On 29 December 2023 Jurgen Otto and David Hill described Maratus yanchep in Peckhamia 311.1. The species stands out in particular by its variability, each known individual looking strikingly different. The species which leaves in the Yanchep area north of Perth was discovered by Reef Coakley, Lucyna Kania and Nick Volpe. At the time of writing the only known location it has been found in is earmarked for extensive development.
