This group is comprised of the anomalous Malagasy species.
 * Stigmatomma besucheti

Diagnosis
The morphology of S. besucheti isolates the species from other Stigmatomma in the Malagasy bioregion, and we place it in its own group based on the following worker characters (asterisks flag unique characters within the genus in the Malagasy bioregion):

1. * Ten antennomeres;

2. * Two maxillary palpomeres (palpal formula: 2:2);

3. * Calcar of strigil completely pectinate;

4. * Anterior face of the calcar of strigil with squamiform microtrichia basally;

5. * Posterior face of the calcar of strigil glabrous;

6. * Weakly raised longitudinal parallel carinae present on the dorsal face of metabasitarsus, with convergent apexes;

7. * Petiolar proprioceptor zone reduced to a small concavity.
