In year 2012, Gan CW, a senior member of Nature Society Singapore Butterfly Group photographed a larger than usual Cornelian looks alike butterfly. It was then identified as Cornelian (Deudorix epijarbas) but Gan noted it was larger then the usual Cornelian.
Until recently, with the help of Dr. TL Seow (a Malaysian butterfly expert), the butterfly then identified as The Deudorix staudingeri (The Large Cornelian).
The species is rare, known only from Singapore, P. Malaysia, Borneo and Nias (Indonesia). The Large Cornelian (D. staudingeri) may be confused with the commoner Cornelian (D. epijarbas), but on average it is larger. The male is deeper red on upperside. On underside the white striae are poor, sullied whitish and fading, the dark striae are more prominent than in D. epijarbas. Always with diffuse dark post-fiscal spots on hindwing.
