In Fiji:
In the most recent survey, Acropyga lauta was only collected from a single locality in Vanua Levu, where workers were found in the soil while excavating a Pheidole nest. During review of museum specimens at the NMNH, we found collections from Kadavu made by Mann that were apparently overlooked in his monograph. The Fiji specimens are larger than those from other populations of the species (LaPolla, pers. comm.). Acropyga lauta is one of four ant species on Fiji currently known to occur on only a single additional island archipelago in the Pacific.
In the Solomons, A. lauta is reported as being trophophoretic (Johnson et al., 2001), and has been associated with the mealybugs Eumyrmoccus kolobangarae and E. kusiacus (LaPolla, 2004). The species is tentatively placed in the myops group by LaPolla, with the caveat that the torulae are more closely set than in the other species of this group. Acropyga lauta and Acropyga sp. FJ02 are most similar in morphology to A. kinomurai (Japan) and A. sauteri (Taiwan).
