Atherigona yorki Deeming, 1971: 147 , figs 8–12; Deeming & Overman 1987: 117; Pont 1991: 343; Dike 2003: 218 (distribution).

Material examined: 1♂, Katima Mulilo District, Salambala pan, 17°50'00''S, 24°35'58''E, 23–27.xii.2002, A .H. & M.K.

Remarks: Although almost the entire type series was recorded as developing in cereal shoots, this species is predaceous on other soft-bodied larvae.Additional descriptions and notes on the puparia were provided by Skidmore (1985: 295). Overlooked in the original description of the species was the fact that the inner side of the surstylus ( Fig. 23 , sur) bears a pair of tooth-like spines ( Fig. 23 , sp).
