Heteroponera darlingtonorum

Specimens have been collected from rainforest, from both litter and soil.

Identification
Similar to Heteroponera relicta but with distinctively different sculpturation (compare Figs, notably the sculpture of the gastral dorsa). First and second gastral tergites moderately shining, but densely, finely point-punctate, with overlain, scattered, small, very weakly expressed foveate punctae on the first tergite. Bodily proportions and general structure, sculpturing of scrobes, propodeal declivity and node posteriorly as in H. relicta; Humeral epaulets similarly developed; propodeal dorsum in profile less strongly sloped posterodorsally; the declivity less strongly laterally margined and more narrowly triangular (apex dorsal).

Etymology
Named for Philip J. Darlington Jr, his wife Elizabeth Koch Darlington and their son Philip Jr. In 1956–57 they pioneered modern concentrated large-scale insect taxonomic survey in Australia by spending eighteen months living in a field-truck collecting carabid beetles and other insects, including ants, for the Harvard University Museum of Comparative Zoology (Darlington, 1960).
