Genus ACANTHOMYOPS Mayr 



Acanthomyops Mayr, 1862. Zool.-Bot. Gesell. Wien, Verh. 12: 699. 

 Type-species: Formica clavigera Roger. Monotypic. 



The ants of this exclusively North American genus nest in the soil, usually beneath objects, 

 and also in rotting logs and stumps. They are mostly subterranean in habit. The females and 

 workers have a characteristic citronella or lemon-verbena odor. Species of Acanthomyops are 

 sometimes of economic importance because they foster honeydew excreting insects and because 

 of their objectionable habit of nesting around foundations of buildings and beneath basement 

 floors. The vringed forms are often mistaken for termites.
