Etymology.

The specific name comes from the Kurrama word martamarta, meaning red in the language of the indigenous Kurrama people of the region, and refers to the red color of this species (Fig 93). The name is to be treated as a noun in apposition.

Diagnosis.

Females of this species can be differentiated from all others by the indistinct median septum and lateral lobes, and the median field being a long, narrow depression, with round spermathecae, and the sperm ducts nearly touch medially (Figs 45-46). Male is unknown.
