The latest effort to increase our knowledge of the Ethiopian Region was initiated by Wolfram Mey of the Museum für Naturkunde, Humboldt Universität, Berlin, Germany, and several collaborators, with an entomological survey of one of the most poorly known areas in Namibia, the Brandberg Massif. The first report on the three Brandberg expeditions (Mey 2004) provided a general introduction to their survey including an itinerary, description of collecting sites, and list of participants. It also provided the taxonomic treatment of 28 families of Lepidoptera. The present volume comprises the second and final report, with treatments for approximately 30 additional families. The taxonomic studies in both reports include related material from other areas of southern Africa in addition to the Brandberg. Of particular significance in Part 2 are the list of all species studied and the summaries of the Lepidoptera diversity of the Brandberg Massif compared with three other areas of Africa.
