It was
described as a new species in 1918 by Danish mammalogist
Knud Andersen. The
holotype had been collected in 1879 by
W. Davison in
Klang, Malaysia. It was presented to Andersen by
Allan Octavian Hume. It is considered a member of the
bicolor species group within
Hipposideros based on its
morphology. The holotype is the only known specimen of this species. As it was damaged, it is uncertain if the Malayan roundleaf bat is truly a distinct species. Its
species name "
nequam" is
Latin for "worthless." ==Description==
