Acleros mackenii Trimen 1868

Acleros mackenii (Trimen) (Fig. 68, S genitalia)
Pamphila (?) mackenii Trimen, 1868: 95 (Durban, Natal).
= Apaustus olaits Plotz, 1884c: 156 (Loango).
= Acleros instabilis Mabille, 1889: 168 (Zanzibar).
= Acleros nyassicola Strand, 1920a: 153 (Nyasaland).
= Acleros aurifrons Strand, 1920a: 154 (Nyasaland).
= Acleros mackenii f. denia Evans, 1937: 118 (Natal).
All six of the above names have been retained as "forms" by Evans (1937: 118-119), of which "olaus" is the Guinean one. Quite probably mackenii may be divided into geographic isolates, but Evans' solution of calling them "forms" is not a satisfactory answer. The material in Carnegie Museum collection is inadequate to undertake the task of delimiting subspecies and assigning names to them. It seems better to refer to all specimens as mackenii without resorting to infraspecific nomenclature for the present.
A. mackenii is reported from almost all of Africa south of the Sahara (Evans, 1937: 118-119).

There is comparative material in Carnegie Museum from Cameroon, Uganda, Kenya and several South African localities.

Acleros mackenii, the Macken's skipper or Macken's dart, is a butterfly of the family Hesperiidae. It is found in Western, Eastern and Southern Africa.

The wingspan is 27–32 mm for males and 29–33 mm for females. Adults are on wing year-round but are more common in late summer, autumn and winter than in the hotter midsummer months.

The larvae feed on Rhus species (including Rhus corarius) and Acridocarpus species (including Acridocarpus smeathmanni).
