Monomorium Mayr


Genus Monomorium Mayr  

California appears to have a single indigenous species of this genus, M. ergatogyna   , a ground­nesting species which is widely but patchily distributed throughout the state except at high elevations. The reasons for treating M. wheelerorum   as a junior synonym have been discussed above (under “Taxonomic Changes”). The introduced Pharaoh’s ant, M. pharaonis (Linnaeus)   , is a frequent pest in buildings in urban California. A second introduced species, similar to M. pharaonis   but with a more elongate head and more shagreened sculpture, has been collected once in the state (images and locality information on AntWeb).
