Ecology and distribution:This semi-psammophilous species inhabits semi-consolidated to consolidated sandy and gritty substrata, where it probably excavates burrows in open ground and at the base of shrubs and grass tufts. All specimens collected to date were either captured in pitfall traps or at night by means of UV light detection (Lamoral 1979; Prendini 2001 b, 2004). It is endemic to Namibia (Lamoral 1979; Prendini 2004, 2005 a) and has been collected in the areas surrounding the Brandberg (Fig. 1) and adjacent landforms (e.g. the Messum Crater), but not on the Massif itself.
