This species is known only from two confirmed locations: Vissershok and Klipheuwel, northeast of Cape Town, Western Cape Province, South Africa, but it is expected to occur more widely (Channing et al. 2013). The two known locations are those confirmed by molecular techniques – although, because the habitat in these areas is continuous, it is likely that many of the additional records from the surroundings of the confirmed locations actually belong to this species (A. Rebelo pers. comm. August 2016).
Habitat and Ecology
The specimens were found on a flooded wheat field near temporary rain pools, during winter rain (Channing et al. 2013). Like other member of its genus, it breeds in temporary pools.
This species is currently known from a few specimens, therefore its population trend is unknown.
Its temporary breeding pools are threatened by draining and pollution due to agriculture.
No conservation actions are currently in place for this species. The Vissershok locality lays within the Cape West Coast Biosphere Reserve.
Studies on its population size, distribution and trends, life history and ecology, and threats are needed.
Red List Status
Least Concern (LC)
Listed as Least Concern because it has relatively large extent of occurrence (EOO) and area of occupancy (AOO) and threats are not too severe. However, given its recent description, information on its population status, distribution and trends, ecological requirements, life history and threats need to be searched for.
