From the IUCN Red List Species Account:

 

Range Description

This species is known from three localities: Pearly Beach, Grootvadersbosh Nature Reserve and Vrolijkheid Nature Reserve, Western Cape Province, South Africa (Channing et al. 2013). It is expected to be widely distributed in the southern Cape and Little Karoo (Channing et al. 2013). The three known localities 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 in temporary rain-filled pools from coastal sands and inland rocky areas (Channing et al. 2013). It presumably requires water for breeding by larval development, like other members of its genus.

Population

This species is known from a few species so that its population trend is unknown, but it is expected to be widespread and common.

Population Trend

unknown

Major Threats

Its temporary breeding pools are threatened by draining due to agriculture.

Conservation Actions

Conservation Actions
It occurs in Grootvadersbosh Nature Reserve and Vrolijkheid Nature Reserve. No conservation actions are currently in place for this species.

Research Needed
Studies on its population size, distribution and trends, life history and ecology, and threats are needed.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern because it is considered to be common and widespread and threats are not considered to be too severe. However, due to its recent description, information on its population status, life history, ecological requirements and threats need to be searched for.

Taxonomic Notes

This species was confused with Cacosternum platys, but it is now known to occur only in the southern Cape region (Channing et al. 2013).
