Heteroponera pendergrasti
Taylor, 2015

Known only from Lamb Range, the northern rampart of the Atherton Tableland. H. pendergrasti is possibly endemic there.


Taylor (2015) - Characterized in the H. ecarinata species complex by heavy sculpturation, dark blackish color, with dark brown legs and antennae, and distinguished from the similar Heteroponera ecarinata by differences in sculpturation (particularly of the frons and second gastral tergite), coloration and structure of the petiolar node. Fore-coxae and posterior surface of node superficially microsculptured; propodeal declivity shining, with weak, superficial dorsally-directed radial striae; its sides distinctly sculpturally bordered, the posterolateral edge in profile micro-serrate as a result of minutely extended cuticular points along the sculptural border. Sculpturation of second gastral tergite more distinctly longitudinally deployed than in H. ecarinata (refer Figs).
