Remarks. This interesting species was described from three different bores in the Robe River aquifer, southwestern Pilbara ( Karanovic 2006). Only two additional samples were collected subsequently, one also from the Robe River aquifer and the other from the nearby Fortescue River, which extends its known distribution slightly northwards. However, its range is still less than 50 km in diameter, which suggests that it is a short range endemic. No new variability was recorded in these newly collected specimens.
