Etymology. The specific name is a patronym in honour of Julianne Waldock, for her contributions to Maratus systematics over more than two decades. She also provided excellent support for Madeline Girard in finding Maratus localities.

Diagnosis. This species belongs to the Maratus anomalus group, sharing a pair of large patches of white setae on the posterior sides of the prosoma, with an embolic disc which has a smooth narrow front with a retrobasal knee-shaped structure and a long narrow embolic tip with the embolic opening at the posterior distal part and a thin semicircular lateral process of embolic disc with a narrow retrolateral fold.

Maratus julianneae can be separated from M. michaelorum and M. anomalus by the pattern of the opisothosoma. M. michaelorum has a pattern of a heart-shaped circle and two elongated patches of golden orange setae in the centre and M. anomalus has a completely bluish iridescent opisthosoma, whereas Maratus julianneae has a grey-whitish opisthosoma with bluish iridescent sides at the posterior third.
