Key for the identification of female Nomada View in CoL in South Africa

The identity of the male N. whiteheadi and another unnamed male is doubtful (see explanations above). Only the males of N. kobrowi and N. gigas are known with certainty. The illustrations, in combination with the descriptions, should enable the identification of those males. Hence, a key only to female Nomada of South Africa is provided here.

1 Scutellum completely reddish-brown ( Fig. 5 View Figs 1-6 ) ............................. Nomada kobrowi BRAUNS

- Scutellum with two reddish-brown spots (e.g. Figs 27 View Figs 23-28 , 49 View Figs 45-50 ) ................................................2

2 Metasoma with yellowish-white transverse stripe on T2 ( Fig. 28 View Figs 23-28 )..... Nomada gigas FRIESE View in CoL

- Metasoma black and reddish-brown, without yellowish-white maculation.........................3
