Atherigona scutellaris Stein in Becker, 1903: 110 . Egypt . Atherigona laeta – authors nec Wiedemann (misidentifications). Described as a species of Coenosia from Mozambique ( Loew 1852: 660 ), this species ranges from Cape Province to Egypt and Yemen and from Nigeria to the Seychelles , Comoros and Madagascar . The holotype female is amongst the material recently discovered in the Smithsonian Institution. It is in poor condition, lacking both wings and having only one mid and one hind leg complete. Nevertheless, the frontal vitta can be seen to be yellow on anterior half, becoming abruptly black, and the palpus yellow. These characters, along with the tergal markings, leave one in no doubt that the concept of authors of this species is correct. The specimen is mounted on a ‘continental’ ( 39 mm long) pin and bears the following labels: 1) blue long rectangular “Inhamb. Pet.” in a copperplate hand. 2) red rectangular “ Type ” machine-printed. 3) as (1) above “ laevigata Loew ”. 4) grey rectangular “ Atherigona laevigata Lw. ” in Stein’s handwriting. This specimen is accompanied by a ♂ micropinned on pith on a black ‘continental’ pin and bearing the following labels, all of which are white rectangular: 1) “Africa or., Katona 904” machine-printed. 2) “Mto-ja-Kifaru” machine-printed. 3) “ Atherigona laeta (Wied.) ♂ det. Stein” [a misidentification, laeta being an oriental species with a superficial resemblance to laevigata ]. 4) “ Atherigona laevigata Lw. det. J.R. Malloch”. This specimen undoubtedly originates from the Hungarian National Museum, where the East African collection of K. Katona is deposited ( Horn & Kahle 1935: 131 ).

Remarks Females of the Kasarani material show a tendency to large size, being 5–5.4 mm in length, as against 3 mm in males, have the scutum and tergites more extensively darkened and a more accentuated frontofacial angle, whereas the material from Yemen is diminutive, being hardly more than half the length of the largest Kasarani female, is extensively pale and has a frontofacial angle of little less than a right angle. The Kawanda females resemble those from Kasarani. It is apparent that large species of this genus tend towards a more acute frontofacial angle (see Skidmore’s 1985: 301 , fig. 89g , figure of the head in profile of A. mitrata Séguy, 1955 ), and it would appear that large individuals of A. laevigata do the same. The darker colouration of the Kasarani material points to melanism associated with lower temperatures at high altitude. Extreme variation in colour pattern of Kenyan female material was figured ( Clearwater 1981: 309 , figs 9, 10a–d.) Distribution Angola , Comoros , Cyprus , D.R.
