2. Group of rimosus -

Dr. Weber did not fail in discovering a flaw in my grouping. The rimosus-group, which I already set up in 1962, did not quite live up to expectations. As a matter of fact, longiscapus and to a lesser degree also wheeleri , costatus and possible allies, do not completely conform to the group definition. While definitely distinct from the strictly homogeneous strigatus-group, they might be set apart as a third group within the genus. This situation has already been recognized in the second part of my Cyphomyrmex revision (Kempf, 1965: 163, 166-7).
