Justification:
The previous assessment of Vulnerable was based on information from the Malawi part of the species' range only.
This species is widespread and common over a wide region in Mozambique. Extends into areas of southern Malawi, northern South Africa and south-eastern Zimbabwe. Habitats are abundant. Localised impacts are known from the southern range for the species where it may be locally rare and threatened.

Geographic Range

| Range Description: |
Central Mozambique coastal plain from the Zambezi River south to the lower Mkuze in KwaZulu-Natal, South Africa. Present in a few pans in the Kruger National Park, South Africa (lower Limpopo system). Extends into the Gona-re-Zhou National Park region of south-eastern Zimbabwe and southern Malawi (Lower Shire River).

Habitat and Ecology
[top]
| Habitat and Ecology: |
Usually seasonal pools that are not connected to the river system. May be present in swamps intermittently connected to floodplains but the species seems to be predated upon or out-competed by riverine species.
|
| Systems: |
Freshwater |
| Major Threat(s): |
Has been impacted by insecticide spraying and road building activities, however, these impacts are localised.
|
Conservation Actions
[top]
| Conservation Actions: |
Damage to pans and wetlands should be avoided by road builders. Aerial spraying for tsetse and mosquitos should where possble be replaced with more targetted methods e.g. traps or spraying of insect sources.
