Remarks. Bandella cerra   is known from Nothofagus moorei   dominated cool temperate rainforest in the Barrington Tops and Mt Banda Banda, in northeastern New South Wales. These sites are in the Central Eastern Rainforest Reserves of Australia (CERRA) World Heritage Area, hence the specific epithet.
