Sulawesi as never part of Malaya. It was ruled by natives until first the Portuguese and then the Dutch arrived in the 1660s. From 1669 The Dutch East India Company ruled, then it became part of the Dutch East Indies in 1905. Apart from a period during WWII, the island has been part of the Republic of Indonesia.
I have not been able to find any proof of C. pareparentis parvidentata existing outside Sulawesi, but will keep looking. I’m sure the case will stay open for a while yet 😉
