variation exists between the Vanua Levu type series and the minor workers collected in malaise traps from Taveuni. The propodeal spines of the type series are bifurcate, with a distinct anterior point in addition to the posterior point, whereas the anterior point of the Taveuni specimens are reduced to blunt angle, and the posterior points are longer than those exhibited by the Vanua Levu specimens. Additionally, the genal carinae of the type series come to a more definite point, whereas those of the Taveuni specimens are more blunt.

Remarkable, in itself, suspicion of erroneous data is further compounded by the observation that all other known records of the species are taken from the tallest peaks of Vanua Levu and Taveuni. It is with caution that the locality data is recorded here, and I refrain from including it in the presented figures.</paragraph>
