  • NEBOTHRIOMYRMEX [Dolichoderinae: Leptomyrmecini]
    • Nebothriomyrmex Dubovikov, 2004a: 522. Type-species: Nebothriomyrmex majeri, by original designation.


The name of the new genus is formed by the negative prefex “ne” and the name of the genus Bothriomyrmex, to which specimens of the new species were erroneously referred previously.
