Maratus mungaich, the banksia peacock spider,[citation needed] is a species of jumping spider in the family Salticidae.

[2] It is endemic to Western Australia.

[2] The species was first described in 1995 by Julianne Waldock.

[4] In courtship, males in the Maratus genus extend their elongated third legs,[5] and only the male is so brightly and beautifully coloured.

The specific epithet, mungaich, derives from a Nyoongar word for "banksia"[1][6] (mangatch).
