Primary type information:
Type-material: 2 syntype workers. Type-locality: Singapore, “SING”, and “SING. 55/9 (A.R. Wallace). Type-depositories: BMNH, OXUM.
Type notes:
One specimen in OXUM (“SING”), and one in BMNH (“SING. 55/9”). In the original description of Odontomachus rixosus, Smith states that the thorax is “tranversely striated.” The BMNH specimen more or less fits this description, whereas the OXUM specimen has weakly whorled, not transverse, striation on the pronotum.
