I cann't see the images of O. jopas and O. medus posted.Originally Posted by Psyche
All the Mycalesis spp. have the tornal ocelli in space 1b.
The female of O. jopas have a diffuse band.

PS. How do you differentiate between J. aratus & fractilinea? I find the undersides practically identical.
J. fractilinea has a bluish tinge (underside), larger and is from Sulawesi but J. aratus without any bluish, smaller as illustrated by D''Abrera and distributions are Malay Peninsula, Java, Sumatra, Borneo and Palawan (but 'DÁbrera have not indicated it is from Sulawesi). The forewing uppersides of males (the forewing marginal black stripe extended to the apex for J. fractilinea and without a submarginal faint black stripe) and females have more different features.
