Forcipiger flavissimus is very similar, the two species are nearly undistinguishable when observed in the environment. Main differences are: snout is longer in F. longirostris, mouth gape is larger in F. flavissimus, F. longirostris has grey spot in the white area under the mouth slightly more pronounced.
