Material examined: 1^( AMNH [AH 3293]), Brandberg, hill 282, opposite Orabes Wall [ 21°15'S : 14°38'E ], 1.ii.1981 , A. Harington, sympatric with H.conspersus , P. kraepelini , O. jenseni , O.lamorali and O. wahlbergii ; 3 _ Messum Crater area [ 21°25'S : 14°13'E ], 21.i.1981 , syntopic with P.brevimanus and P. gracilis (2 _ AMNH [AH 2165]), 23.xii.1988 (1 _ AMNH [AH 4117]), A. Harington. Ecology and distribution: This lapidicolous species ( Fig. 15 ) shelters under stones and in grass tussocks (Lamoral 1979; Prendini 2001 b ) on rocky outcrops and gravel plains in areas surrounding the Brandberg ( Fig. 1 ) and adjacent landforms (e.g. the Messum Crater). Although it may also occur in Angola , this species has been recorded only from Namibia and South Africa (Lamoral 1979; Prendini 2005 a ).
