Heteroponera wilsoni

Known from Northeastern Queensland. Specimens were collected from Berlese funnel of sieved rainforest leafmould, litter or moss from trees or rocks. Sympatric with Heteroponera rhodopygea at all sites of record except Mossman Bluff, where H. wilsoni is directly sympatric with Heteroponera relicta.

Identification
Taylor (2015) - Habitus similar to Heteroponera darlingtonorum (refer Figs) and Heteroponera relicta. Major sculpturation considerably different, as illustrated. Compared to H. relicta: antennal foveae superficially but more strongly sculptured, finely longitudinally striate; propodeal declivity shining, with some minute scaly microsculpture; posterior face of petiole smooth, shining. Vertexal border similarly concave in frontal view; posteroventrolateral extensions of occiput and opposing humeral epaulets less pronounced; ventrolateral sub-dentate extensions of pronotum above fore-coxae less well-developed and less-acutely pointed; humeral shoulders in dorsal view less pronounced; propodeal dorsum in profile less inclined posterodorsally; petiole in side view relatively narrow, the subpetiolar process somewhat reduced.
