Rationale

The Mute Winter Katydid (Brinckiella aptera) is Vulnerable under criterion B1 because its extent of occurrence is relatively small (~12,500 km²), it has only been recorded in four locations, and its habitat quality is estimated to be in decline. This species occurs within the Fynbos and Succulent Karoo biomes, both of which are notable biodiversity hotspots, naturally geographically restricted and under anthropogenic stress.  This habitat type is predominantly utilized for livestock grazing, cultivation with annual crops, and urban development which may be detrimental to the host plants of the species. The genus of this species experienced an adaptive radiation in the region, with at least 9 species known in a relatively small geographic area. This species is not known to occur within any protected areas.

Distribution

The Mute Winter Katydid is endemic to the Northern and Western Cape Provinces of South Africa.
