was first described by Wanda Wesołowska and Anthony Russell-Smith in 2022.

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

[6] 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.

[7][8] In 2017, Jerzy Prószyński grouped the genus with 32 other genera of jumping spiders under the name Chrysillines in the supergroup Chrysilloida.

[1] The species can be identified by the pattern on the abdomen which differs from other spiders in the genus, like Phintella versicolor.
