. The genus is characterized by long erect setae forming four loose tufts dorsally and laterally on the pronotum. The majority of the remaining pronotal surface is densely covered with flocculent, wooly, tan-colored setae that obscures the cuticular surface. When viewed anteriorly, the visible pronotal cuticle medially is triangular in shape. The elytral surface also has distinct puncture rows in addition to rows of recumbent and erect setae.

). At Cape Town, occasional rainstorms occur during the summer, with generally increasing frequency towards Mossel Bay in the east. Additionally some sheltered inland areas are relatively hot and dry. Hence, the diversity and complexity of temperature and rainfall patterns is no doubt responsible for the high floristic and faunistic diversity, with many endemic taxa including the species of
