Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA ARTHROPODA INSECTA ODONATA LIBELLULIDAE

Scientific Name: Trithemis grouti
Species Authority: Pinhey, 1961
Common Name(s):
English Black Dropwing
Synonym(s):
Trithemis atra Pinhey, 1961
Taxonomic Notes: The subspecies T. grouti atra is from central Africa. T. grouti has priority over T. atra by two months (Pinhey 1984). This correction has sometimes been overlooked (e.g., Legrand 2003). All records of T. nuptialis in western Africa probably pertain to this species.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-05-01
Assessor(s): Clausnitzer, V., Suhling, F. & Dijkstra, K.-D.B.
Reviewer(s): Dijkstra, K.-D.B., Clausnitzer, V., Suhling, F., Samways, M., Samraoui, B., Boudot, J.P., Kipping, J. (Odonata Red List Authority) & Allen, D. (IUCN Freshwater Biodiversity Unit)
Justification:
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 central, eastern and western Africa, the species 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.

In southern Africa, this appears to be a forest species, which may be threatened by habitat degradation. Current data suggests that the range within southern Africa is marginal. A small percentage (<5%) of the global range for this species falls within the region (based on current data). More research is needed to gather data on range, population status, etc., but for the regional Red List, it is currently Not Applicable.
History:
2009 Least Concern
2008 Least Concern (IUCN 2009.2)
2006 Least Concern (IUCN 2006)
2006 Least Concern

Geographic Range [top]

Range Description: The species is very widespread, with subspecies atra in Uganda and Zambia to Gabon, and the nominate subspecies in Nigeria, Cameroon and Congo.

In central Africa, it is known from Cameroon, Democratic Republic of Congo, Equatorial Guinea, Gabon, Zambia, records from Angola and Congo are likely but need confirmation.

In eastern Africa, it has been recorded from Kenya, Tanzania, Uganda (forest), Malawi and Burundi.

In southern Africa, the species is recorded from northwest Zambia (Upper Zambezi catchment). The last records of the species date back to 1960. It is estimated that less than 5% of the global range occurs within the southern Africa region.

In western Africa, the species is known from Gambia to Nigeria.
