Comments.

Acupalpa glossa sp. n. is similar to Acupalpa dolichorhyncha sp. n. in colour pattern and elongated mouthparts, but is easily differentiated based on leg colour. This species is known only from the type series collected in Victoria.

Etymology.

The specific epithet is derived from Gr. glossa, tongue, referring to the elongate mouthparts.
