The field work was supported by a grant of the Deutsche 
Forschungsgemeinschaft (Buschinger) and a grant of the Natural 
Science and Engineering Research Council of Canada (Francoeur). 
Summary 
Symmyrmica chamberlini was described by Wheeler (1904) from 
specimens taken by C.V. Chamberlin in 1902 in a colony of Manica 
mutica (Emery) near Salt Lake City. No further records of this 
species are known. In order to find out the systematic relations of 
Symmyrmica to other ants like Leptothorax provancheri Emery or 
those of the genus Formicoxenus, we have collected some new mate- 
rial in August 1982, in the Salt Lake City area. The morphology, 
female polymorphism, and wingless male together with biological 
features indicate that S. chamberlini is a species that should belong 
to the genus Formicoxenus.
