Comments
Acupalpa semirufa is a common species in south-eastern Queensland and northern New South Wales. It is similar to Acupalpa divisa and Acupalpa yalgoo sp. n., but can be differentiated easily from the former by the orange leg colour (black in Acupalpa divisa) and from the latter by the projecting face (rounded in Acupalpa yalgoo sp. n.) and two wing bands (single band in Acupalpa yalgoo sp. n.).
