Similar species Comibaena quadrinotata
"The wing pattern of Comibaena fuscidorsata
are similar to those of Comibaena quadrinotata.
However the wings are tinged with a yellowish colour
rather than blue, and the tornal and apical patches
are larger. The brown forewing tornal patch is semicircular,
but pointed in Comibaena quadrinotata,
reaching or slightly extending beyond CuA2."
