Range Description

This species is known from western Angola [Namibe: Konondoto, Cafita and Ponang Kuma (Boulenger 1919) and Luanda (under the name Hildebrandtia myotypanum)] and from the Angolan central plateau [Bié (Bocage 1879), Bingondo, Huambo, Galanga (Bocage 1895), Bimbe (Monard 1937), Huíla, Kuyango, Mulondo, Osi (Boulenger 1919), Dongue, Cunene, Ondjiva, Catequero (Poynton and Haacke 1993) and Lagoa Nuntechite (N. Baptista fieldwork 2016)], between 1,500–1,800 m Asl. Its extent of occurrence (EOO) is 231,812 km2.

A record from Zimbabwe (Eldorado) has been identified as this species, but is currently assigned to H. ornata and requires further taxonomic work to verify its' identity (N. Baptista pers. comm. August 2016).

Habitat and Ecology

If this species is similar to H. ornata, it is a fossorial savannah species that breeds explosively in temporary waterbodies.

Population

There have been no recent records, presumably due to lack of herpetological work within its range. Poynton and Haacke (1993) suggested that Angolan populations of Hildebrandtia ornata approached this species morphologically.

Population Trend

unknown

Major Threats

There is no information available on threats to this species.

Conservation Actions

Conservation Actions
Based on its known range, it presumably doesn't occur in any protected areas. 

Research Needed
The taxonomic status of this form, and its relationship to H. ornata, needs to be resolved. Research is also needed on the population status, ecology and threats to this species.

Red List Status

Data Deficient (DD)

Rationale

Listed as Data Deficient in view of continuing doubts as to its taxonomic validity as well as absence of recent information on its extent of occurrence, status and ecological requirements.

Taxonomic Notes

It was removed from the synonymy of Hildebrandtia ornata by Perret (1976), although this was implicitly not accepted by Poynton and Haacke (1993), or Channing (2001).

The taxonomic status of this species, H. ornata and their relationship need urgent review; however as this species' type locality is Angola, it seems justified to recognise the majority of the Angolan records to belong to it (N. Baptista pers. comm. August 2016). The records from the Cunene region collected by Poynton and Haacke (1993) could probably correspond to H. ornata, although the authors suggested that the subpopulations approached this species morphologically (Marques and Ceríaco pers. comm.).
