Encountered this skipper at the Sungei Buloh Wetland Reserve. It was rather tame and allowed me time to close in for a decent shot. The underside is much paler brown compared to the usual Caltoris spp., and the hindwing cilia are yellowish. The pic below shows one cell spot on the forewing, but there is a lower cell spot too (saw this when it moved to another perch).
Dr Seow, any idea on its species ID?
