Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-05-01
Assessor(s): Suhling, F. & Clausnitzer, V.

This is a widespread species with no known major widespread threats that is unlikely to be declining fast enough to qualify for listing in a threatened category. It is therefore assessed as Least Concern. In southern Africa, the species has a relatively wide distribution, occurring in river catchments of the Zambezi and Limpopo. Its occurrence outside the southern Africa region (record from Tanzania) has still to be confirmed.
Previously published Red List assessments:
2007 Least Concern (LC)
2006 Least Concern (LC)

Geographic Range [top]

Range Description:The species has been recorded from Transvaal to Mozambique, Zambia, and probably Tanzania.

In eastern Africa, it has been recorded in Kenya, Tanzania, Uganda, Malawi and Burundi: unconfirmed record from southern Tanzania.

In southern Africa, this species may be endemic to the southern Africa region. It occurs in the river catchments of the Zambezi and the Limpopo (Botswana, Mozambique, South Africa (Transvaal), Zambia, and Zimbabwe). However, there is also an unconfirmed record from Tanzania. In South Africa, there are only two records: Pafuri, Kruger National Park, and Ndumo, KwaZulu-Natal (Samways 2006).
Countries occurrence:
Botswana; Burundi; Kenya; Malawi; Mozambique; South Africa; Uganda; Zambia; Zimbabwe

Population [top]

Population:No information is available on overall population size or trends. It appears to be a localised species throughout its range (Samways 2006).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Rivers in bush, woodland, savanna. Tall grass and other low vegetation near wide, meandering rivers (Samways 2006).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): In South Africa, major changes to the river systems of the Kruger National Park as a result of the floods of February 2000 may have altered its habitat, particularly that of the larvae (Samways 2006). No information is available from elsewhere in its range.

Conservation Actions [top]

Conservation Actions: In South Africa, further searches for the species are required (Samways 2006). No specific conservation measures are known to be in place or are planned at present.
