 (Megapodagrionidae). This species is commonly known as the Amani flatwing.

Description

The Amani flatwing has a long, extremely slender abdomen, which is darkly coloured with a conspicuous white tip. Its wings are distinctly narrower at their base than at their tip, and the males have a broad brown band close to their wing tips.

Range

It is endemic to the Amani Sigi Forest of the East Usambara Mountains

. The Amani flatwing population appears to be largely confined to a 500 meter long stream in the Amani-Sigi Forest Reserve, although a single male has been found outside of this reserve.

Habitat

Adult damselflies occur along clear, fast-running streams that are heavily shaded by closed canopy vegetation. Its natural habitat

, mainly for conversion to agricultural land. The few remaining forests of the East Usambara Mountains where the Amani flatwing is found are under considerable pressure. The main, viable subpopulation of Amani flatwings is relatively safe within the Amani-Sigi Forest Reserve, any other subpopulations within the vicinity are either already extinct or maybe on the verge of extinction as a result of human encroachment, deforestation
Deforestation
Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a nonforest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use....

 and water pollution. Also the protected population of Amani flatwings leads a relatively precarious existence, containing fewer than an estimated 250 mature individuals.

Conservation

The stream around which the one remaining viable population lives is protected within the forest reserve in the East Usambara Conservation Area, and is therefore relatively safe from any danger. Any changes to this stream could result in the extinction of Amanipodagrion gilliesi. It has been advocated that an extensive survey of the whole area is urgently needed to locate any further remaining populations. This species is very close to becoming extinct. Dragonflies and damselflies can't survive well in captivity
Captivity (animal)
Animals that live under human care are in captivity. Captivity can be used as a generalizing term to describe the keeping of either domesticated animals or wild animals. This may include for example farms, private homes and zoos...
