Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA ARTHROPODA INSECTA ODONATA SYNLESTIDAE

Scientific Name: Ecchlorolestes peringueyi
Species Authority: (Ris, 1921)
Common Name(s):
English Marbled Malachite

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2010
Date Assessed: 2007-04-01
Assessor(s): Samways, M.J.
Reviewer(s): Simaika, J.P., Kipping, J., Suhling, F. (Odonata Red List Authority) & Pollock, C.M. (IUCN Red List Unit)
Justification:
Earlier last century, Ecchlorolestes peringueyi was known from many more localities than are known at present. It is now known from several localities, all within protected areas. Its population appears to have stabilized, however it still has a restricted range and it is kept in the Vulnerable category until it can be certain that the population is showing a real recovery. Ongoing alien riparian tree removal is important to this species.
History:
2007 Vulnerable
2004 Vulnerable
1996 Endangered
1994 Rare (Groombridge 1994)
1990 Endangered (IUCN 1990)
1988 Endangered (IUCN Conservation Monitoring Centre 1988)
1986 Endangered (IUCN Conservation Monitoring Centre 1986)

Geographic Range [top]

Range Description: The species is endemic to South Africa. It is only known from the mountains in the West Cape, this species could never have been abundant as it is such a habitat specialist. From early records (Pinhey 1984) it was nevertheless at many more localities than it is today, having disappeared in particular from the Rawsonville area. Today it is known only from small, boulder-filled streams in the upper reaches of small rivers in the Cape Fold mountains (Samways 2006 in press).

Population [top]

Population: Population size is unknown, however its population appears to have stabilised in both range and size.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: The species is now known from several locations with clear, shallow streams with an abundance of large, lichen-covered boulders (Samways 2006 in press).
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): There are several threats which are also synergistic. Alien invasive trees (pines and Acacia longifolia) shade the habitat and alien invasive rainbow trout are predators. The former threat of habitat removal (mostly for plantation forestry) has largely subsided.

Conservation Actions [top]

Conservation Actions: The population occurs within protected areas (Hottentots-Holland Reserve, Kogelberg Nature Reserve, Cedarberg Nature Reserve, Table Mountain National Park). Population levels should be monitored regularly. There must be no further encroachment of plantation forestry or introduction of trout. Fish-farming enterprises in Jonkershoek and Du Toit' s Kloof are of concern. The removal of alien invasive trees, is of great benefit to this species.
