A revision of the South African myrmecophile Diplocotidus (Coleoptera: Ptinidae)

The southern African myrmecophilous ptinine genus, Diplocotidus Peringuey, is redescribed, and two new species are described. New species and collection localities increase the known distribution from the Cape region to the Kruger National Park in the east, and central Namibia in the west. There is little doubt that the species are associated with ants in some manner as typified by the trichomes located on the pronota.
