Notes:
Hemming (1967) stated:-
When discussing the genus Gonepteryx Doubleday said that, if it were to be thought desirable to subdivide that genus, various names were available, including the name Dercas, which had already been indicated by Boisduval for Colias verhuelli Hoeven. Doubleday's information regarding the name Dercas must have been drawn from manuscript sources, for that name had not been published. Doubleday must therefore be treated as its author; as the above species was alone cited by Doubleday, it is automatically the type-species of Dercas by monotypy.
