Markku Savela's website on Lepidoptera – page on genus Choaspes.
The common name similar awlking is that of taxon similis (vide Evans (1932)) which is not recognised as a valid species by Savela and by TOLWeb (ref its page on genus Choaspes). Taxon similis is now considered to be a synonym of taxon xanthopogon.
The species is considered to be furcata by LepIndex, and as furcatus by TOLWeb. Savela gives it as furcatus without appropriate reference for the change. Accordingly it is being retained as furcata, with furcatus as redirect, pending the availability of a proper reference.
