The identity of this spider is based on the contents of the following paper: Otto J.C. and Hill D.E. (2011) "An illustrated review of the known peacock spiders of the genus Maratus from Australia, with description of a new species (Araneae: Salticidae: Euophrynae) PECKHAMIA 96.1, 1-27.

The males of most Maratus species have unique and brightly coloured dorsal markings but the females are a drab grey-brown colour and that is certainly true for M. pavonis. Note that there is no question that the female shown above and the last male in the set are the same species because they were found at the same time and within 20 cm of each other and the male has Leg III raised as a courtship signal.

Another unusual characteristic of the male of this genus is the presence of side flaps attached to the upper sides of the abdomen, these spreading sideways like a fan when the male is courting the female, a phenomenon that is even more pronounced on the closely related species, Maratus volans. This fan display is thought to be induced hydraulically, although the spider also tends to extend the abdomen and each Leg III upwards and to the rear as part of its courtship behaviour.
