 * Acanthomyrmex foveolatus
 * Acanthomyrmex mindanao

Diagnosis
Dorsal margin of the head of the majors at most very slightly notched mesad so that in full-face view margin appears rounded or somewhat flattened, but not strongly bilobed. Other characters: majors with propodeal spiracle opening slightly smaller and less conspicuous than in luciolae group; basal funicular segments relatively thick (width of the second and third funicular segments more than 25% greater than their average length in minor workers and less than 50% in majors), except in A. notabilis; hypostomal teeth often absent in majors. Dorsal surface of gaster invariably with very few (if any) long hairs.

Distribution
All species in this group are from the Malay Archipelago; as yet none have been collected from the Asian mainland.
