The male

Young females and adult males lack the pair of large abdominal spurs and the bright colours that characterize the adult females. They also have an unusual sparse pattern of large body hairs which are less prominent on the body of an adult female and gradually disappear as she approaches maturity.

Known Range: Though most common in near-coastal bush and garden settings in Queensland this species probably has a much wider range, particularly in northern areas.

Spider(s) with a very similar appearance: Other jewel spiders, such as Austracantha minax and Gasteracantha quadrispinosa.
