Justification:
S. aradensis is relatively abundant but occurs in only three rivers and has a small range (area of occupancy (AOO) <2,000 kmĀ²). Water extraction, drought and the introduction of exotic fish species are threats to the three rivers and are causing a decline in habitat quality and number of mature individuals of S. aradensis.
