Comments
Acupalpa westralica sp. n. is known only from the holotype female from southern Western Australia. This species superficially resembles Acupalpa rostrata in colouration, but the head shape suggests a close relationship to Acupalpa notomelas sp. n.
Etymology
The specific epithet is derived from the western distribution of this species.
