According to Les Day, There are two different forms of Doleschallia bisaltide in Koh Samui. One is ordinary ssp.pratipa and another is close to Doleschallia bisaltide andamanensis or Doleschallia polibete. Yong & Hashim,2002 reported it from P.Malaysia as Doleschallia australis. Then, Eliot,2006 pointed out, He treated it as "?bisaltide var." and has known from W.Malaysia and Sinpapore, moreever the larvae is also different from ordinary bisaltide.
I suppose the specimen from Phuket figured in Kimura et al.,2016 is also possible to be this taxon. And recently it is found in Koh Phangan by Antonio Giudici. This strange taxon seems to prefer to be distributed on small islands. Further taxonomic study is needed.
