Strumigenys missouriensis Smith, 1931

Distribution. USA; in eastern USA from Florida to Virginia, west to Arkansas.

Comments. Strumigenys missouriensis probably represents a complex of species is an extremely wide-ranging and morphologically variable species. Because it is most morphologically similar to S. lucky and occurs in sympatry, I have included it here and in the key but not in the synoptic list of western USA species. A more thorough taxonomic treatment of S. missouriensis across its range is needed.
