Choerades serpentina (Bezzi, 1908) Loodt, 1977

Loodt, J. G. H., 1977, Afrotropical Asilidae (Diptera) 1. The genus Choerades Walker, 1851 and the descriptions of two new genera, Nannolaphria and Notiolaphria, from southern Africa and Malagasy Republic *, ANNALS OF THE NATAL MUSEUM 23, pp. 43-55 : 47

Oldroyd (1974) doubtfully assigned specimens from Malawi, Mozambique and South Africa to this species. I here present an illustration of the male genital bulb drawn from the only specimen available to me ( Fig. 5 ). Fused gonopodal setae curved in an S-like manner with distal points pointing outwards. Aedeagal structure very well developed and extended posteriorly.

The male terminalia of the specimen studied are quite distinctive and there should be no trouble recognizing this species. A comparison with the type specimens should reveal whether southern African specimens are indeed C. serpentina .

Material examined: SOUTH AFRICA: Natal: 1 ♂, Dukuduku , 22-24.1 II. 1968, Potgieter & Goode (Natal Mus.)
