The presence of Rapala damona in Singapore has been confirmed by Dr Seow photos showing the upper side of the species from Jonathan Soong.
This species has been mis-id as Rapala suffusa and R. dieneces in the past due to the similarity of the underside of the 3 species.
Examining earlier records of Rapala suffusa and dieneces in iNaturalist revealed R. damona was in fact recorded on May 3 2017 by members of NSS Butterfly and Insect Group
Fleming stated that R. domano underside is a deeper darker, ochreous brown than either dieneces or suffusa.
Dr Seow has provided the keys to id the 3 species based on the underside :
R. damona Un. deeper ochreous (appear orangey brown); . orange crown often marked by a faint dark line. FW band ALWAYS distinctly curved/bent.
R. suuffusa ;Light ochreous to deep chrome yellow; orange crown diffuse; FW band strongly bent.
R. dieneces; Light ochreous to brownish ;orange crown diffuse, the defining dark line often absent ;FW band usually straight. may be slightly curved.
