Taxonomy and etymology
The Hawaiian butterflyfish was first formally described by the American ichthyologist Leonard Peter Schultz (1901-1986) in 1952 with the type locality given as Nanakuli on Oahu in Hawaii.[4] The specific name honours Spencer W. Tinker who discovered it in 1949, trapping them in fish traps at 90 feet (27 m) off Oahu, Hawaii.[2]
