This is a widespread species with no known major widespread threats and that is unlikely to be declining fast enough to qualify for listing in a threatened category. It is assessed as Least Concern.
Previously published Red List assessments:
2009 Least Concern (LC)
2006 Least Concern (LC)

Geographic Range [top]

Range Description:The species has been recorded from Sudan to Botswana and Nigeria. It is much scarcer than other Brachythemis. Principally, it is found in the savannah belt, with records from Bukina Faso, Cote d'Ivoire, Togo, Nigeria, Sudan, Democratic Republic of Congo and Uganda. Its presence in Botswana is isolated but confirmed. Also known from a narrow band across the southern Sahel, with an isolated population in the Okavango, which requires further investigation.

In central Africa, it is recorded from the Democratic Republic of Congo, Cameroon, Central African Republic, and assumed from Congo.

In eastern Africa, it is present in Kenya, Tanzania, Uganda (Laropi, West Nile), Malawi and Burundi.

In northeastern Africa, the species is listed by Tsuda for Sudan, although this record needs confirmation. Occurrence in northern Kenya is likely to be valid too.

In southern Africa, this species is only known from the Okavango Delta, Botswana. This population is far from other populations outside the region and there may be some taxonomic investigation required to determine whether this is a separate species.

In western Africa, the species is known from Burkina Faso, Cote d'Ivoire, Togo and Nigeria.

Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Swampy streams and rivers in bush (Pinhey 1976; Kipping, pers. comm.).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Potentially drainage and destruction of swampy habitats due to agriculture and water pollution are major threats to the species.

Conservation Actions [top]

Conservation Actions: Three records are from within wildlife management areas, but outside National Park areas. Only one record falls outside the management area. More research is needed to gather data on taxonomy, range, population status, and threats.
