Family Gomphidae
Microgomphus nyassicus – EASTERN SCISSORTAIL
Identification
Medium sized
Length reaches 43mm.
Microgomphus nyassicus is the smallest gomphid species in Southern Africa.
The Eastern Scissortail has the typical yellowish-green and black colouration of many gomphid species. It is best recognised by its small size, and distinctive clasper structure. It also has unusual, thick black, looped markings on the upper thorax.
Within the sub-region, the Eastern Scissortail is most similar to the Spined Fairytail (Lestinogomphus angustus). Both species are close in terms of size and colouration, but the Spined Fairytail has a far more slender abdomen and the two have very different clasper structures.

Behaviour
Highly elusive and easily overlooked. Interestingly larvae, exuvia and adult females are found more often than adult males. The males appear to spend much of their time in the shade of bushes and trees some meters from the river. Seemingly active for only a short period during the hottest time of the day, where it sits on sunny boulders and reeds close to the water. Females are found among trees and bushes not too far from the river. Despite its elusiveness, the Eastern Scissortail is fairly tame and confiding.
Status and Conservation
Very little is known about this species. The paucity of records from throughout its range suggests Microgomphus nyassicus is rare, but more data is needed. It is currently listed as of Least Concern in the IUCN Red List of Threatened Species.
An exuvia, believed to belong to this species was found at Oribi Gorge, KwaZulu-Natal in 1988. Another was found near the Komati River, Mpumalanga in 2018.
The first record of an adult in South Africa, was by Antoinette Snyman on the Blyde River, Mpumalanga in May 2019. See the identification image above.
Distribution
Erratically distributed in South-East Africa. Recorded from Southern DRC, Northern Zambia and Malawi as well as the border region between Zimbabwe and Mozambique and a few scattered locations in South Africa.
In South Africa it has been recorded from the Mpumalanga and KwaZulu-Natal provinces.
There are no maps for this species at present.
