just to clarify, and i don't like the use of common names for identifying fish. But in general terms- the hawaiian lionfish, is NOT describing D brachypterus, and D brachypterus is not commonly found in the hawaiian islands.
D brachypterus is the name usually associated w/ "dwarf fuzzy lionfish", the scorpaenidae found Indo-West Pacific: Red Sea and East Africa to Samoa and Tonga, north to southern Japan, south to Lord Howe Island; Mariana Islands in Micronesia; as fishbase.org cites.
D barberi or the hawaiian lionfish is endemic to the hawaiian islands, looks somewhat similar to D brachypterus, and is usually associated w/ the common name you used above. Just to throw more confusion onto this pile, this common name "hawaiian lionfish" is also be used for Pterois sphex --another hawaiian endemic lionfish, but less frequently.
