Taxonomic History (provided by Barry Bolton, 2019)
Distribution: Geographic regions
(According to curated Geolocale/Taxon lists): Oceania: Fiji
, Solomon Islands Biogeographic regions
(According to curated Bioregion/Taxon lists): Australasia
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
sp. FJ02 are most similar in morphology to A. kinomurai
(Japan) and A. sauteri
