Remarks. Anteon fiorii was separated from A. proteicolum based only on the different colour of the ♀ (the ♂ is unknown): mostly testaceous-reddish in A. fiorii ; mostly black in A. proteicolum (Olmi 2006) . However, subsequently a study of many specimens from South Africa showed that the colour is very variable, suggesting that keeping the two species separate is unsustainable. For this reason, Anteon fiorii is here considered the senior synonym of A. proteicolum . Anteon fiorii is also very similar to A. kivuanum (Benoit) . The only difference between A. fiorii and A. kivuanum is also in respect to the colour of the ♀: mostly black in kivuanum , mostly testaceous-reddish in fiorii . The only known ♂ is that of A. kivuanum . Both species were collected in South Africa (Ashburton) during an temporally extensive Malaise trap survey. The chela of the two species is similar and hence the probability that the two species are conspecific is very high. However, in this case the ♂ of only one of the two species is known, and hence we prefer to wait for the discovery of the ♂ of A. fiorii before reaching a decision on species delimitation of these two taxa.
