Scientific Name: Acisoma ascalaphoides
Species Authority: Rambur, 1842
Common Name(s):
English Littoral Pintail, Grizzled Pintail
Acisoma inflata Selys, 1882
Acisoma panorpoides ssp. ascalaphoides Rambur, 1842

Taxonomic Notes: The type locality for Acisoma panorpoides ascalaphoides is Madagascar. It is not currently certain that the populations of Madagascar and mainland Africa are similar (K. Schütte in Dijkstra and Boudot 2010), so it is likely that the present subspecific name will have to change in the future for Africa.

This species previously appeared on the IUCN Red List as Acisoma panorpoides ssp. ascalaphoides but it has now been promoted to Acisoma ascalaphoides. An updated Red List assessment has been produced to reflect the change in name.

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2012-02-13
Assessor(s): Boudot, J.-P., Clausnitzer, V., Suhling, F., Samraoui, B. & Schneider, W.

Facilitator/Compiler(s): Alomari, K.
Acisoma ascalaphoides is listed as Least Concern in view of its wide distribution, and because it is unlikely to be declining fast enough to qualify for listing in a threatened category. However, disjunct areas in northern Africa and southern Africa deserve special attention.

Geographic Range [top]

Range Description:Acisoma ascalaphoides is widespread in Africa (except dense rain forest), and also present in Oman in the Arabian Peninsula. In Africa, its distribution extends mostly from South Africa to the southern border of the Sahel, and from the Senegal to Ethiopia. Disjunct populations are known further north in Algeria, Libya and Egypt, and in the south of the Arabian Peninsula. These populations are believed to represent relicts from the Early Holocene Pluvial Period, which culminated around 8,000-10,000 BP, during which the Sahelian, Saharan and Arabian belt bore a mix of Savannah and gallery forests along permanent wadis. The subsequent aridification which began at the mid Holocene led to the fragmentation of an originally continuous range.

Population [top]

Population:Population size is unknown but in view of the extent of the sub-Saharan African range of the species, it should be large.
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:Unknown
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species is mostly known from swampy and well-vegetated open freshwater habitats.
Systems:Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): No major threats are known for this species at the global level. Drainage and destruction of swampy habitats as well as water abstraction and pollution may be a potential threat in some parts of its range, particularly in the disjunct areas in the north of Africa and in the south of the Arabian Peninsula.

Conservation Actions [top]

Conservation Actions: No general conservation plan is needed at the global scale, but the disjunct localities from the north of Africa and the south of Arabia should be strictly protected. Monitoring is urgently needed in these areas.
