This species is very similar to Acupalpa melanophaeos sp. n., but can be differentiated by the pale genal setae, larger proportion of the pleuron being orange, and male frons slightly wider. Only the male is known for this western species.
Etymology
This species is named after the type locality of New Yamarna Homestead, Western Australia.
