Otus angelinae has a highly restricted range, being known from two localities, Gunung Gede Pangrango National Park and Gunung Tangkubanprahu, in West Java, Indonesia, where it has been recorded in montane forest between 1,400 and 2,000 m. The most recent published record is of two seen on the northern slope of Gunung Pangrango in 1985, but its calls are not documented (and it may be an unusually silent species), so that its status (and any threats) remain unclear.
Otus angelinae is listed as "Vulnerable" by the IUCN Red List.
