Comments
Acupalpa minuta sp. n. is closely related to Acupalpa minutoides sp. n., sharing characteristics such as very small size, two notopleural setae and an antenna with a short scape and a greatly elongate flagellum. It can be differentiated based on the colour of the setae on the coxae and by the width of the frons. This species is known only from a single male individual from Western Australia.
Etymology
The specific epithet is derived from the L. minutus, small, little, referring to the diminutive body size.
