MEXICO , CHIAPAS : 12 mi N. Ocozocoautla ( TAMU ) . TAMAULIPAS : Ciudad Victoria ( WPMC ) ; Ciudad Victoria , Canon La Libertad ( TAMU ) . DISCUSSION This common small species can be confused with no other United States species. The long flexuous hairs on the body of this ant readily distinguish it from our other Neivamyrmex . Throughout its range from the southern United States to South America this ant is morphologically quite uniform.
