Acylophorus salifi Lott, 2010

(Fig. 22)

Material examined. NAMIBIA: Kavango: Popa Falls, banks of Okavango, 18O7’S 21O35’E, M Uhlig, 27.ii.1992, 2.iii.1992, 13.iii.1992, 1.iv, 1993, 17.iv.1993, 22 (ZMHB).

Discussion. The new records extend the known range of A. salifi to Namibia. Fig. 20 updates the distribution map given by Lott (2010). The bodies of all the Namibian specimens are coloured black with reddish elytra. This is the dominant colour form both in the southern populations found in Zambia and Zimbabwe and in West African populations. In the Congo catchment, the dominant colour form consists of a uniform brown colour and populations are subject to considerable variation in the form of the aedeagus. It may be that the Congolese populations represent a complex of species.
