Ecology and distribution: This lithophilous species shelters in the cracks and crevices, and under the exfoliating flakes, of weathered rock outcrops and under stones resting on bedrock (Lamoral 1979; Prendini 2001 b ). It is endemic to Angola and Namibia (Lamoral 1979; Prendini 2005 a , b ) and has been collected in areas to the southeast of the Brandberg, but not on the Massif itself.
