Notes
Examples from Chiang Mai and Laos have more brighter ground color on the upperside. On the other hand, example from Than To, Yala has darker blue ground color on the upperside as Kimura et al.,2014 pointed out. Although they treated it as ssp.lycaenaria, the markings on the underside of both wings is same as ssp.democritus. I consider it is transition form between ssp.democritus and ssp.lycaenaria. In Thailand, definit ssp.lycaenaria has been found in Betong dist., Yala and Narathiwat.
