synonymized with the genus Chalepoxenus Menozzi 1922. A mor- 
phological comparison of the Leonomyrma holotype $ and an allo- 
type $ with material of Chalepoxenus muellerianus and C. kutteri 
revealed a close similarity in most relevant characters. It may be 
predicted that Chalepoxenus spinosus (nov. comb.) will be a slave- 
making ant like the other species of the genus. 
Acknowledgements 
I am indebted to Dr. A. V. Antropov and the Zoological 
Museum, Moscow, for having provided the type material of 
Leonomyrma spinosa. The Deutsche Forschungsgeneinschaft has 
generously supported our studies in Chalepoxenus.
