In older biological publications, you can find references to "Malaysia" before the country was established in 1967. This is because "Malaysia" originally was a biogeographical term to describe Borneo, Sumatra, Java and the Malay Peninsula all the way to Tennasserim.

I have found references to "West Malaysia" which actually meant Sumatra instead of the modern Peninsular Malaysia definition.

You have to be very careful when reading these older localities.
