Least Concern (LC)
Assessors: V Clausnitzer F Suhling
Reviewers: V Clausnitzer F Suhling Michael J Samways B Samraoui J Boudot

Rationale (Changed due to Same category and criteria)

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.

In eastern and southern Africa, it 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.

Distribution

The species has been recorded from Kenya to Zimbabwe and north Zambia. Records in the database from southern Africa are likely to be another species

In eastern Africa, it has been recorded in Kenya, Tanzania, Uganda, Malawi and Burundi: rivers and streams in coastal Kenya and Tanzania, a wider distribution is assumed, as M. nyassicus is easily overlooked.

In southern Africa, this species is known from rivers and streams in Mozambique, South Africa, Zambia and Zimbabwe. A wider distribution is assumed, as M. nyassicus is easily overlooked. Only recently, an exuviae found in Natal in the 1980s has been identified as Microgomphus (Martens and Suhling 2005).

Population trend

Trend

No information available.

Threats

Water pollution and destruction of gallery forest and pollution due to agriculture and wood extraction are threats to this species.

Conservation

No conservation measures known but information on taxonomy, population ecology, habitat status and population trends would be valuable. Habitat/site based conservation is also required.
