Byrrhidium convexum Scholtz & Howden, 1987 .

Widespread in Namaqualand from the environs of Nuwerus [31.149°S 18.358°E] in the south to Steinkopf [29.266°S 17.734°E] in the north. More or less confined to the Namaqualand Klipkoppe Shrubland vegetation unit as defined by Mucina and Rutherford (2006) .

Collected some distance from rock hyrax middens among Namaqualand heuweltjies ( Mima-like earth mounds, Lovegrove and Siegfried, 1986), but probably also associated with rock hyraxes.
