Key to the species of Congomochtherus 

This key, modified from that of Londt and Tsacas (1987), includes a few additional characters. Identifications should be checked by comparing male terminalia with the illustrations provided ( Figs 5-11View Figs 5-11), in addition to those supplied by Londt and Tsacas (1987).

1 Katatergal macrosetae predominantly black (accompanied by few, fine white setae) (♂ terminalia as Fig. 8View Figs 5-11) (Central Africa) ............................. lobatus Oldroyd, 1970 

- Katatergal macrosetae yellow-white ...................................................................... 2

2 Antennal setae primarily black, a few white basoventrally on scape; postmetacoxal area membranous (bridge absent); female cerci with short spine-like setae (East & southern Africa) ...................................................................................................... 3

- Antennal setae primarily white, a few black distolaterally; postmetacoxal area bridged by a sclerotised bar; female cerci fine setose only (South Africa) ......................... 6

3 All femora with short brown-orange region proximally (East Africa) ................... 4

- Femora uniform black (tiny patches of orange colour may be seen but never on all femora) (southern Africa) ....................................................................................... 5

4 Anatergal setae black; T1 with at least a few black macrosetae laterally; hypandrium with subapical tuft of black setae (♂ terminalia as Fig. 10View Figs 5-11) ...................................... ...................................................................................... penicillatus ( Speiser, 1910) 

- Anatergal setae white; T1 with white macrosetae only; hypandrium with apical tuft of white setae (♂ terminalia as Fig. 9View Figs 5-11) .................. oldroydi Londt & Tsacas, 1987 

5 Mystax occupying more than half the distance between antennal bases and lower facial margin; male terminalia mainly black, hypandrium with a pair of black, narrowly separated setose tufts distomedially (♂ terminalia as Fig. 6View Figs 5-11) (widespread southern Africa & East Africa) ............................................ elferinki Londt & Tsacas, 1987 

- Mystax occupying a little less than half the distance from antennal bases to lower facial margin; male terminalia mainly red-brown, hypandrium with a pair of white, widely separated setose tufts distally (♂ terminalia as Fig. 5View Figs 5-11) (Namibia & Angola). ........................................................................................ acuminatus Oldroyd, 1974 

6 At least a few white setae on posterior part of ocellar tubercle; mystax occupying more than half the distance from antennal bases to lower facial margin; male hypandrium with longish, black macrosetae distolaterally (♂ terminalia as Fig. 7View Figs 5-11) (South Africa: Western, Eastern and Northern Cape) ..................... inachus Londt & Tsacas, 1987 

- Ocellar setae all black; mystax occupying less than half the distance from antennal bases to lower facial margin; male hypandrium with short, white setae distolaterally (♂ terminalia as Fig. 11View Figs 5-11) (South Africa: Eastern Cape) ............................................ ................................................................................ potamius Londt & Tsacas, 1987
