In Fiji: Adelomyrmex hirsutus is a dark shiny species with wide well-defined foveae evenly distributed across the head and gaster. Although there is some minor variation in the sculpture across the archipelago, there is no morphologic evidence of highly structured populations. The specimens from New Caledonia that are reported as A. hirsutus (Wilson & Taylor, 1967) were apparently not examined by Fernndez (2003), who did not include the island as part of the Adelomyrmex distribution, although they do lend circumstantial credence to the Gondwanian origin hypothesis. The two New Caledonian specimens examined for the present study match poorly against the type specimen and the additional Fijian material. Though near A. hirsutus, the New Caledonian specimens entirely lack the distinctive foveae of the Fijian specimens, and in profile the petiole is characterized by a significantly narrower node and longer peduncle.

The single specimen Mann collected was a worker of A. hirsutus found beneath a stone, and his conclusion that the species was hypogaeic is supported by recent collections. All of the specimens collected during the recent survey were taken from sifted litter.
