Atherigona bundongoana van Emden, 1940: 131 , figs 23, 59; Deeming 1971: 176, figs 125, 126; Deeming

1979: 45, fig. 34 (female tergite 8).

Diagnosis: This species can be distinguished from others by the combination of either yellow or infuscated (see below) frontal vitta, yellow palpi and legs. The hypopygial prominence is truncated with extended lateral ridges leading towards anteriorly projecting tubercles. The trifoliate process has the median piece greatly dilated in profile, being wider than the lateral plates.

Distribution: Burkina Faso, Democratic Republic of the Congo, Kenya, Nigeria, South Africa (new), Uganda.

Remarks: The specimens with yellow frontal vitta would key to near A. pallidipleura Deeming, 1971 when using the key to Afrotropical species in Dike (1989 a), but differ from it in having the frontal vitta yellow instead of infuscated.Also the trifoliate process shape did not match. If run through the key as having the frontal vitta infuscated, they key easily to A. budongoana . This then is the first record of variation in frontal vitta colour for this species.
