Tolaus (Epamera) alienus sophiae subsp. nov. is described, and notes on its early stages, habits and distribution are given. TIolaus (Epamera) alienus Trimen is widespread in Africa from Natal to southern Sudan and northern Nigeria. It has until now been divided into three subspecies. The nominate subspecies occurs in South Africa (Natal and Transvaal), Mozambique, Swaziland, Botswana, Zimbabwe, southern Tanzania, Malawi, and Zambia, with Umfuli River in Zimbabwe as its type locality. I. (E.) alienus bicaudatus Aurivillius is found in northern Cameroun, northern Nigeria and Upper Volta. I. (E.) alienus ugandae Stempffer occurs in Uganda, Kenya and southern Sudan. In 1984, J. (E.) alienus was recorded and bred by Mr H.C. Ficq from localities in the Grootfontein area of Namibia constituting a population apparently geographically isolated and constantly different from others of the species. Extensive investigation of habitats to the north and east of this population failed to reveal any specimens nor any of the particular Tapinanthus sp. (Loranthaceae) with which this population is associated. This particular plant is different from that used by the nominate subspecies and has not been seen by Mr Ficq in any other locality. Specimens of the plant have been taken for study but it is at present unidentified. We therefore regard tthis population as a distinct subspecies and name it after Mrs Sophie Ficq, the wife of the discoverer.
