[1] Hill's roundleaf bat was described as a new species in 1993 by Tim Flannery and Donald Colgan.

The holotype had been collected in the Bewani Mountains near Imonda Station in 1990 by P. German and L. Seri.

The eponym for the species name "edwardshilli" was British mammalogist John Edwards Hill, "in recognition of his outstanding contributions to bat taxonomy".

[2] Hill's roundleaf bat is endemic to Papua New Guinea in Oceania.

It has been documented at a narrow range of elevations from 200–300 m (660–980 ft) above sea level.
