Assessment Information [top]

Red List Category & Criteria:	Endangered B2ab(ii) ver 3.1
Year Published:	2009
Assessor/s:	Hawking, J.
Reviewer/s:	Clausnizter, V. & Kalkman, V. (Odonata Red List Authority)
Contributor/s:
Justification: Listed by (Hawking 1999) as Endangered (EN), due to the extremely small distribution and the threat of water extracting for the nearby mining town, which has considerably lowered the water level of the Millstream Spring. This assessment still stands and the habitat continues to be under threat with the same problems.

Geographic Range [top]

Range Description:	This species is endemic to Australia. Distribution: Only known from the oasis of permanent waters, fed by the Millstream aquifer, along the Fortescue River, Pilbara, Western Australia (Watson 1969, Watson and Theischinger 1984).
Countries:	Native: Australia (Western Australia)

Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Occurs on streams and riverine pools; larvae found under stones in running water (Theischinger and Hawking 2006).
