Comments
Acupalpa melanophaeos sp. n.is a relatively large species from Western Australia with distinctive leg and abdomen colouration. It is morphologically similar to Acupalpa novayamarna sp. n. and Acupalpa notomelas sp. n. The coxae are pale in this species along with a rounded face, rather than protruding anteriorly in similar species (e.g. Acupalpa irwini).
Etymology
The specific epithet is derived from theGr. melanos, black; phaeos, light, shiny, referring to the scutum colouration.
