Scientific Name: Stenocypha hasta (Pinhey, 1960)
Common Name(s):
English Mahale Jewel
Chlorocypha hasta Pinhey, 1960
Chlorocypha molindica ssp. hasta Pinhey, 1960
Taxonomic Source(s): Schorr, M. and Paulson, D. 2014. World Odonata List. Tacoma, Washington, USA Available at: (Accessed: 17 February 2014).
Taxonomic Notes: Pinhey (1967) regarded C. hasta Pinhey, 1960 as a subspecies of C. molindica Fraser, 1948. Dijkstra (2007) considers C. hasta as a good species and as closely related to C. tenuis Longfield, 1936, of which it might even be a synonym.

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2009-05-01
Assessor(s): Clausnitzer, V.
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)
The species is listed as Vulnerable VU B1a,b(iii) due to its extent of occurrence (EOO) under 2,000 km², and only a part of the range is within a protected area. All the records (four localities) are around the Mahale Mountains along the eastern shore of Lake Tanganyika. There is no information on decline in habitat quality or extent either inside or outside the national park, but impacts are inferred and expected from aerial survey (Clausnitzer pers. comm.). It was previously assessed as Data Deficient due to lack of information.

In eastern Africa, this species is known only from the type locality "Lugubwe River, near Kasangazi". It was not stated whether the specimens were lacustrine or riverine. More surveys are needed to get information about the habitat, the extend of occurrence, area of occupancy and taxonomy (possible synonym to C. tenuis Dijkstra 2007). If the species remains an endemic of the eastern shores of Lake Tanganyika, it is most likely to be listed as Endangered or Critically Endangered.

Geographic Range [top]

Range Description:All the records are around the Mahale Mountains along the eastern shore of Lake Tanganyika.

It is not found in the central Africa region, but this might be due to sampling deficiency around Lake Tanzania. More sampling is also needed to check, whether C. tenuis and C. hasta are two species or synonyms (see Dijkstra 2007).

In eastern Africa, it has been recorded from "Lumbugwe River, Kasangazi", eastern shores of Lake Tanganyica (Tanzania).

Conservation Actions [top]

Conservation Actions: No conservation measures known but information on taxonomy, population ecology, habitat status and population trends would be valuable.
