COMMENTS: The above material could be conspecific with H. paradisaea but differs slightly in coloration and we have therefore hedged in our identification, pending further investigation. Toxopeus (1940) provides further details and a map for his various collecting camps. If the Toxopeus material proves to be truly conspecific with H. paradisaea , then the subspecific name “ irianensis ” would also be synonymous with the former.
