oa Annals of the Natal Museum - The systematics and ecology of new genera and species of primitive Stygnocorini from South Africa, Madagascar and Tasmania (Hemiptera: Lygaeidae)

Volume 20, Issue 2
  • ISSN : 0304-0798



Three new genera and seven new species of primitive stygnocorine Lygaeidae are descriptionbed. One genus is represented by four South African and one Madagascar species. A second genus by a single species from Table Mountain, Cape Town, and a third by a single species from Tasmania. The relationships of these genera to others of the tribe is discussed. The position of the Stygnocorini within the Rhyparochrominae is analysed and a key included to the world genera. Paracnemodus Slater is removed from the Myodochini and placed in the Stygnocorini. The zoogeographic implications of the distribution of these new genera is discussed relative to the distribution of other members of the tribe and to past climatic conditions in southern Africa. Keys are included to all the species. Descriptions of the nymphs and eggs as well as habitat and ecological information is given for several of the South African species.
