Rationale

Peringueyacris namaqua is found in the Namaqualand region of South Africa. It is assessed as Vulnerable (VU) due to the fairly restricted geographic range of the species, with an extent of occurrence (EOO) of less than 15,000 km² and a limited number of locations (no more than 10). In addition, the EOO, number of mature individuals, and number of sub-populations are inferred to be declining, based on threats to the habitat of the species resulting from climate change (warmer and drier conditions), agriculture, and mining, as well as the species being very rarely encountered in the field.

Distribution

Peringueyacris namaqua is endemic to South Africa, where it is found in the Namaqualand region along the west coast of the country. Its extent of occurrence (EOO) is ca 14,000 km².

Population trend

Trend

Peringueyacris namaqua emerges seasonally, and has been observed from August to November. The population size and trends have not been studied, but the number of mature individuals and sub-populations is inferred to be declining based on ongoing threats to the species' habitat. The species is very rarely encountered in the field, despite the geographic area where the species occurs being fairly well surveyed.

Threats

Threats to this species include climate change, resulting in warmer and drier conditions, as well as habitat destruction due to overgrazing by livestock, and agricultural and mining activities. Based upon the threat of overgrazing, the number of locations is between six and ten.

Uses and trade

This species is not utilised.

Conservation

There are no conservation actions for the species, and it is unknown whether it occurs in protected areas. Research into its ecology, threats and population trend is required. Remaining habitats of this species need to be protected and grazing regimes need to be adapted to avoid future declines.
