Red List of South African Species

Least Concern (LC)

Rationale

Pseudagrion hamoni is a widespread species with no known major threats and it is unlikely to be declining fast enough to qualify for listing in a threatened category. It is therefore assessed as Least Concern. It appears to be under threat only in the disjunct localities in north Africa due to aridity and isolation preventing immigration from southern regions.

Distribution

This Afrotropical species is widespread and often common from the northern half of South Africa to western Africa (Senegal, southern Niger and southern Mali) and Kenya. Records of P. sjoestedti from Guinea-Bissau by Schmidt (1951) may pertain to this species. Further north, this species shows a string of disjunct localities in Mauritania, south Algeria, south Libya, northeastern Chad and Sudan, which are mostly relicts from the Early Holocene pluvial period (Dumont 1982, 2007). Further east, Pseudagrion hamoni extends to the southwestern margin of the Arabian Peninsula in Yemen and Saudi Arabia.

Population trend

Trend

There is no information available on the population size or trend at a global level.

Threats

Drying up of the relictual wadis in the Saharan and Arabian belt due to droughts, drainage and destruction of habitats caused by agriculture, surface and groundwater extraction and water pollution are all local threats to this species. No major global threats are known.

Uses and trade

This species is not utilised.

Conservation

In its north African disjunct and relictual localities, it is present in an area which has been poorly inhabited since the middle of the Holocene and the present aridity and exhaustion of water resources is a natural climatic event. Policy-based actions are recommended, as well as increasing awareness only in these relictual localities, with establishment and management of protected areas. Research into biology and ecology, habitat status and threats, and population trend monitoring would be valuable.
