Romblonella

Very little is known about the biology of these uncommon ants. The limited biological information suggests that they nest arboreally in twigs and forage on low vegetation.



Worker of R. heatwolei from Queensland.

Identification
The upper surface of the head has a pair of shallow grooves (antennal scrobes) for the reception of the antennal scapes which are bounded above by ridges (frontal carinae). The node of the petiole is about the same length as the petiole so that there is only a very short narrow section (peduncle) in front of the node. The lower surface of the petiole has a small tooth or angle near the attachment with the propodeum. The propodeum is armed with a pair of long, stout spines.

The antennal scrobes, well developed propodeal spines and the shape of the petiole will separate these ants from others in Australia.
