Comments
Acupalpa dolichorhyncha sp. n. is a distinctive species with elongate mouthparts and orange-banded abdominal segments 1–3. This western species is morphologically similar to Acupalpa melanophaeos sp. n., also from Western Australia, and Acupalpa glossa sp. n. from Victoria.
Etymology
The specific epithet is derived from Gr. dolichos, long; rhynchus, snout, referring to the elongate mouthparts.
