Big-eared roundleaf bat
The big-eared roundleaf bat (Hipposideros macrobullatus) is a species of bat in the family Hipposideridae. It is endemic to Indonesia, known from Kangean Islands, southwestern Sulawesi and Seram Island. It roosts in caves and tree hollows and probably forages in woodland. It is threatened by habitat loss through logging and other human activities.

Taxonomy and etymology
It was described in 1941 by American zoologist George Henry Hamilton Tate. Tate described it as a new subspecies of the bicolored roundleaf bat, with a trinomen of Hipposideros bicolor macrobullatus. The holotype had been collected by G. Heinrich in 1931 in Maros, Indonesia. Tate wrote that its skull was "noteworthy on the account of the large bullae," likely inspiring the specific epithet "macrobullatus" from Ancient Greek makrós meaning "large" and Latin bulla. In 1986, it was revised to full species status.
