TYPE: Male holotype taken in dry pitfall trap at Bidgemia Station, Gasgoyne Junction , 258039S, 1158189E, Western Australia (June 3–8, 1995; J. Waldock), deposited in WAM (96/712) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males can be recognized by the dorsally excavated retrolateral tibial apophysis and the wide lateral prong of the terminal apophysis (figs. 698, 699), females (which have not been collected together with males, but which match them in size and col­ or pattern) by the heart­shaped epigynal atrium (fig. 700).

MALE: Total length 4.5. Abdominal dorsum with large posteromedian white spot above spinnerets, venter with four longitudinal rows of small, circular, orange sclerites. Leg spination typical for genus. Retrolateral tibial apophysis dorsally excavated (fig. 699); median prong of terminal apophysis narrow for most of its length, lateral prong wide, embolus relatively short (fig. 698).

FEMALE: Total length 4.7. Abdominal dorsum as in male, venter with two longitudinal rows of small, circular, orange sclerites. Leg spination typical for genus. Epigynal atrium large, heart­shaped (fig. 700); median epigynal ducts widely separated (fig. 701).
