Dolichoderus angusticornis Clark 

(Fig. 2)

Dolichoderus angusticornis Clark, 1930: 260  .

Types. 4 worker syntypes (3 (1 missing gaster) in MCZC; 1 in MVMA) from Burracoppin, Western Australia.

Diagnosis. Pronotum rounded, lacking spines, propodeum with elongate spines directed upward at angle of greater than 60 ° to horizontal plane (may be almost vertical), the angle between them approximately 45 °. The presence and angle of the propodeal spines will distinguish this species from all other Australian Dolichoderus  species.

Worker description. See Fig. 2. The available material varies little from the imaged individual.
